wb.Url = new Uri("http://www.baidu.com");

wb.DocumentCompleted+=new WebBrowserDocumentCompletedEventHandler(wb_DocumentCompleted);

}

private void wb_DocumentCompleted(object sender, EventArgs e)//这个就是当网页载入完毕后要进行的操作

这个就是当网页载入完毕后要进行的操作

webbrowser等待页面加载完毕

while (webBrowser1.IsBusy)
{
StartKiller();
MessageBox.Show("程序忙，请稍后！", "提示");

}

或者(不能用在线程中)

while (webBrowser1.ReadyState == WebBrowserReadyState.Complete)
{
StartKiller();
MessageBox.Show("程序忙，请稍后！", "提示");

}
