您可以覆盖页面的render方法以捕获服务器端的HTML源代码.

protected override void Render(HtmlTextWriter writer)
{
    // setup a TextWriter to capture the markup
    TextWriter tw = new StringWriter();
    HtmlTextWriter htw = new HtmlTextWriter(tw);

    // render the markup into our surrogate TextWriter
    base.Render(htw);

    // get the captured markup as a string
    string pageSource = tw.ToString();

    // render the markup into the output stream verbatim
    writer.Write(pageSource);

    // remove the viewstate field from the captured markup
    string viewStateRemoved = Regex.Replace(pageSource,
        "<input type=\"hidden\" name=\"__VIEWSTATE\" id=\"__VIEWSTATE\" value=\".*?\" />",
        "", RegexOptions.IgnoreCase);

    // the page source, without the viewstate field, is in viewStateRemoved
    // do what you like with it
}
