Proxy Authentication required

webservice

Dear Team,

I had created a .net windows application which is consuming a webservice for transfering datas to a remote server through internet. Webservice is REST architecture. It is working in some sites but in others I am getting an error message from Webresponse as Proxy authentication required. In those site they are using a specific proxy to access internet. But When I am testing this webservice in PostMan (Google tool) I am able to access that webservice but through my c#.net application I am not able to.

Can anybody suggest me a solution for this.
