How to add basic authentication header to WebRequest [duplicate]

Easy. In order to add a basic authentication to your HttpRequest you do this:

string username = "Your username";
string password = "Your password";

string svcCredentials = Convert.ToBase64String(ASCIIEncoding.ASCII.GetBytes(username + ":" + password));

request.Headers.Add("Authorization", "Basic " + svcCredentials);

In basic authentication you need to use Base64 to encode the credentials.
