C# CAN通讯与电脑通讯代码

在C#中，CAN（Controller Area Network）通信通常通过.NET Framework下的System.Transactions.CAN库或者第三方库如NCan、FreeRTOS.NET等来实现。以下是简化的示例代码，展示了如何使用NCan库连接到CAN总线并发送接收数据：

using NCan;
using System;

public class CANExample
{
    private ICanBus can; // 使用NCan库的主CAN接口

    public CANExample()
    {
        try
        {
            can = new CanBus(CanControllerType.Can0); // 创建一个与CAN0控制器关联的对象
            can.Start(); // 启动CAN通信

            // 发送数据
            var message = new CanMessage(0x123, new byte[] { 0x45, 0x67 }); // ID 0x123, 数据 { 0x45, 0x67 }
            can.SendMessage(message);

            // 接收数据
            while (true)
            {
                CanMessage receivedMessage = can.Receive();
                if (receivedMessage != null)
                {
                    Console.WriteLine($"Received message with ID: {receivedMessage.Id}, Data: {BitConverter.ToString(receivedMessage.Data)}");
                }
            }

        }
        catch (Exception ex)
        {
            Console.WriteLine($"Error in CAN communication: {ex.Message}");
        }
    }
}
