C # WinForm uses the WebBrowser control, does not eject the new page, only opens in the current window __web

1. Remember to import class library: Using System.ComponentModel;
2. Modify the properties of the WebBrowser:
Allowwebbrowserdrop set to False
Webbrowsershortcutsenabled set to False
Iswebbrowsercontextmenuenabled set to False

3. The specific setup code is as follows:

       private void Webbrowser1_newwindow (object sender, CancelEventArgs e)
       {
                e.cancel = true;
       }        
 
        private void Webbrowser1_documentcompleted (object sender, WebBrowserDocumentCompletedEventArgs e)
        {            
            foreach (HtmlElement links in This.webBrowser1.Document.Links)
            {
                links. SetAttribute ("Target", "_self");
            }            
            foreach (HtmlElement form in this.webBrowser1.Document.Forms)
            {
                form. SetAttribute ("Target", "_self");
            }
