c# - WebBrowserDocumentCompleted

Question

如何使正在进行的操作 WebBrowserDocumentCompleted 在单独的线程中工作。所以它不会影响主窗体（不会挂起整个应用程序）

表格1

private void bStart_Click(object sender, EventArgs e)
        {
            wb.Navigate("http://www.moswar.ru");
        }

表格2

    public void wb_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
            {
                wb = sender as WebBrowser;
                ThreadPool.QueueUserWorkItem(new WaitCallback((object unused) =>

                    {

                        if (wb.Document.GetElementById("login-email") != null)
                        {
                            wb.Document.GetElementById("login-email").InnerText = "myemail@blah.pe";
                            wb.Document.GetElementById("login-password").InnerText = "MyPassword";
                           GetElementsByClassName(new string[] { "button luxury" })[0].InvokeMember("click");
                        }


                if (e.Url.AbsoluteUri == "http://www.moswar.ru/player/" || e.Url.AbsoluteUri == "http://www.moswar.ru/player/#login")
                {
                    wb.Navigate("http://www.moswar.ru/metro/");
                }
                    }));
            //and so on .....
            }
