关于webBrowser的DocumentCompleted事件

Question

我用webBrowser 获取网页的代码。
用WebBrowserReadyState.Complete 判断加载完成
但好像对www.myadalliance.com这个网站没有用。
不管等多久他都不会加载完成。
  
        private void webBrowser4_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {            if (this.webBrowser4.ReadyState == WebBrowserReadyState.Complete)
            {
                
            }
              
        }望高手解答疑惑。

Answer 1

加载完成后我执行了 if (this.webBrowser4.ReadyState == WebBrowserReadyState.Complete)
            {
                MessageBox.Show("test");
            }
               

Answer 2

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)   
{   
while (webBrowser1.ReadyState != WebBrowserReadyState.Complete)   
{   
  Application.DoEvents();   
}   
}

Answer 3

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)   
{   
while (webBrowser1.ReadyState != WebBrowserReadyState.Complete)   
{   
  Application.DoEvents();   
}   
}
 这也不行。

Answer 4

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)   
{   
while (webBrowser1.ReadyState != WebBrowserReadyState.Complete)   
{   
  Application.DoEvents();   
}   
}
 这样写获取出来是多次的。

Answer 5

这个事件会触发多次，你必须使用其他条件来判断网页是否加载完毕。
参考： 自定义WebBrowser

Answer 7

webBrowser1.DocumentTitle获取标题也没有发现问题
