C# WebBrowser 获得选中部分的html源码

原文: C# WebBrowser 获得选中部分的html源码

   Winform程序  
  2.0的. 需要引用Microsoft.mshtml. 
  

         
  private  
  void Form1_Load( 
  object sender, EventArgs e) 
  
        { 
  
            webBrowser1.Navigate( 
  " 
  http://www.baidu.com 
  "); 
  
            webBrowser1.DocumentCompleted +=  
  new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted); 
  
        } 
  

         
  void webBrowser1_DocumentCompleted( 
  object sender, WebBrowserDocumentCompletedEventArgs e) 
  
        { 
  
            webBrowser1.Document.MouseUp +=  
  new HtmlElementEventHandler(Document_MouseUp); 
  
        } 
  

         
  void Document_MouseUp( 
  object sender, HtmlElementEventArgs e) 
  
        { 
  
            IHTMLDocument2 document = (IHTMLDocument2)webBrowser1.Document.DomDocument; 
  
            IHTMLTxtRange htmlElem = (IHTMLTxtRange)document.selection.createRange(); 
  
             
  string s = htmlElem.htmlText; 
  
            richTextBox1.Text = s; 
  
        } 
 

 

需要看document.selection.createRange();类型 需要引用Microsoft.VisualBasic. 用Microsoft.VisualBasic.Information.TypeName(document.selection.createRange());方法查看类型.

差不多就这些了~ 不知道每次记录这些遇到的问题 能帮助别人不..- -|
