Proxy Authentication in .NET - for external API

Question

I\'m developing a twitter messaging utility using Twitter API (twitterizer). But since I\'m within a corporate proxy, I\'m getting the error \'407 Proxy Authentication Required\

Answer 1

One of the possible programmatic solutions is to create following proxy:

IWebProxy proxy=HttpWebRequest.GetSystemWebProxy();  
proxy.Credentials = CredentialCache.DefaultCredentials;  

and then assign this to any object that make the network call and accept a proxy,e.g:

WebClient client = new WebClient();
client.proxy= proxy;
