在Unity3D上进行TCP Client的创建与通讯

简介

Unity3D版本： 2018.3.0f2 Personal
Visual Studio版本：2017

在Unity3D上连接TCP Server建立通讯
建立通讯后进行双向数据传输

代码

创建文件TCPUDPSocket.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.IO;
using System.Net.Sockets;
using System.Text;

public class TCPUDPSocket : MonoBehaviour
{
    NetworkStream sendStream;
    TcpClient client;
    bool flag = false;
    public void Start_TCPClient(string ip, int port)
    {
        client = new TcpClient(ip, port);
        sendStream = client.GetStream();
        flag = true;
    }

    public void Close_TCPClient()
    {
        sendStream.Close();
        client.Close();
        flag = false;
    }

    public void Write_TCPClient(string data)
    {
        if (flag == false)
            return;
        byte[] sendBytes = Encoding.Default.GetBytes(data);
        sendStream.Write(sendBytes, 0, sendBytes.Length);
    }

    public string Read_TCPClient()
    {
        if (flag == false)
            return "";
        byte[] readbyte = new byte[sendStream.Length];
        sendStream.Read(readbyte, 0, (int)sendStream.Length);
        return Encoding.ASCII.GetString(readbyte);
    }
    // Start is called before the first frame update
    void Start()
    {
        Start_TCPClient("192.168.199.231",2333);
    }

    // Update is called once per frame
    void Update()
    {
        
    }

   
}

根据需要可以进行发送与接收函数的调用，函数功能很简单，看名字就知道
