_"getting error here"_ - read [ask] and show the actual error, as wel as what you've tried. — CodeCaster, Dec 09 '21 at 16:48
Why don't you just right click (or `Ctrl+.`) on the errors, select _Quick actions and refactoring_ and add the using statement it suggests? — The2Step, Dec 09 '21 at 16:52
sir @CodeCaster showing error like : CS1061 'object' does not contain a definition for 'Write' and no accessible extension method 'Write' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) — indralove, Dec 09 '21 at 16:57

You're using the WPF WebBrowser control.

Instead of System.Windows.Controls use WinForms: using System.Windows.Forms;

Or see How can I get an HtmlElementCollection from a WPF WebBrowser and How to get HTML from WebBrowser control, cast WebBrowser.Document to the appropriate type, or host the control in your WPF window.
