用iTextSharp将HTML转换成PDF，ASP.NET C# 代码

先去github下载源代码：https://github.com/itext/itextsharp，当前最新版本为5.5.13

解压后用vs2010打开工程文件BuildAll，生成itextsharp.xmlworker项目

生成的dll文件在src\extras\itextsharp.xmlworker\bin\Debug_woDrawing目录中

在自已的项目引入itextsharp.dll 和 itextsharp.xmlworker.dll

写一个简单的Helper类

using System;
using System.IO;

using iTextSharp.text;
using iTextSharp.text.pdf;
using iTextSharp.tool.xml;

public class PDFHelper {
    public static void Html2Pdf(string html, string filename) {
            using (Stream fs = new FileStream(filename, FileMode.Create)) {
                using (Document doc = new Document(PageSize.A4)) {

                    PdfWriter writer = PdfWriter.GetInstance(doc, fs);
                    doc.Open();

                    using (StringReader sr = new StringReader(html)) {
                        XMLWorkerHelper.GetInstance().ParseXHtml(writer, doc, sr);
                    }

                    doc.Close();
                    
                }
            }
        }

    }

调用：

string file = Server.MapPath("test.pdf");
string html = "<div style=\"font-family:'Microsoft YaHei';\"><a href='#last'>底部</a><h1 style='padding:1000px 0'>Hello World! 中文<br/><br/><br/><br/><br/><br/></h1><a name='last'>锚链接</a><div style='color:#0a0'>测试内容</div></div>";

PDFHelper.Html2Pdf(html, file);

注意：要设置中文字体才能显示中文，默认字体不会显示中文
