Need to support TCP connection with 4 byte ASCII header,C#

I am sending a command a user inputs over to a server through IP and port number. I do not need the code for the server side because I am just writing the command to it and then reading its response back to me. I can send everything and read response with code that i have below, however I cannot get it to read it with a 4 byte ASCII header option.

public static void Main(string[] args)

{

TcpClient tcpclnt = new TcpClient();

Console.WriteLine("Connecting.....");

tcpclnt.Connect("172.2.2.2", 8000);

NetworkStream streamToServer = tcpclnt.GetStream();

StreamReader reader = new StreamReader(streamToServer);

Console.Write("Enter the string to be transmitted : ");

string command = reader.ReadLine();

Console.WriteLine("Sending {0} to server", command);

StreamWriter sw = new StreamWriter(streamToServer);

sw.Write(command);

sw.Flush();

string response = Read(streamToServer); //calls the Read method that reads the stream and returns back the response with the 4 byte ASCII header

                        Console.WriteLine("Server: " + response);//prints the response from server

}

This right there sends the data, I am wanting a method that will be called something like this that returns the string from the server. Again it needs to be changed to work with a 4 byte ASCII header, that is what I am stuck on.

public static string Read(NetworkStream stream)

        {

this method will need to read the stream and return a string back. I have it all as one now, but will put in a while loop, so I need a method to return the string back so I can print it out in main method.

byte[] bb = new byte[4096];

int k = stm.Read(bb, 0, bb.Length);

for (int i = 0; i < k; i++)

Console.Write(Convert.ToChar(bb[i]));

}
