C# webclient and proxy server

Question

I am using a web client class in my source code for downloading a string using http.

This was working fine. However, the clients in the company are all connected now

Answer 1

byte[] data;
using (WebClient client = new WebClient())
{
    ICredentials cred;
    cred = new NetworkCredential("xmen@test.com", "mybestpassword");
    client.Proxy = new WebProxy("192.168.0.1",8000);
    client.Credentials = cred;
    string myurl="http://mytestsite.com/source.jpg";
    data = client.DownloadData(myUrl);
}

File.WriteAllBytes(@"c:\images\target.jpg", data);
