服务器

public class TcpServer : MonoBehaviour {
   public  Button button;
    Thread serverThread;
    Socket serverSocket;
   // Use this for initialization
   void Start ()
    {
        button.onClick.AddListener(StartSever);
    }

    private void StartSever()
    {
        //定义侦听端口
        IPEndPoint ipEnd = new IPEndPoint(IPAddress.Any, 8889);
        serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
        serverSocket.Bind(ipEnd);
        serverSocket.Listen(10);
        Debug.Log("等待连接。。。");
        serverThread = new Thread(ServerThread);
        serverThread.Start();
    }

    private void ServerThread()
    {
        //一旦接受连接，创建一个客户端
        Socket client = serverSocket.Accept();
        IPEndPoint ipEndClient = (IPEndPoint)client.RemoteEndPoint;
        Debug.Log("已连接" + ipEndClient.Address + ipEndClient.Port);
        while (true)
        {
            Thread.Sleep(100);
            //接收数据
            byte[] recv1 = new byte[1024];
            if (client.Available <= 0) continue;
            int count1 = client.Receive(recv1);
            Debug.Log("客户端："+Encoding.UTF8.GetString(recv1, 0, count1));

            //发送数据
            string welcome = "我是服务器" ;
            byte[] data = new byte[1024];
            data = Encoding.UTF8.GetBytes(welcome);
            client.Send(data, data.Length, SocketFlags.None);
        }
    }

    private void OnDestroy()
    {
        if (serverThread != null)
        {
            serverThread.Abort();
        }
        if (serverSocket!=null)
        {
            serverSocket.Close();
            serverSocket = null;
        }
    }
}

客户端

public class TcpClient : MonoBehaviour {
  public  Button client;
    Socket clientSocket;
    Thread clientThread;

  // Use this for initialization
  void Start () {
        client.onClick.AddListener(StartClient);
    }

    private void StartClient()
    {
       //服务器地址
        IPAddress ip = IPAddress.Parse("192.168.10.99");
        IPEndPoint ipEnd = new IPEndPoint(ip, 8889);
        clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
        clientSocket.Connect(ipEnd);
        clientThread = new Thread(ClientThread);
        clientThread.Start();
    }

    private void ClientThread()
    {
        while (true)
        {
            Thread.Sleep(100);
            //发送数据
            string msg = "哈喽，我是客户端";
            byte[] msgBytes = new byte[1024];
            msgBytes = Encoding.UTF8.GetBytes(msg);
            clientSocket.Send(msgBytes, msgBytes.Length, SocketFlags.None);

            //接收数据
            byte[] recvMsg = new byte[1024];
            if (clientSocket.Available <= 0) continue;
            int count = clientSocket.Receive(recvMsg);
            Debug.Log("服务器：" + Encoding.UTF8.GetString(recvMsg, 0, count));
        }
    }

    private void OnDestroy()
    {
        if (clientSocket!=null)
        {
            clientSocket.Close();
            clientSocket = null;
        }
        if (clientThread!=null)
        {
            clientThread.Abort();
        }
    }
