客户端

using Microsoft.VisualBasic.Logging;
using System.Net.Sockets;
using System.Text;namespace TcpClientDemo
{public partial class Form1 : Form{public Form1(){InitializeComponent();}TcpClient tcpClient = new TcpClient();/// <summary>/// 连接服务端/// </summary>/// <param name="sender"></param>/// <param name="e"></param>private void connect_Click(object sender, EventArgs e){if (!tcpClient.Connected){tcpClient.Connect(IP.Text, int.Parse(PORT.Text));//开启线程一直读取数据Task.Run(() =>{while (true){NetworkStream networkStream = tcpClient.GetStream();if (networkStream != null){byte[] datas = new byte[1024];networkStream.Read(datas, 0, datas.Length);this.BeginInvoke(new Action(() =>{log.Text = Encoding.UTF8.GetString(datas);}));}}});}}/// <summary>/// 发送数据/// </summary>/// <param name="sender"></param>/// <param name="e"></param>private void send_Click(object sender, EventArgs e){NetworkStream networkStream = tcpClient.GetStream();if (networkStream != null){byte[] datas = Encoding.UTF8.GetBytes(log.Text);networkStream.Write(datas, 0, datas.Length);}}private void Form1_Load(object sender, EventArgs e){IP.Text = "127.0.0.1";PORT.Text = "8899";}}
}

服务端

using Microsoft.VisualBasic.Logging;
using System.Net;
using System.Net.Sockets;
using System.Text;namespace TcpSeverDemo
{public partial class Form1 : Form{public Form1(){InitializeComponent();}//监听类TcpListener listener = null;//客户端TcpClient handler = null;NetworkStream stream = null;bool isrun = false;/// <summary>/// 打开/// </summary>/// <param name="sender"></param>/// <param name="e"></param>private void openServer_Click(object sender, EventArgs e){if (IP.Text.Trim().Length < 9 && Port.Text.Trim().Length == 0){MessageBox.Show("IP和端口无效");return;}listener = new TcpListener(IPAddress.Parse(IP.Text), int.Parse(Port.Text));listener.Start();isrun = true;}private void send_Click(object sender, EventArgs e){if (stream != null){byte[] buffer = Encoding.UTF8.GetBytes(log.Text);//load已经连接,可以直接发送stream.Write(buffer, 0, buffer.Length);}}private void Form1_Load(object sender, EventArgs e){IP.Text = "127.0.0.1";Port.Text = "9800";try{Task.Run(() =>{while (true){if (isrun && listener != null){//用来接收handler = listener.AcceptTcpClient();//创建网络流 已经连接stream = handler.GetStream();byte[] buffer = new byte[1024];if (stream != null){stream.Read(buffer, 0, buffer.Length);this.BeginInvoke(new Action(() =>{log.Text = Encoding.UTF8.GetString(buffer);}));}}Thread.Sleep(50);}});}catch (Exception){}}/// <summary>/// 关闭/// </summary>/// <param name="sender"></param>/// <param name="e"></param>private void Form1_FormClosing(object sender, FormClosingEventArgs e){isrun = false;if (listener != null){listener.Stop();}}}
}

串口

using Microsoft.VisualBasic.Logging;
using System.Data;
using System.IO.Ports;
using System.Text;namespace PortDemo
{public partial class Form1 : Form{public Form1(){InitializeComponent();}SerialPort serialPort = new SerialPort();private void open_Click(object sender, EventArgs e){try{if (!serialPort.IsOpen){serialPort.Open();serialPort.DataReceived += SerialPort_DataReceived;}}catch (Exception ex){log.Text = ex.Message;}}private void read_Click(object sender, EventArgs e){}private void write_Click(object sender, EventArgs e){serialPort.Write(log.Text);}private void Form1_Load(object sender, EventArgs e){//导入一些基础参数List<string> ports = SerialPort.GetPortNames().ToList();foreach (var item in ports){port.Items.Add(item);}List<int> baus = new List<int> { 9600, 115200 };foreach (var item in baus){bau.Items.Add(item);}List<int> databits = new List<int> { 6, 7, 8 };foreach (var item in databits){databit.Items.Add(item);}List<string> cks = new List<string> { "None" };foreach (var item in cks){check.Items.Add(item);}List<string> stops = new List<string> { "One" };foreach (var item in stops){stop.Items.Add(item);}try{serialPort.PortName = port.Text;serialPort.BaudRate = int.Parse(bau.Text);serialPort.Parity = Parity.None;serialPort.DataBits = int.Parse(databit.Text);serialPort.StopBits = StopBits.One;}catch (Exception ex){log.Text = ex.Message;}}private void SerialPort_DataReceived(object sender, SerialDataReceivedEventArgs e){byte[] bytes = new byte[1024];try{serialPort.Read(bytes, 0, bytes.Length);string data = Encoding.UTF8.GetString(bytes);this.Invoke(() =>{log.Text = data;});}catch (Exception ex){log.Text = ex.Message;}}}

Socket通信

using System;
using System.Net;
using System.Net.Sockets;class Program
{static void Main(){Socket listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);listener.Bind(new IPEndPoint(IPAddress.Any, 13000));listener.Listen(10);while (true){Console.WriteLine("Waiting for a connection...");Socket handler = listener.Accept();Console.WriteLine("Connected!");// 处理连接HandleClient(handler);}}private static void HandleClient(Socket client){NetworkStream stream = new NetworkStream(client);byte[] data = new byte[256];while (true){int bytes = stream.Read(data, 0, data.Length);if (bytes == 0)break;string text = Encoding.ASCII.GetString(data, 0, bytes);Console.WriteLine("Received: {0}", text);}client.Close();}
}

最简单的调用，之后会补充实际细节。这种基本不需要自己手动造轮子，除非重新开发，基本都是封装好的，会调用就可以，需要自己写的时候网上找找一堆。
