如何使用 IronPDF 在 .NET Core 中生成 PDF 文件

Curtis Chau

Updated: 2026年7月19日

从 PDFPrinting.NET 迁移到IronPDF可将您的 PDF 功能从仅用于打印的库扩展到可处理整个 PDF 生命周期（包括创建、操作、提取、安全和打印）的综合解决方案。本指南提供了完整的分步迁移路径，在保留现有打印工作流程的同时，增加了 PDF 生成、HTML 转换和跨平台支持功能。

为什么要从 PDFPrinting.NET 迁移到 IronPDF?

了解 PDFPrinting.NET.

PDFPrinting.NET (Terminalworks; NuGet PdfPrintingNet) 是一个专注于在Windows环境中静默打印PDF的专用库。作为一个致力于静默打印现有PDF的工具，它简化了将文件以编程方式调度到打印机而不需要用户干预的任务。新的入口点是 PdfPrint 类；旧代码可能仍然引用遗留的 TerminalWorks.PDFPrinting.PDFPrinter。

其核心优势是静默打印——绕过通常的打印对话窗口，以便全自动工作流可以无人值守地运行。

关注打印的限制

PDFPrinting.NET专注于一小撮操作，并不撰写新的PDF内容。其范围包括打印、查看、基本编辑和栅格化现有文档：

**关注打印：**不撰写新的PDF内容——仅打印、查看、编辑和栅格化已有的PDFs。
**仅限于Windows打印：**受限于Windows打印基础设施，限制了跨平台的可用性。
**无HTML/URL到PDF API：**没有 HtmlToPdfConverter 和没有 WebPageToPdfConverter 类 — 这些功能在API表面不存在。
**有限操作：**基本的合并/分割/提取是通过 PdfPrintDocument 实现的; 没有水印或现代内容创作。
没有全面的文本提取表面。
没有表单填写或平铺。

PDFPrinting.NET 与IronPDF的比较

代码迁移示例

示例 1：HTML 到 PDF 的转换

之前 (PDFPrinting.NET)： PDFPrinting.NET 没有 HTML 到 PDF API — 没有 HtmlToPdfConverter 类。最接近的工作流程是用另一个库生成PDF，然后打印或交付文件：

// NuGet: Install-Package PdfPrintingNet
using PdfPrintingNet;
using System;

class Program
{
    static void Main()
    {
        // Step 1: Produce the PDF with another library (PDFPrinting.NET cannot).
        // Step 2: Print the existing PDF file.
        var pdfPrint = new PdfPrint("license-owner", "license-key");
        var status = pdfPrint.Print("output.pdf");
        Console.WriteLine($"Printed: {status}");
    }
}

// NuGet: Install-Package PdfPrintingNet
using PdfPrintingNet;
using System;

class Program
{
    static void Main()
    {
        // Step 1: Produce the PDF with another library (PDFPrinting.NET cannot).
        // Step 2: Print the existing PDF file.
        var pdfPrint = new PdfPrint("license-owner", "license-key");
        var status = pdfPrint.Print("output.pdf");
        Console.WriteLine($"Printed: {status}");
    }
}

Imports PdfPrintingNet
Imports System

Class Program
    Shared Sub Main()
        ' Step 1: Produce the PDF with another library (PDFPrinting.NET cannot).
        ' Step 2: Print the existing PDF file.
        Dim pdfPrint = New PdfPrint("license-owner", "license-key")
        Dim status = pdfPrint.Print("output.pdf")
        Console.WriteLine($"Printed: {status}")
    End Sub
End Class

Imports PdfPrintingNet
Imports System

Class Program
    Shared Sub Main()
        ' Step 1: Produce the PDF with another library (PDFPrinting.NET cannot).
        ' Step 2: Print the existing PDF file.
        Dim pdfPrint = New PdfPrint("license-owner", "license-key")
        Dim status = pdfPrint.Print("output.pdf")
        Console.WriteLine($"Printed: {status}")
    End Sub
End Class

After (IronPDF)：

// NuGet: Install-Package IronPdf
using IronPdf;
using System;

class Program
{
    static void Main()
    {
        IronPdf.License.LicenseKey = "YOUR-LICENSE-KEY";

        var renderer = new ChromePdfRenderer();
        string html = "<html><body><h1>Hello World</h1></body></html>";
        var pdf = renderer.RenderHtmlAsPdf(html);
        pdf.SaveAs("output.pdf");
        Console.WriteLine("PDF created successfully");
    }
}

// NuGet: Install-Package IronPdf
using IronPdf;
using System;

class Program
{
    static void Main()
    {
        IronPdf.License.LicenseKey = "YOUR-LICENSE-KEY";

        var renderer = new ChromePdfRenderer();
        string html = "<html><body><h1>Hello World</h1></body></html>";
        var pdf = renderer.RenderHtmlAsPdf(html);
        pdf.SaveAs("output.pdf");
        Console.WriteLine("PDF created successfully");
    }
}

Imports IronPdf
Imports System

Class Program
    Shared Sub Main()
        IronPdf.License.LicenseKey = "YOUR-LICENSE-KEY"

        Dim renderer As New ChromePdfRenderer()
        Dim html As String = "<html><body><h1>Hello World</h1></body></html>"
        Dim pdf = renderer.RenderHtmlAsPdf(html)
        pdf.SaveAs("output.pdf")
        Console.WriteLine("PDF created successfully")
    End Sub
End Class

Imports IronPdf
Imports System

Class Program
    Shared Sub Main()
        IronPdf.License.LicenseKey = "YOUR-LICENSE-KEY"

        Dim renderer As New ChromePdfRenderer()
        Dim html As String = "<html><body><h1>Hello World</h1></body></html>"
        Dim pdf = renderer.RenderHtmlAsPdf(html)
        pdf.SaveAs("output.pdf")
        Console.WriteLine("PDF created successfully")
    End Sub
End Class

因为PDFPrinting.NET根本不能撰写PDF，迁移不是一对一的类替换——而是在采用一种新能力。IronPDF的 ChromePdfRenderer.RenderHtmlAsPdf() 返回一个可以操作的 PdfDocument (水印、合并、安全性) 在使用 SaveAs() 保存之前。通过利用基于Chromium的引擎，IronPDF能够高保真地复制现代CSS和JavaScript的渲染。请参阅 HTML 转 PDF 文档，了解全面的示例。

示例 2：URL 到 PDF 的转换

之前 (PDFPrinting.NET)： 没有 WebPageToPdfConverter 类 — PDFPrinting.NET 不下载或渲染网页。必须使用一个单独的库首先将URL捕获为PDF；然后，PDFPrinting.NET可以打印生成的文件：

// NuGet: Install-Package PdfPrintingNet
using PdfPrintingNet;
using System;

class Program
{
    static void Main()
    {
        // Step 1: Capture the URL with another library (PDFPrinting.NET cannot).
        // Step 2: Print the resulting PDF.
        var pdfPrint = new PdfPrint("license-owner", "license-key");
        var status = pdfPrint.Print("webpage.pdf");
        Console.WriteLine($"Printed: {status}");
    }
}

// NuGet: Install-Package PdfPrintingNet
using PdfPrintingNet;
using System;

class Program
{
    static void Main()
    {
        // Step 1: Capture the URL with another library (PDFPrinting.NET cannot).
        // Step 2: Print the resulting PDF.
        var pdfPrint = new PdfPrint("license-owner", "license-key");
        var status = pdfPrint.Print("webpage.pdf");
        Console.WriteLine($"Printed: {status}");
    }
}

Imports PdfPrintingNet
Imports System

Class Program
    Shared Sub Main()
        ' Step 1: Capture the URL with another library (PDFPrinting.NET cannot).
        ' Step 2: Print the resulting PDF.
        Dim pdfPrint As New PdfPrint("license-owner", "license-key")
        Dim status = pdfPrint.Print("webpage.pdf")
        Console.WriteLine($"Printed: {status}")
    End Sub
End Class

Imports PdfPrintingNet
Imports System

Class Program
    Shared Sub Main()
        ' Step 1: Capture the URL with another library (PDFPrinting.NET cannot).
        ' Step 2: Print the resulting PDF.
        Dim pdfPrint As New PdfPrint("license-owner", "license-key")
        Dim status = pdfPrint.Print("webpage.pdf")
        Console.WriteLine($"Printed: {status}")
    End Sub
End Class

After (IronPDF)：

// NuGet: Install-Package IronPdf
using IronPdf;
using System;

class Program
{
    static void Main()
    {
        IronPdf.License.LicenseKey = "YOUR-LICENSE-KEY";

        var renderer = new ChromePdfRenderer();
        string url = "https://www.example.com";
        var pdf = renderer.RenderUrlAsPdf(url);
        pdf.SaveAs("webpage.pdf");
        Console.WriteLine("PDF from URL created successfully");
    }
}

// NuGet: Install-Package IronPdf
using IronPdf;
using System;

class Program
{
    static void Main()
    {
        IronPdf.License.LicenseKey = "YOUR-LICENSE-KEY";

        var renderer = new ChromePdfRenderer();
        string url = "https://www.example.com";
        var pdf = renderer.RenderUrlAsPdf(url);
        pdf.SaveAs("webpage.pdf");
        Console.WriteLine("PDF from URL created successfully");
    }
}

Imports IronPdf
Imports System

Module Program
    Sub Main()
        IronPdf.License.LicenseKey = "YOUR-LICENSE-KEY"

        Dim renderer As New ChromePdfRenderer()
        Dim url As String = "https://www.example.com"
        Dim pdf = renderer.RenderUrlAsPdf(url)
        pdf.SaveAs("webpage.pdf")
        Console.WriteLine("PDF from URL created successfully")
    End Sub
End Module

Imports IronPdf
Imports System

Module Program
    Sub Main()
        IronPdf.License.LicenseKey = "YOUR-LICENSE-KEY"

        Dim renderer As New ChromePdfRenderer()
        Dim url As String = "https://www.example.com"
        Dim pdf = renderer.RenderUrlAsPdf(url)
        pdf.SaveAs("webpage.pdf")
        Console.WriteLine("PDF from URL created successfully")
    End Sub
End Module

IronPDF 使用单个 ChromePdfRenderer 类处理 HTML 字符串和 URL，RenderUrlAsPdf() 在一次调用中处理网页捕获。在我们的教程中了解更多信息。

示例 3：页眉和页脚

**之前（PDFPrinting.NET）：**PDFPrinting.NET无法创建页眉或页脚——它不从HTML或其他源生成PDF，也不提供页眉/页脚组成API。如果您的PDF已经包含了它们，该库可以打印它：

// NuGet: Install-Package PdfPrintingNet
using PdfPrintingNet;
using System;

class Program
{
    static void Main()
    {
        // Headers/footers must already be baked into the PDF.
        var pdfPrint = new PdfPrint("license-owner", "license-key");
        pdfPrint.Print("report.pdf");
        Console.WriteLine("PDF with pre-existing headers/footers printed");
    }
}

// NuGet: Install-Package PdfPrintingNet
using PdfPrintingNet;
using System;

class Program
{
    static void Main()
    {
        // Headers/footers must already be baked into the PDF.
        var pdfPrint = new PdfPrint("license-owner", "license-key");
        pdfPrint.Print("report.pdf");
        Console.WriteLine("PDF with pre-existing headers/footers printed");
    }
}

Imports PdfPrintingNet
Imports System

Module Program
    Sub Main()
        ' Headers/footers must already be baked into the PDF.
        Dim pdfPrint As New PdfPrint("license-owner", "license-key")
        pdfPrint.Print("report.pdf")
        Console.WriteLine("PDF with pre-existing headers/footers printed")
    End Sub
End Module

Imports PdfPrintingNet
Imports System

Module Program
    Sub Main()
        ' Headers/footers must already be baked into the PDF.
        Dim pdfPrint As New PdfPrint("license-owner", "license-key")
        pdfPrint.Print("report.pdf")
        Console.WriteLine("PDF with pre-existing headers/footers printed")
    End Sub
End Module

After (IronPDF)：

// NuGet: Install-Package IronPdf
using IronPdf;
using IronPdf.Rendering;
using System;

class Program
{
    static void Main()
    {
        IronPdf.License.LicenseKey = "YOUR-LICENSE-KEY";

        var renderer = new ChromePdfRenderer();
        renderer.RenderingOptions.HtmlHeader = new HtmlHeaderFooter()
        {
            HtmlFragment = "<div style='text-align:center'>Company Report</div>"
        };
        renderer.RenderingOptions.HtmlFooter = new HtmlHeaderFooter()
        {
            HtmlFragment = "<div style='text-align:center'>Page {page} of {total-pages}</div>"
        };
        string html = "<html><body><h1>Document Content</h1></body></html>";
        var pdf = renderer.RenderHtmlAsPdf(html);
        pdf.SaveAs("report.pdf");
        Console.WriteLine("PDF with headers/footers created");
    }
}

// NuGet: Install-Package IronPdf
using IronPdf;
using IronPdf.Rendering;
using System;

class Program
{
    static void Main()
    {
        IronPdf.License.LicenseKey = "YOUR-LICENSE-KEY";

        var renderer = new ChromePdfRenderer();
        renderer.RenderingOptions.HtmlHeader = new HtmlHeaderFooter()
        {
            HtmlFragment = "<div style='text-align:center'>Company Report</div>"
        };
        renderer.RenderingOptions.HtmlFooter = new HtmlHeaderFooter()
        {
            HtmlFragment = "<div style='text-align:center'>Page {page} of {total-pages}</div>"
        };
        string html = "<html><body><h1>Document Content</h1></body></html>";
        var pdf = renderer.RenderHtmlAsPdf(html);
        pdf.SaveAs("report.pdf");
        Console.WriteLine("PDF with headers/footers created");
    }
}

Imports IronPdf
Imports IronPdf.Rendering
Imports System

Module Program
    Sub Main()
        IronPdf.License.LicenseKey = "YOUR-LICENSE-KEY"

        Dim renderer As New ChromePdfRenderer()
        renderer.RenderingOptions.HtmlHeader = New HtmlHeaderFooter() With {
            .HtmlFragment = "<div style='text-align:center'>Company Report</div>"
        }
        renderer.RenderingOptions.HtmlFooter = New HtmlHeaderFooter() With {
            .HtmlFragment = "<div style='text-align:center'>Page {page} of {total-pages}</div>"
        }
        Dim html As String = "<html><body><h1>Document Content</h1></body></html>"
        Dim pdf = renderer.RenderHtmlAsPdf(html)
        pdf.SaveAs("report.pdf")
        Console.WriteLine("PDF with headers/footers created")
    End Sub
End Module

Imports IronPdf
Imports IronPdf.Rendering
Imports System

Module Program
    Sub Main()
        IronPdf.License.LicenseKey = "YOUR-LICENSE-KEY"

        Dim renderer As New ChromePdfRenderer()
        renderer.RenderingOptions.HtmlHeader = New HtmlHeaderFooter() With {
            .HtmlFragment = "<div style='text-align:center'>Company Report</div>"
        }
        renderer.RenderingOptions.HtmlFooter = New HtmlHeaderFooter() With {
            .HtmlFragment = "<div style='text-align:center'>Page {page} of {total-pages}</div>"
        }
        Dim html As String = "<html><body><h1>Document Content</h1></body></html>"
        Dim pdf = renderer.RenderHtmlAsPdf(html)
        pdf.SaveAs("report.pdf")
        Console.WriteLine("PDF with headers/footers created")
    End Sub
End Module

IronPDF 使用 HtmlHeaderFooter 对象，具有一个接受完整 HTML 的 HtmlFragment 属性，允许用 CSS 进行丰富的样式化。占位符如 {page} 和 {total-pages} 在渲染时被替换。

关键迁移说明

页眉/页脚占位符是IronPDF的独有功能

PDFPrinting.NET根本没有页眉或页脚创建API，因此没有占位符语法需要迁移。IronPDF支持 {page} 和 {total-pages} 占位符在 HtmlHeaderFooter.HtmlFragment 内：

//IronPDFplaceholders
"Page {page} of {total-pages}"

//IronPDFplaceholders
"Page {page} of {total-pages}"

加载然后打印模式

PDFPrinting.NET 直接将文件路径传递给 Print(); IronPDF首先加载文档：

// PDFPrinting.NET: Direct path to Print()
pdfPrint.Print("document.pdf");

// IronPDF: Load first, then operate
var pdf = PdfDocument.FromFile("document.pdf");
pdf.Print();

// PDFPrinting.NET: Direct path to Print()
pdfPrint.Print("document.pdf");

// IronPDF: Load first, then operate
var pdf = PdfDocument.FromFile("document.pdf");
pdf.Print();

' PDFPrinting.NET: Direct path to Print()
pdfPrint.Print("document.pdf")

' IronPDF: Load first, then operate
Dim pdf = PdfDocument.FromFile("document.pdf")
pdf.Print()

' PDFPrinting.NET: Direct path to Print()
pdfPrint.Print("document.pdf")

' IronPDF: Load first, then operate
Dim pdf = PdfDocument.FromFile("document.pdf")
pdf.Print()

打印设置迁移

PDFPrinting.NET 使用 PdfPrint 上的属性;IronPDF使用一个设置对象：

// PDFPrinting.NET: Properties on PdfPrint
pdfPrint.Copies = 2;
pdfPrint.Duplex = true;

// IronPDF: Settings object
var settings = new PrintSettings
{
    NumberOfCopies = 2,
    DuplexMode = System.Drawing.Printing.Duplex.Vertical
};
pdf.Print(settings);

// PDFPrinting.NET: Properties on PdfPrint
pdfPrint.Copies = 2;
pdfPrint.Duplex = true;

// IronPDF: Settings object
var settings = new PrintSettings
{
    NumberOfCopies = 2,
    DuplexMode = System.Drawing.Printing.Duplex.Vertical
};
pdf.Print(settings);

' PDFPrinting.NET: Properties on PdfPrint
pdfPrint.Copies = 2
pdfPrint.Duplex = True

' IronPDF: Settings object
Dim settings As New PrintSettings With {
    .NumberOfCopies = 2,
    .DuplexMode = System.Drawing.Printing.Duplex.Vertical
}
pdf.Print(settings)

' PDFPrinting.NET: Properties on PdfPrint
pdfPrint.Copies = 2
pdfPrint.Duplex = True

' IronPDF: Settings object
Dim settings As New PrintSettings With {
    .NumberOfCopies = 2,
    .DuplexMode = System.Drawing.Printing.Duplex.Vertical
}
pdf.Print(settings)

迁移后的新功能

迁移到IronPDF后，您将获得 PDFPrinting.NET 无法提供的功能：

PDF 合并

var pdf1 = PdfDocument.FromFile("document1.pdf");
var pdf2 = PdfDocument.FromFile("document2.pdf");
var merged = PdfDocument.Merge(pdf1, pdf2);
merged.SaveAs("merged.pdf");

var pdf1 = PdfDocument.FromFile("document1.pdf");
var pdf2 = PdfDocument.FromFile("document2.pdf");
var merged = PdfDocument.Merge(pdf1, pdf2);
merged.SaveAs("merged.pdf");

Dim pdf1 = PdfDocument.FromFile("document1.pdf")
Dim pdf2 = PdfDocument.FromFile("document2.pdf")
Dim merged = PdfDocument.Merge(pdf1, pdf2)
merged.SaveAs("merged.pdf")

Dim pdf1 = PdfDocument.FromFile("document1.pdf")
Dim pdf2 = PdfDocument.FromFile("document2.pdf")
Dim merged = PdfDocument.Merge(pdf1, pdf2)
merged.SaveAs("merged.pdf")

水印

pdf.ApplyWatermark("<h2 style='color:red;'>CONFIDENTIAL</h2>");

pdf.ApplyWatermark("<h2 style='color:red;'>CONFIDENTIAL</h2>");

pdf.ApplyWatermark("<h2 style='color:red;'>CONFIDENTIAL</h2>")

pdf.ApplyWatermark("<h2 style='color:red;'>CONFIDENTIAL</h2>")

密码保护

pdf.SecuritySettings.UserPassword = "userpassword";
pdf.SecuritySettings.OwnerPassword = "ownerpassword";

pdf.SecuritySettings.UserPassword = "userpassword";
pdf.SecuritySettings.OwnerPassword = "ownerpassword";

pdf.SecuritySettings.UserPassword = "userpassword"
pdf.SecuritySettings.OwnerPassword = "ownerpassword"

pdf.SecuritySettings.UserPassword = "userpassword"
pdf.SecuritySettings.OwnerPassword = "ownerpassword"

文本提取

string text = pdf.ExtractAllText();

string text = pdf.ExtractAllText();

Dim text As String = pdf.ExtractAllText()

Dim text As String = pdf.ExtractAllText()

生成然后打印工作流程

using IronPDF，您可以在一个工作流程中生成 PDF 并打印：

var renderer = new ChromePdfRenderer();
var pdf = renderer.RenderHtmlAsPdf("<h1>Invoice</h1>");
pdf.Print("Invoice Printer");

var renderer = new ChromePdfRenderer();
var pdf = renderer.RenderHtmlAsPdf("<h1>Invoice</h1>");
pdf.Print("Invoice Printer");

Dim renderer As New ChromePdfRenderer()
Dim pdf = renderer.RenderHtmlAsPdf("<h1>Invoice</h1>")
pdf.Print("Invoice Printer")

Dim renderer As New ChromePdfRenderer()
Dim pdf = renderer.RenderHtmlAsPdf("<h1>Invoice</h1>")
pdf.Print("Invoice Printer")

跨平台打印

PDFPrinting.NET 仅适用于 Windows。IronPDF可跨平台运行：

Windows

pdf.Print("HP LaserJet");

pdf.Print("HP LaserJet");

pdf.Print("HP LaserJet")

pdf.Print("HP LaserJet")

Linux

// Requires CUPS (Common Unix Printing System)
// Install: apt-get install cups
pdf.Print("HP_LaserJet");  // CUPS uses underscores instead of spaces

// Requires CUPS (Common Unix Printing System)
// Install: apt-get install cups
pdf.Print("HP_LaserJet");  // CUPS uses underscores instead of spaces
