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。
