C# 如何在继续之前等待网页完成加载

Question

我正在尝试创建一个程序，通过我们的缺陷跟踪系统的 Web 界面一次克隆多个错误。如何才能等到页面完全加载后再继续？

//This is pseudo code, but this should give you an idea of what I'm trying to do.  The
//actual code uses multi-threading and all that good stuff :).
foreach (string bug in bugs)
{
    webBrowser.Navigate(new Uri(url));
    webBrowser.Document.GetElementById("product").SetAttribute("value", product);
    webBrowser.Document.GetElementById("version").SetAttribute("value", version);
    webBrowser.Document.GetElementById("commit").InvokeMember("click");

    //Need code to wait for page to load before continuing.
}

尝试 DocumentCompleted 事件:

webBrowser.DocumentCompleted +=
    new WebBrowserDocumentCompletedEventHandler(webBrowser_DocumentCompleted);

void webBrowser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    webBrowser.Document.GetElementById("product").SetAttribute("value", product);
    webBrowser.Document.GetElementById("version").SetAttribute("value", version);
    webBrowser.Document.GetElementById("commit").InvokeMember("click");
}
