  这将完美地运作

  我们需要添加带有线程的webbrowser，否则我们将得到ActiveX控件'8856f961-340a-11d0-a96b-00c04fd705a2'无法实例化，因为当前线程不在单线程单元中 . 错误

  这是我们可以让webbrowser在asp.net网页中工作的方式

  using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Web;
  using System.Threading;
  using System.Windows.Forms;
  
  /// <summary>
  /// Summary description for CustomBrowser
  /// </summary>
  public class CustomBrowser
  {
      public CustomBrowser()
      {
          //
          // TODO: Add constructor logic here
          //
      }
  
      protected string _url;
      string html = "";
      public string GetWebpage(string url)
      {
          _url = url;
          // WebBrowser is an ActiveX control that must be run in a
          // single-threaded apartment so create a thread to create the
          // control and generate the thumbnail
          Thread thread = new Thread(new ThreadStart(GetWebPageWorker));
          thread.SetApartmentState(ApartmentState.STA);
          thread.Start();
          thread.Join();
          string s = html;
          return s;
      }
  
      protected void GetWebPageWorker()
      {
          using (WebBrowser browser = new WebBrowser())
          {
              //  browser.ClientSize = new Size(_width, _height);
              browser.ScrollBarsEnabled = false;
              browser.ScriptErrorsSuppressed = true;
              browser.Navigate(_url);
  
              // Wait for control to load page
              while (browser.ReadyState != WebBrowserReadyState.Complete)
                  Application.DoEvents();
  
              html = browser.DocumentText;
  
          }
      }
  
  }
  

  在网页中

  CustomBrowser browser = new CustomBrowser();
  string s = browser.GetWebpage("http://localhost:8781/WebSite3/Default3.aspx");
  Response.Write(s);

  你想要做的是在ASP.NET中略显不正统，但这里有一个例子可以帮助你：
