C#

Hi all,
I have one windows form with C#. I want to show PDF file to be shown on that page which is on server, but I am not able to do so because it gives me messege that the page can not be displayed. But I am able to browse that image file from my local system as I have shared that file on from server to my system.
Code to show file
WebBrowser1.Navigate(@'file://webserver\UserDocs\abc.jpg');

I think this forward and backward slash does not make issue because if same i am typing in my local browser it works but not from my app.

Thanks in advamce

What I have tried:

Code to show file
