可以在ASP.NET MVC中提供现有的HTML文件或字符串、现有的PDF文档以及PDF。 我们在下面的教程中概述了如何在您的C#项目中轻松将MVC视图转换为PDF。
ASP.NET MVC 从视图生成 PDF 教程
- 下载 ASP.NET MVC 从视图库生成 PDF
- 在 Visual Studio 中安装
- 在 ASP.NET MVC 中服务 PDF
- 提供现有 PDF 文件
- 服务现有 HTML 文件或字符串
步骤 1
1. 安装IronPDF
为了处理现有的PDF文件、HTML文件或字符串，以及在ASP.NET MVC中提供PDF，我们可以使用IronPDF的C# PDF库。 免费下载开发版，并开始以下教程。 通过它访问IronPDF DLL ZIP 文件或通过IronPDF NuGet 软件包.
Install-Package IronPdf

2. 在ASP.NET MVC中提供PDF服务
要在ASP.NET MVC中提供PDF文档需要生成一个文件结果方法。 With IronPDF, 您可以使用ASP.NET MVC 框架返回 PDF 文件。
此方法可以如下由您的控制器提供。
/**
Serve PDF in ASPNET MVC
anchor-serve-pdf-in-asp-net-mvc
**/
public FileResult GetHTMLPageAsPDF(long id) {
//Create a PDF Document
using var PDF = Renderer.RenderHtmlAsPdf("<h1>Hello IronPdf and MVC</h1>");
//return a pdf document from a view
var contentLength = PDF.BinaryData.Length;
Response.AppendHeader("Content-Length", contentLength.ToString());
Response.AppendHeader("Content-Disposition", "inline; filename=Document_" + id + ".pdf");
return File(PDF.BinaryData, "application/pdf;");
}/**
Serve PDF in ASPNET MVC
anchor-serve-pdf-in-asp-net-mvc
**/
public FileResult GetHTMLPageAsPDF(long id) {
//Create a PDF Document
using var PDF = Renderer.RenderHtmlAsPdf("<h1>Hello IronPdf and MVC</h1>");
//return a pdf document from a view
var contentLength = PDF.BinaryData.Length;
Response.AppendHeader("Content-Length", contentLength.ToString());
Response.AppendHeader("Content-Disposition", "inline; filename=Document_" + id + ".pdf");
return File(PDF.BinaryData, "application/pdf;");
}'''
'''Serve PDF in ASPNET MVC
'''anchor-serve-pdf-in-asp-net-mvc
'''*
Public Function GetHTMLPageAsPDF(ByVal id As Long) As FileResult
'Create a PDF Document
Dim PDF = Renderer.RenderHtmlAsPdf("<h1>Hello IronPdf and MVC</h1>")
'return a pdf document from a view
Dim contentLength = PDF.BinaryData.Length
Response.AppendHeader("Content-Length", contentLength.ToString())
Response.AppendHeader("Content-Disposition", "inline; filename=Document_" & id & ".pdf")
Return File(PDF.BinaryData, "application/pdf;")
End FunctionVB C#
对于更高级的示例，您可以使用 HTML 视图生成 HTML 字符串，然后将其转换为 PDF，如上图所示。
3. 提供现有的PDF文件
为了直接提供服务其他 ASP.NET 环境中的 PDF 文件此外，还可以翻译
/**
Serve Existing PDF
anchor-serve-existing-pdf-file
**/
Response.Clear();
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Disposition","attachment;filename=\"FileName.pdf\"");
// edit this line to display in browser and change the file name
Response.BinaryWrite(System.IO.File.ReadAllBytes("MyPdf.pdf"));
// gets our pdf as a byte array and then sends it to the buffer
Response.Flush();
Response.End();
/**
Serve Existing PDF
anchor-serve-existing-pdf-file
**/
Response.Clear();
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Disposition","attachment;filename=\"FileName.pdf\"");
// edit this line to display in browser and change the file name
Response.BinaryWrite(System.IO.File.ReadAllBytes("MyPdf.pdf"));
// gets our pdf as a byte array and then sends it to the buffer
Response.Flush();
Response.End();
'''
'''Serve Existing PDF
'''anchor-serve-existing-pdf-file
'''*
Response.Clear()
Response.ContentType = "application/pdf"
Response.AddHeader("Content-Disposition","attachment;filename=""FileName.pdf""")
' edit this line to display in browser and change the file name
Response.BinaryWrite(System.IO.File.ReadAllBytes("MyPdf.pdf"))
' gets our pdf as a byte array and then sends it to the buffer
Response.Flush()
Response.End()VB C#
4.服务现有 HTML 文件或字符串
/**
Serve Existing HTML File or String
anchor-serve-existing-html-file-or-string
**/
var Renderer = new IronPdf.ChromePdfRenderer();
using var PDF = Renderer.RenderHTMLFileAsPdf("Project/MyHtmlDocument.html");
// or to convert an HTML string
//var PDF = Renderer.RenderHtmlAsPdf("<h1>Hello IronPdf</h1>");
Response.Clear();
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Disposition","attachment;filename=\"FileName.pdf\"");
// edit this line to display in browser and change the file name
Response.BinaryWrite( PDF.BinaryData );
Response.Flush();
Response.End();
/**
Serve Existing HTML File or String
anchor-serve-existing-html-file-or-string
**/
var Renderer = new IronPdf.ChromePdfRenderer();
using var PDF = Renderer.RenderHTMLFileAsPdf("Project/MyHtmlDocument.html");
// or to convert an HTML string
//var PDF = Renderer.RenderHtmlAsPdf("<h1>Hello IronPdf</h1>");
Response.Clear();
Response.ContentType = "application/pdf";
Response.AddHeader("Content-Disposition","attachment;filename=\"FileName.pdf\"");
// edit this line to display in browser and change the file name
Response.BinaryWrite( PDF.BinaryData );
Response.Flush();
Response.End();
'''
'''Serve Existing HTML File or String
'''anchor-serve-existing-html-file-or-string
'''*
Dim Renderer = New IronPdf.ChromePdfRenderer()
Dim PDF = Renderer.RenderHTMLFileAsPdf("Project/MyHtmlDocument.html")
' or to convert an HTML string
'var PDF = Renderer.RenderHtmlAsPdf("<h1>Hello IronPdf</h1>");
Response.Clear()
Response.ContentType = "application/pdf"
Response.AddHeader("Content-Disposition","attachment;filename=""FileName.pdf""")
' edit this line to display in browser and change the file name
Response.BinaryWrite(PDF.BinaryData)
Response.Flush()
Response.End()VB C#
