PDFmyURL最近也发布了一个。net组件，用于网页/ HTML到PDF的转换。它有一个非常友好的用户界面，例如:

PDFmyURL pdf = new PDFmyURL("yourlicensekey");
pdf.ConvertURL("http://www.example.com", Application.StartupPath + @"\example.pdf");

这是我整理的。net中HTML到PDF转换的选项列表(有些是免费的，有些是付费的)

如果上面的选项都帮不了你，你可以搜索NuGet包: https://www.nuget.org/packages?q=html+pdf

如果你已经使用itextsharp dll，不需要添加第三方dll的(插件)，我认为你正在使用htmlworker而不是它使用xmlworker，你可以很容易地将你的html转换为pdf。 一些css不能工作，他们是受支持的css 完整的解释与示例参考点击这里

        MemoryStream memStream = new MemoryStream();
        TextReader xmlString = new StringReader(outXml);
        using (Document document = new Document())
        {
            PdfWriter writer = PdfWriter.GetInstance(document, memStream);
            //document.SetPageSize(iTextSharp.text.PageSize.A4);
            document.Open();
            byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(outXml);
            MemoryStream ms = new MemoryStream(byteArray);
            XMLWorkerHelper.GetInstance().ParseXHtml(writer, document, ms, System.Text.Encoding.UTF8);
            document.Close();
        }

        Response.ContentType = "application/pdf";
        Response.AddHeader("content-disposition", "attachment;filename=" + filename + ".pdf");
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.BinaryWrite(memStream.ToArray());
        Response.End();
        Response.Flush();

与Winnovative HTML到PDF转换器，您可以转换HTML字符串在单行

byte[] outPdfBuffer = htmlToPdfConverter.ConvertHtml(htmlString, baseUrl);

基URL用于解析HTML字符串中相对URL引用的图像。另外，你也可以在HTML中使用完整的url，或者使用src="data:image/png"作为图像标签嵌入图像。

在回答'fubaar'用户对Winnovative转换器的评论时，有必要进行更正。转换器不使用IE作为渲染引擎。它实际上不依赖于任何安装的软件，并且渲染与WebKit引擎兼容。

不是直接将HTML解析为PDF，而是可以创建HTML页面的位图，然后将位图插入到PDF中，例如使用iTextSharp。

这是一个代码如何获得一个URL的位图。我在这里找到了它，如果我找到了源，我会链接它。

public System.Drawing.Bitmap HTMLToImage(String strHTML)
{
    System.Drawing.Bitmap myBitmap = null;

    System.Threading.Thread myThread = new System.Threading.Thread(delegate()
    {
        // create a hidden web browser, which will navigate to the page
        System.Windows.Forms.WebBrowser myWebBrowser = new System.Windows.Forms.WebBrowser();
        // we don't want scrollbars on our image
        myWebBrowser.ScrollBarsEnabled = false;
        // don't let any errors shine through
        myWebBrowser.ScriptErrorsSuppressed = true;
        // let's load up that page!    
        myWebBrowser.Navigate("about:blank");

        // wait until the page is fully loaded
        while (myWebBrowser.ReadyState != System.Windows.Forms.WebBrowserReadyState.Complete)
            System.Windows.Forms.Application.DoEvents();

        myWebBrowser.Document.Body.InnerHtml = strHTML;

        // set the size of our web browser to be the same size as the page
        int intScrollPadding = 20;
        int intDocumentWidth = myWebBrowser.Document.Body.ScrollRectangle.Width + intScrollPadding;
        int intDocumentHeight = myWebBrowser.Document.Body.ScrollRectangle.Height + intScrollPadding;
        myWebBrowser.Width = intDocumentWidth;
        myWebBrowser.Height = intDocumentHeight;
        // a bitmap that we will draw to
        myBitmap = new System.Drawing.Bitmap(intDocumentWidth - intScrollPadding, intDocumentHeight - intScrollPadding);
        // draw the web browser to the bitmap
        myWebBrowser.DrawToBitmap(myBitmap, new System.Drawing.Rectangle(0, 0, intDocumentWidth - intScrollPadding, intDocumentHeight - intScrollPadding));
    });
    myThread.SetApartmentState(System.Threading.ApartmentState.STA);
    myThread.Start();
    myThread.Join();

    return myBitmap;
}

最好的工具，我发现和用于生成javascript和样式渲染视图或html页面的PDF是phantomJS。

下载带有rasterize.js函数的.exe文件，在示例文件夹的exe根目录下找到，并放入解决方案。

它甚至允许你下载文件在任何代码，而不打开该文件，它也允许下载文件时，风格和特别是jquery应用。

以下代码生成PDF文件:

public ActionResult DownloadHighChartHtml()
{
    string serverPath = Server.MapPath("~/phantomjs/");
    string filename = DateTime.Now.ToString("ddMMyyyy_hhmmss") + ".pdf";
    string Url = "http://wwwabc.com";

    new Thread(new ParameterizedThreadStart(x =>
    {
        ExecuteCommand(string.Format("cd {0} & E: & phantomjs rasterize.js {1} {2} \"A4\"", serverPath, Url, filename));
                           //E: is the drive for server.mappath
    })).Start();

    var filePath = Path.Combine(Server.MapPath("~/phantomjs/"), filename);

    var stream = new MemoryStream();
    byte[] bytes = DoWhile(filePath);

    Response.ContentType = "application/pdf";
    Response.AddHeader("content-disposition", "attachment;filename=Image.pdf");
    Response.OutputStream.Write(bytes, 0, bytes.Length);
    Response.End();
    return RedirectToAction("HighChart");
}



private void ExecuteCommand(string Command)
{
    try
    {
        ProcessStartInfo ProcessInfo;
        Process Process;

        ProcessInfo = new ProcessStartInfo("cmd.exe", "/K " + Command);

        ProcessInfo.CreateNoWindow = true;
        ProcessInfo.UseShellExecute = false;

        Process = Process.Start(ProcessInfo);
    }
    catch { }
}


private byte[] DoWhile(string filePath)
{
    byte[] bytes = new byte[0];
    bool fail = true;

    while (fail)
    {
        try
        {
            using (FileStream file = new FileStream(filePath, FileMode.Open, FileAccess.Read))
            {
                bytes = new byte[file.Length];
                file.Read(bytes, 0, (int)file.Length);
            }

            fail = false;
        }
        catch
        {
            Thread.Sleep(1000);
        }
    }

    System.IO.File.Delete(filePath);
    return bytes;
}
