Webbrowser控件document_completed多次触发

问题描述：

document_complete的事件多次触发。哪个不是那么糟糕但是我正在导航的url，从来没有被完全加载。它被触发了2/3次。

The event of document_complete fires more than once. Which isn't really that bad. But the url i'm navigating to, never gets completely loaded. It gets fired like 2/3 times.

这是我的document_completed事件：

This is my document_completed event:

private void webBrowser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    if (e.Url.AbsolutePath != this.wbrowser.Url.AbsolutePath) 
        return;
    else
        string doctext = this.wbrowser.DocumentText;
}

我做错了什么？

答

您将获得一个 DocumentCompleted 每帧/ iframe事件，这就是为什么有几个。如果你没有得到最后一个，那是因为一些资源仍在加载或挂起。它可以是一个图像，一个脚本文件或一些iframe。

You will get one DocumentCompleted event per frame/iframe, that's why there are several. If you don't get the last one it's because some resource is still loading or hanging. It could be an image, a script file, or some iframe.

你最好的解决方案是添加一个超时，并继续你的程序，如果你得到最后一个 DocumentCompleted 事件，或您的超时踢。

Your best solution is to add a timeout, and continue your program if you get the last DocumentCompleted event, or your timeout kicks in.
