Webbrowser is not disposing itself

问题

I am creating a WPF application. I created a usercontrol and put a back button and webbrowser. The webbrowser is for showing some Flash objects and works without a problem. However, when I click back, the program returns to previous user control but I can still hear some sound coming from webbrowser. Here is my method:

void btnClose_Click(object sender, RoutedEventArgs e)
{
    Content contentPage = new Content();
    webBrowser1.Dispose();
    this.Content = contentPage;
}

How can I dispose webbrowser? Thanks in advance

回答1:

Instead of calling Dispose, you should reset the WebBrowser.Source property:

webBrowser1.Source = null;

MSDN doc of WebBrowser.Dispose says:

This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.
