我有我的WinForms浏览器控件的3个上下文菜单。WinForm浏览器控件哪个元素被右键点击?

BrowserImages,BrowserLinks和BrowserDefault。你猜 - - 映像是正确的,当文档的空白区域是正确的

  • 链接点击 当链接
  • 和图像是正确的单击时,显示将显示

    1. 默认加载点击。

    当DocumentCompleted被激发我添加Document_ContextMenuShowing事件 - 该代码是:

    /// <summary> 
        /// Displays the Correct Context Menu for the element that is being right clicked on 
        /// </summary> 
        /// <param name="sender"> 
        /// HTMLDocument: The content of the web browser when the right click was detected. 
        /// </param> 
        /// <param name="e"> 
        /// HtmlElementEventArgs: Used for getting the location of the mouse so we know where to display the Context Menu 
        /// </param> 
        void Document_ContextMenuShowing(object sender, HtmlElementEventArgs e) 
        { 
         var res = (HtmlDocument)sender; 
    
         if (res.ActiveElement.InnerHtml.ToLowerInvariant().Contains("img")) 
         { 
          cmsBrowserImages.Show(e.ClientMousePosition.X, e.ClientMousePosition.Y); 
         } 
         else if (res.ActiveElement.InnerHtml.ToLowerInvariant().Contains("href")) 
         { 
          cmsBrowserLinks.Show(e.ClientMousePosition.X, e.ClientMousePosition.Y); 
         } 
         else 
         { 
          cmsBrowserDefault.Show(e.ClientMousePosition.X, e.ClientMousePosition.Y); 
         } 
        } 
    

    是否还有更好的,更强大的(更好的工作)的方式来做到这一点? C#代码首选,但VB.Net将beok,很容易重写。

    感谢
