Direct Rest Call To Google Api

Question

Hi, I am trying to get Calendar list from my  Google account using WebClient class. It is throwing 401 unauthorized error. My login credentials are correct but can't figure out what is wrong in my code. Here the code I am using to access Google Calendar
Api. Please someone also tell me how to  use auth token as I know how to generate token but don't know how to use it in Webclient Api Class. I searched everywhere in Google but can't find a single example of making direct REST call to google api. 
var content = "";
try
var url = "https://www.googleapis.com/calendar/v3/users/me/calendarList";
var synClient = new WebClient();
//string credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes(userName + “:” + passWord)); this one did not work.
string credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes("use" + ":" + "pass"));
synClient.Headers[HttpRequestHeader.Authorization] = "Basic" + credentials;
content = synClient.DownloadString(url);
Console.WriteLine(content.ToString());
}catch(WebException e)
Console.WriteLine(e.Message+" "+e.StackTrace);

Please check out the documentation
here. It explains how to use it. It has a form to test requests:
HTTP request
GET https://www.googleapis.com/calendar/v3/users/me/calendarList
https://developers.google.com/google-apps/calendar/v3/reference/calendarList/list#examples
https://developers.google.com/google-apps/calendar/firstapp
You could using API directly too: http://www.codeproject.com/Articles/64474/How-to-Read-the-Google-Calendar-in-C
