Question

Is it possbile to use the windows login credential for proxy authentication using C#.

I have a facebook application, which calls the facebook methods. During every facebook call, it gives an error “407: proxy authentication required”

The following code will allow the user to set the proxy :-

WebProxy oWebProxy = new System.Net.WebProxy(ProxyServer, ProxyPort);       
oWebProxy.Credentials = new NetworkCredential(ProxyUser,ProxyPassword,ProxyDomain);
oserv.Proxy = oWebProxy; 
oserv.Credentials = new NetworkCredential(theusername, thepassword); 

But, is there any other way of doing the same thing without hardcoding my company’s login credentials.

You can use :

oWebProxy.Credentials = System.Net.CredentialCache.DefaultCredentials;
