我同時運行服務器應用程序和客戶端應用程序，但客戶端無法發送消息到服務器？

Question

我是新來的套接字編程，現在我想有一個聊天應用程序，客戶端是模擬器在我的電腦和服務器是現在我的電腦上的C＃應用​​程序。我使用「127.0.0.1」爲客戶端設置了服務器IP。我同時運行服務器應用程序和客戶端應用程序，但客戶端無法向服務器發送消息。什麼是錯誤？ 這是服務器側：

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

namespace serverConsol 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      TcpListener serverSocket = new TcpListener(8888); 
      int requestCount = 0; 
      TcpClient clientSocket = default(TcpClient); 
      serverSocket.Start(); 
      Console.WriteLine(" >> Server Started"); 
      clientSocket = serverSocket.AcceptTcpClient(); 
      Console.WriteLine(" >> Accept connection from client"); 
      requestCount = 0; 

      while ((true)) 
      { 
       try 
       { 
        requestCount = requestCount + 1; 
        NetworkStream networkStream = clientSocket.GetStream(); 
        byte[] bytesFrom = new byte[10025]; 
        networkStream.Read(bytesFrom, 0, (int)clientSocket.ReceiveBufferSize); 
        string dataFromClient = System.Text.Encoding.ASCII.GetString(bytesFrom); 
        dataFromClient = dataFromClient.Substring(0, dataFromClient.IndexOf("$")); 
        Console.WriteLine(" >> Data from client - " + dataFromClient); 
        string serverResponse = "Last Message from client" + dataFromClient; 
        Byte[] sendBytes = Encoding.ASCII.GetBytes(serverResponse); 
        networkStream.Write(sendBytes, 0, sendBytes.Length); 
        networkStream.Flush(); 
        Console.WriteLine(" >> " + serverResponse); 
       } 
       catch (Exception ex) 
       { 
        Console.WriteLine(ex.ToString()); 
       } 
      } 

      clientSocket.Close(); 
      serverSocket.Stop(); 
      Console.WriteLine(" >> exit"); 
      Console.ReadLine(); 
     } 
    } 
}
