How to make a GET request using the NetworkStream class?

I am trying to make a GET request using the NetworkStream class. MyWebServer does not log the request so I am assumming that request is not formatted properly.

 public void MakeRequest()
    {
        int port = 80;
        IPHostEntry host = Dns.GetHostEntry("192.168.1.152");
        IPEndPoint endPoint = new IPEndPoint(host.AddressList[0], 80);

        using (Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp))
        {
            socket.Connect(endPoint);

            using (NetworkStream ns = new NetworkStream(socket))
            {
                byte[] bytes = System.Text.Encoding.UTF8.GetBytes(@"GET /MyWebServer HTTP/1.1\r\n");
                ns.Write(bytes, 0, bytes.Length);
            }
        }
    }

First, you don't need to use Dns.GetHostEntry() for IP addresses, only hostnames:

IPEndPoint endPoint = new IPEndPoint("192.168.1.152", 80);

Second, your request is not formatted correctly. You are missing the Host header (required in HTTP 1.1), and you are missing a final \r\n at the end of the request:

byte[] bytes = System.Text.Encoding.UTF8.GetBytes(@"GET /MyWebServer HTTP/1.1\r\nHost: 192.168.1.152\r\n\r\n");

That being said, you really should be using HttpWebRequest or HttpClient instead of using NetworkStream directly, eg:

using (WebRequest Request = new WebRequest.Create("http://192.168.1.152/MyWebServer"))
{
    WebResponse Response = Request.GetResponse();
    // use Response as needed...
}


using (HttpClient Client = new HttpClient())
{
    client.BaseAddress = new Uri("http://192.168.1.152/");
    HttpResponseMessage Response = await Client.GetAsync("MyWebServer");
    // use Response as needed...
}
