如何从默认Web浏览器中触发WebBrowserDocumentCompleted事件

Question

我尝试了两种方法：

1. wb.Navigate(Url,true);当我使用此网络浏览器时，但WebBrowserDocumentCompleted事件在页面加载后不会触发。

2. wb.Navigate(Url);当我使用此WebBrowserDocumentCompleted事件时，但是浏览器未出现在屏幕上。如何在同一时间显示外部浏览器并触发WebBrowserDocumentCompleted事件？

   private void button1_Click(object sender, EventArgs e)
   {
       System.Windows.Forms.WebBrowser wb = new System.Windows.Forms.WebBrowser();
       wb.DocumentCompleted += WebBrowserDocumentCompleted;
       wb.Visible = true;
       wb.ScrollBarsEnabled = false;
       wb.ScriptErrorsSuppressed = true;
       wb.Navigate("http://www.google.com",true);
   }
   
   private void WebBrowserDocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
   {
       if ((sender as WebBrowser).ReadyState == System.Windows.Forms.WebBrowserReadyState.Complete)
       {
           // Do what ever you want to do here when page is completely loaded.
       }
   }
