How to change the HTML elements loaded by WebBrowser

Method 1: Add code to the event after the Web page is loaded, I just modified the page does not appear scroll bar, because scroll bar i rewrite.

1 #regionA function that executes a callback after the Web page is loaded (private)2 3         /// <summary>4         ///The function that executes the callback after the Web page is loaded, in which the parameters of the scrollbar are initialized5         /// </summary>6         Private voidWebbrowser1_documentcompleted (Objectsender, WebBrowserDocumentCompletedEventArgs e)7         {8             if( This. Webbrowser1.readystate = =webbrowserreadystate.complete)9             {TenHtmlElementCollection bodys= This. WebBrowser1.Document.GetElementsByTagName ("Body"); OneHtmlElement body=NULL; A                 if(Bodys. Count>0)  -body=bodys[0]; -                 if(Body! =NULL ) the                 { -                     if(body.) Style! =NULL ) -Body. Style + ="Overflow:hidden;"; -                     Else +Body. Stle ="Overflow:hidden;"; -                 } +            } +         } A         #endregion

Method 2: Modify the Documenttex content directly

1  Private voidWebbrowser1_documentcompleted (Objectsender, WebBrowserDocumentCompletedEventArgs e)2         {3             if( This. Webbrowser1.readystate = =webbrowserreadystate.complete)4             {5                 Try6                 {7                     stringStrhtml= This. Webbrowser1.documenttext;8strHTML ="here, change where you want to move.";9                      This. Webbrowser1.documenttext =strhtml; One                 } A                 Catch -                 { -                 } the  -             } -}

Method 3: Everybody says that.

This.webBrowser1.Document.Body.SetAttribute ("Scroll", "no");

Summary: Here to explain the difference between this method and the first method, the first method modified, in the rendered page right-click View source code is not see the modified content,
But you can see it in the webBrowser1.Document.Body.OuterHtml attribute.
The second method after modifying the right-click to see the source code can also be seen, about other more in-depth differences, as a rookie I still did not care,

Method 3, not very flexible, sometimes useless

I'm using the first method.
