WPF封装常用的TCP、串口、Modbus、MQTT、Webapi、PLC通讯工具类

WPF封装常用通讯工具类

下面我将为您封装常用的TCP、串口、Modbus、MQTT、WebAPI和PLC通讯工具类，适用于WPF应用程序开发。

一、TCP通讯工具类

using System;
using System.Net.Sockets;
using System.Text;
using System.Threading.Tasks;public class TcpClientHelper : IDisposable
{private TcpClient _tcpClient;private NetworkStream _networkStream;private readonly object _lock = new object();public event Action<string> ReceivedData;public bool IsConnected => _tcpClient?.Connected ?? false;public async Task ConnectAsync(string ipAddress, int port){try{if (_tcpClient != null && _tcpClient.Connected)await DisconnectAsync();_tcpClient = new TcpClient();
