推荐答案

以下是解决方案: 调用WebView的UnLoaded事件 -webView.Unloaded + = webView_UnLoaded;

Here is the solution: Invoke the UnLoaded event of WebView - webView.Unloaded += webView_UnLoaded;

然后在webView_UnLoaded事件处理程序中更改Webview的源: 这是我的代码:

Then change the source of the webview in webView_UnLoaded event handler: Here is my code:

private void webView_UnLoaded(object sender, RoutedEventArgs e)
    {
        WebView webView = (WebView)sender;
        webView.Source = new Uri(" ");
    }
