您可以为此选择evopdf。示例代码：http ://www.evopdf.com/demo/default.aspx ：

  protected void convertToPdfButton_Click(object sender, EventArgs e)
  {
  // Create a HTML to PDF converter object with default settings
  HtmlToPdfConverter htmlToPdfConverter = new HtmlToPdfConverter();

  // Set license key received after purchase to use the converter in licensed mode
  // Leave it not set to use the converter in demo mode
  htmlToPdfConverter.LicenseKey = "4W9+bn19bn5ue2B+bn1/YH98YHd3d3c=";

  // Set HTML Viewer width in pixels which is the equivalent in converter of the browser window width
  htmlToPdfConverter.HtmlViewerWidth = int.Parse(htmlViewerWidthTextBox.Text);

  // Set HTML viewer height in pixels to convert the top part of a HTML page 
  // Leave it not set to convert the entire HTML
  if (htmlViewerHeightTextBox.Text.Length > 0)
      htmlToPdfConverter.HtmlViewerHeight = int.Parse(htmlViewerHeightTextBox.Text);

  // Set PDF page size which can be a predefined size like A4 or a custom size in points 
  // Leave it not set to have a default A4 PDF page
  htmlToPdfConverter.PdfDocumentOptions.PdfPageSize = SelectedPdfPageSize();

  // Set PDF page orientation to Portrait or Landscape
  // Leave it not set to have a default Portrait orientation for PDF page
  htmlToPdfConverter.PdfDocumentOptions.PdfPageOrientation = SelectedPdfPageOrientation();

  // Set the maximum time in seconds to wait for HTML page to be loaded 
  // Leave it not set for a default 60 seconds maximum wait time
  htmlToPdfConverter.NavigationTimeout = int.Parse(navigationTimeoutTextBox.Text);

  // Set an adddional delay in seconds to wait for JavaScript or AJAX calls after page load completed
  // Set this property to 0 if you don't need to wait for such asynchcronous operations to finish
  if (conversionDelayTextBox.Text.Length > 0)
      htmlToPdfConverter.ConversionDelay = int.Parse(conversionDelayTextBox.Text);

  // The buffer to receive the generated PDF document
  byte[] outPdfBuffer = null;

  if (convertUrlRadioButton.Checked)
  {
      string url = urlTextBox.Text;

      // Convert the HTML page given by an URL to a PDF document in a memory buffer
      outPdfBuffer = htmlToPdfConverter.ConvertUrl(url);
  }
  else
  {
      string htmlString = htmlStringTextBox.Text;
      string baseUrl = baseUrlTextBox.Text;

      // Convert a HTML string with a base URL to a PDF document in a memory buffer
      outPdfBuffer = htmlToPdfConverter.ConvertHtml(htmlString, baseUrl);
  }

  // Send the PDF as response to browser

  // Set response content type
  Response.AddHeader("Content-Type", "application/pdf");

  // Instruct the browser to open the PDF file as an attachment or inline
  Response.AddHeader("Content-Disposition", String.Format("{0}; filename=Getting_Started.pdf; size={1}",
      openInlineCheckBox.Checked ? "inline" : "attachment", outPdfBuffer.Length.ToString()));

  // Write the PDF document buffer to HTTP response
  Response.BinaryWrite(outPdfBuffer);

  // End the HTTP response and stop the current page processing
  Response.End();
}
