我的问题是“请求数据”始终为空.我不明白我在哪里放“webBrowser1.Navigate”命令.

现在我的代码如下.

private void button3_Click(object sender,EventArgs e)
{
    webBrowser1.ScriptErroRSSuppressed = true;
    WebProxy myProxy = new WebProxy();
    Uri newUri = new Uri("http://localhost:8888");
    myProxy.Address = newUri;

    Fiddler.FiddlerApplication.Startup(8888,false,false);

    List<Fiddler.Session> oAllSessions = new List<Fiddler.Session>();

    webBrowser1.Navigate("http://www.youtube.com/");
    while (webBrowser1.ReadyState != WebBrowserReadyState.Complete)
    {
        System.Windows.Forms.Application.DoEvents();
    }

    Fiddler.FiddlerApplication.BeforeRequest += delegate(Fiddler.Session oS)
    {
        Monitor.Enter(oAllSessions);
        oAllSessions.Add(oS);
        Monitor.Exit(oAllSessions);
    };

    var message = string.Join(Environment.NewLine,oAllSessions);
    MessageBox.Show(message);

    Fiddler.FiddlerApplication.Shutdown();

}

谢谢您的帮助
