动手实现

引用库

首先，通过NuGetj将STTech.BytesIO.Tcp引用到项目中；

界面设计

客户端的界面设计如下图：

源代码

using STTech.BytesIO.Core;
using STTech.BytesIO.Tcp;
using System;
using System.Collections.Generic;
using System.Windows.Forms;

namespace Demo.BytesIO.Client
{
    public partial class Form1 : Form
    {
        private BytesClient client;
        public Form1()
        {
            InitializeComponent();
            CheckForIllegalCrossThreadCalls = false;

            client = new TcpClient() ;

            propertyGrid.SelectedObject = client;

            client.OnDataReceived += Client_OnDataReceived;
            client.OnConnectedSuccessfully += Client_OnConnectedSuccessfully;
            client.OnDisconnected += Client_OnDisconnected;
        }

        private void Client_OnDisconnected(object sender, STTech.BytesIO.Core.Entity.DisconnectedEventArgs e)
        {
            Print($"已断开({e.ReasonCode})");
        }

        private void Client_OnConnectedSuccessfully(object sender, STTech.BytesIO.Core.Entity.ConnectedSuccessfullyEventArgs e)
        {
            Print("连接成功");
        }

        private void Client_OnDataReceived(object sender, STTech.BytesIO.Core.Entity.DataReceivedEventArgs e)
        {
            Print($"收到数据：{e.Data.EncodeToString("GBK")}");
        }

        private void btnConnect_Click(object sender, EventArgs e)
        {
            client.Connect();
        }

        private void btnDisconnect_Click(object sender, EventArgs e)
        {
            client.Disconnect();
        }

        private void btnSend_Click(object sender, EventArgs e)
        {
            client.Send(tbSend.Text.GetBytes("GBK"));
        }

        private void Print(string msg)
        {
            tbRecv.AppendText($"[{DateTime.Now}] {msg}\r\n");
        }
    }
}
