如何将HTML转换为PDF？

在 .NET 应用程序中，将 HTML 转换为 PDF 是一项常见的任务。 对于更复杂的场景，请参考HTML 渲染设置和像素级完美渲染指南。 IronPDF 还支持HTML 文件转 PDF以及HTML ZIP 文件处理。

// PM> Install-Package IronPdf

using IronPdf;

var Renderer = new IronPdf.ChromePdfRenderer();
// Render HTML string as a PDF document and save it
Renderer.RenderHtmlAsPdf("<h1>Test HTML with images</h1>").SaveAs("test_image.pdf");

/****** Advanced ******/

// Render HTML and external assets into a PDF
// BasePath is used to resolve relative paths to assets like images and styles
var PDF = Renderer.RenderHtmlAsPdf("<img src='icons/iron.png'>", @"C:\site\assets\");
PDF.SaveAs("html-with-assets.pdf");

// PM> Install-Package IronPdf

using IronPdf;

var Renderer = new IronPdf.ChromePdfRenderer();
// Render HTML string as a PDF document and save it
Renderer.RenderHtmlAsPdf("<h1>Test HTML with images</h1>").SaveAs("test_image.pdf");

/****** Advanced ******/

// Render HTML and external assets into a PDF
// BasePath is used to resolve relative paths to assets like images and styles
var PDF = Renderer.RenderHtmlAsPdf("<img src='icons/iron.png'>", @"C:\site\assets\");
PDF.SaveAs("html-with-assets.pdf");

// Open a PDF file from disk into a FileStream
using (FileStream pdfStream = new FileStream(pdfFile, FileMode.Open, FileAccess.Read))
{
    f.OpenPdf(pdfStream);

    if (f.PageCount > 0)
    {
        // Set conversion options
        f.WordOptions.Format = SautinSoft.PdfFocus.CWordOptions.eWordDocument.Docx;
        f.WordOptions.RenderMode = SautinSoft.PdfFocus.CWordOptions.eRenderMode.Flowing;

        // Convert the PDF to a Word document and store it in docxStream
        int res = f.ToWord(docxStream);

        // Save the DOCX to disk if conversion was successful
        if (res == 0)
        {
            string docxFile = Path.ChangeExtension(pdfFile, ".docx");
            File.WriteAllBytes(docxFile, docxStream.ToArray());
            System.Diagnostics.Process.Start(docxFile);
        }
    }
