C#: How to execute a HTTP request using sockets?

Question

I am trying to make a HTTP request using sockets. My code is as follows:

using System;
using System.Net;
using System.Net.Sockets;
using System.

The minimum requirement for a HTTP request is "GET / HTTP/1.0\r\n\r\n" (if removing the Host is allowed). But in SNARL, you must input the content-length (what I most heard).

So,

        Socket sck = new Socket(AddressFamily.InterNetwork,SocketType.Stream, ProtocolType.Tcp);

        sck.Connect(ip, port);
        sck.Send(Encoding.UTF8.GetBytes("THE HTTP REQUEST HEADER"));
        Console.WriteLine("SENT");
        string message = null;
        byte[] bytesStored = new byte[sck.ReceiveBufferSize];
        int k1 = sck.Receive(bytesStored);
        for (int i = 0; i < k1; i++)
        {
            message = message + Convert.ToChar(bytesStored[i]).ToString();
        }
        Console.WriteLine(message); // PRINT THE RESPONSE

I tested on several sites and it works perfectly. If it didn't work, then you should fix it by adding more header (most likely solution).
