Q:WebBrowser如何讓DocumentCompleted事件執行完畢後再往下執行?
A:使用信號量,等待一下
System.Threading.AutoResetEvent obj = new System.Threading.AutoResetEvent(false); void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) ...{ obj.Set(); } private void button1_Click(object sender, EventArgs e) ...{ this.webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted); this.webBrowser1.Navigate("www.sina.com.cn"); obj.Reset(); while (obj.WaitOne(10, false) == false) ...{ Application.DoEvents(); } MessageBox.Show(""); }
