Question

如何从列表框中的webbrowser获取URI？此代码添加20 URI而不是1：

private void webBrowser1_DocumentCompleted(object sender, 

WebBrowserDocumentCompletedEventArgs e)
{
    radListControl1.Items.Add(webBrowser1.Url.AbsoluteUri.ToString());
}

或

private void webBrowser1_Navigated(object sender, WebBrowserNavigatedEventArgs e)
{
    radListControl1.Items.Add(webBrowser1.Url.AbsoluteUri.ToString());
}

Answer 1

 if (!radListControl1.Items.Contains(webBrowser1.Url.ToString()))
     radListControl1.Items.Add(webBrowser1.Url.ToString());

因为在单页加载中多次触发此事件...

Answer 2

您需要检查事件提供的URI与浏览器中的URI：

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
   if (e.Url.Equals(webBrowser1.Url)) 
    // this is the real one
}
