Simple C# .NET 4.5 HTTPClient Request Using Basic Auth and Proxy

SimpleHttpClient.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net.Http;
using System.Net;


namespace HTTP_Test
{
    class program
    {
        static void Main()
        {
            Task t = new Task(HTTP_GET);
            t.Start();
            Console.ReadLine();
        }

        static async void HTTP_GET()
        {
            var TARGETURL = "http://en.wikipedia.org/";

            HttpClientHandler handler = new HttpClientHandler()
            {
                Proxy = new WebProxy("http://127.0.0.1:8888"),
                UseProxy = true,
            };

            Console.WriteLine("GET: + " + TARGETURL);

            // ... Use HttpClient.            
            HttpClient client = new HttpClient(handler);

            var byteArray = Encoding.ASCII.GetBytes("username:password1234");
            client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray));

            HttpResponseMessage response = await client.GetAsync(TARGETURL);
            HttpContent content = response.Content;

            // ... Check Status Code                                
            Console.WriteLine("Response StatusCode: " + (int)response.StatusCode);

            // ... Read the string.
            string result = await content.ReadAsStringAsync();

            // ... Display the result.
            if (result != null &&
            result.Length >= 50)
            {
                Console.WriteLine(result.Substring(0, 50) + "...");
            }
        }
    }
}

Not sure what gives but for what ever reason creating the task and running it in main with t.start() does nothing. I don't get any errors it just stops when it hits the closing {} of Main(string[] args). The only thing different I added was user input on user name and password and I added an encryption method .

So I have the Main(string[] args then I have the following

` public async Task EncodePass(string password)
{

        byte[] bytes = Encoding.Unicode.GetBytes(password);
        byte[] inArray = HashAlgorithm.Create("SHA1").ComputeHash(bytes);
        return Convert.ToBase64String(inArray);
    }`

Then I have
`static async void HTTP_GET()
{

}`

THANK YOU MAN!

Thank you very much.

Thank you very much, you saved my day

thankkk youuuu

It took me a while to find out how to encode the username and password into the authorization header, your code saved me a lot of trouble, thanks!
