新线程中的WebBrowser控件

您必须创建一个STA线程来泵送消息循环。对于像WebBrowser这样的ActiveX组件，这是唯一的好客环境。否则，您将不会获得documentCompleted事件。一些示例代码：

private void runBrowserThread(Uri url) {    var th = new Thread(() => {        var br = new WebBrowser();        br.documentCompleted += browser_documentCompleted;        br.Navigate(url);        Application.Run();    });    th.SetApartmentState(ApartmentState.STA);    th.Start();}void browser_documentCompleted(object sender, WebBrowserdocumentCompletedEventArgs e) {    var br = sender as WebBrowser;    if (br.Url == e.Url) {        Console.WriteLine("Natigated to {0}", e.Url);        Application.ExitThread();   // Stops the thread    }}
