using System;

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，我們首先使用WinUsbHelper.GetConnectedDevices方法查找連接的WinUSB設備，并打開第一個找到的設備。然后我們使用device.Write方法向設備寫入數據，使用device.Read方法從設備讀取數據，最后關閉設備連接。

請注意，您需要將PUT_YOUR_DEVICE_GUID_HERE替換為您的WinUSB設備的GUID。您還需要定義WinUsbHelper類來幫助您操作WinUSB設備，這里是一個簡單的實現示例：

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
    }
}

請注意，上面的WinUsbHelper類是一個簡單的示例實現，您可能需要根據您的實陗際情況對其進行調整和擴展。
