在asp.net使用WebBrowser抓取ajax信息问题

donghang

贴上代码
public class WebBrowserCrawler
    {
        private WebBrowser _webbrowder;
        private string _result { get; set; }
        private string _path { get; set; }

        public string GetReult(string url)
        {
            _path = url;

            var mThread = new Thread(FatchDataToResult);
            mThread.SetApartmentState(ApartmentState.STA);
            mThread.Start();
            mThread.Join();

            return _result;

        }

        private void FatchDataToResult()
        {

                _webbrowder = new WebBrowser();
                _webbrowder.DocumentCompleted += _webbrowder_DocumentCompleted;
                _webbrowder.Url = new Uri(_path);

                while (_webbrowder.ReadyState != WebBrowserReadyState.Complete)
                {
                    Application.DoEvents();
                }
                _webbrowder.Dispose();



        }

        void _webbrowder_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
                HtmlDocument doc = (sender as WebBrowser).Document;
                HtmlElement uinList = doc.GetElementById("list_uin");
                _result = uinList.OuterHtml;

        }
    }



调用
WebBrowserCrawler wc = new WebBrowserCrawler();
string str = wc.GetReult(url);



在VS里面测试运行正常，挂到IIS6.0上面就出问题。网页一直加载无反应。
错误信息：
