`，，客户端（C#语言）：，`

csharp，using System;，using System.Net.Sockets;，using System.Text;，，class Program {，    static void Main() {，        TcpClient client = new TcpClient();，        client.Connect("127.0.0.1", 8080);，        NetworkStream stream = client.GetStream();，        byte[] data = Encoding.ASCII.GetBytes("Hello Server!");，        stream.Write(data, 0, data.Length);，        data = new byte[256];，        String responseData = String.Empty;，        Int32 bytes = stream.Read(data, 0, data.Length);，        responseData = Encoding.ASCII.GetString(data, 0, bytes);，        Console.WriteLine("Received: {0}", responseData);，        stream.Close();，        client.Close();，    }，}，
