tcp socket buffer problem

you need to loop through until complete buffer is read. use concatenation operator to store the value in str to preserv complete data. In the end use SetText

kindly help out with the code
thanks

use this function to read the buffer

private byte[] GetSocketData(Socket socket, int lenght)
{
    byte[] data = new byte[lenght];  
    int size = lenght;
    var total = 0;
    var dataleft = size;

    while (total < size) 
    {
        var recv = socket.Receive(data, total, dataleft, SocketFlags.None);
        if (recv == 0)
        {
            data = null;
            break;
        }
        total += recv;
        dataleft -= recv;
    }
    return data;
}

i tried but did not get the desired result. request to help out . sharing whole code to check.
private void btnStart_Click(object sender, EventArgs e)
        {
            m_stripport = Convert.ToInt32(textBox_ip.Text);
            //IPAddress ip = IPAddress.Parse("127.0.0.1");
            IPAddress ip = IPAddress.Parse("10.0.0.102");
            serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            serverSocket.Bind(new IPEndPoint(ip, m_stripport));
            serverSocket.Listen(10);

            Thread myThread = new Thread(ListenClientConnect);
            myThread.Start();
            Console.ReadLine();
           
        }
        private void ListenClientConnect()
        {
            while (true)
            {
                Socket clientSocket = serverSocket.Accept();
                clientSocket.Send(Encoding.UTF8.GetBytes("Server Say Hello"));
                //clientSocket.Send(Encoding.ASCII.GetBytes("Server Say Hello"));
                Thread receiveThread = new Thread(ReceiveMessage);
                receiveThread.Start(clientSocket);
            }
        }
       
        private void ReceiveMessage(object clientSocket)
        {
            Socket myClientSocket = (Socket)clientSocket;
            while (true)
            {
                try
                {
                    int receiveNumber = myClientSocket.Receive(result);
                    Anal_Cmd(result, receiveNumber);
                }
                catch (Exception ex)
                {
                    Console.WriteLine(ex.Message);
                    myClientSocket.Shutdown(SocketShutdown.Both);
                    myClientSocket.Close();
                    break;
                }

            }

        }

        private void Anal_Cmd(byte[] recv, int nrecv)
        {
            String str;
            str = Encoding.ASCII.GetString(recv);
            SetText(str);

      }
thanks in advance. will be a great help .
