C# WinUSB设备的读写操作示例

using System;using System.IO;using System.Threading;namespace WinUSBExample{    class Program    {        static void Main(string[] args)        {            // GUID of the WinUSB device            Guid deviceGuid = new Guid("PUT_YOUR_DEVICE_GUID_HERE");            // Find the device            var devices = WinUsbHelper.GetConnectedDevices(deviceGuid);            if (devices.Count == 0)            {                Console.WriteLine("No WinUSB device found");                return;            }            // Open the device            var device = devices[0];            device.Open();            // Write data to the device            byte[] writeData = { 0x01, 0x02, 0x03 };            device.Write(writeData);            Console.WriteLine("Data written to device: " + BitConverter.ToString(writeData).Replace("-", ""));            // Read data from the device            byte[] readData = new byte[3];            device.Read(readData);            Console.WriteLine("Data read from device: " + BitConverter.ToString(readData).Replace("-", ""));            // Close the device            device.Close();            Console.WriteLine("Press any key to exit");            Console.ReadKey();        }    }}

在上面的示例中，我们首先使用WinUsbHelper.GetConnectedDevices方法查找连接的WinUSB设备，并打开第一个找到的设备。然后我们使用device.Write方法向设备写入数据，使用device.Read方法从设备读取数据，最后关闭设备连接。

请注意，您需要将PUT_YOUR_DEVICE_GUID_HERE替换为您的WinUSB设备的GUID。您还需要定义WinUsbHelper类来帮助您操作WinUSB设备，这里是一个简单的实现示例：

using System;using System.Collections.Generic;using System.Management;public static class WinUsbHelper{    public static List<WinUsbDevice> GetConnectedDevices(Guid deviceGuid)    {        var devices = new List<WinUsbDevice>();        using (var searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PnPEntity WHERE DeviceID LIKE 'USB%'"))        {            foreach (var device in searcher.Get())            {                var deviceId = device.GetPropertyValue("DeviceID").ToString();                if (deviceId.Contains(deviceGuid.ToString("B")))                {                    devices.Add(new WinUsbDevice(deviceId));                }            }        }        return devices;    }}public class WinUsbDevice{    private string deviceId;    public WinUsbDevice(string deviceId)    {        this.deviceId = deviceId;    }    public void Open()    {        // Implement device open logic here    }    public void Write(byte[] data)    {        // Implement write logic here    }    public void Read(byte[] data)    {        // Implement read logic here    }    public void Close()    {        // Implement device close logic here    }}

请注意，上面的WinUsbHelper类是一个简单的示例实现，您可能需要根据您的实陗际情况对其进行调整和扩展。
