C# YT88Tool获取加密狗ID的方法代码

以下是使用 C# 编写的获取加密狗 ID 的代码示例：

using System;
using System.Runtime.InteropServices;

class Program
{
    [DllImport("SynoUSB.dll", EntryPoint = "SynoGetDevCount", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.StdCall)]
    public static extern int SynoGetDevCount();

    [DllImport("SynoUSB.dll", EntryPoint = "SynoOpenDevice", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.StdCall)]
    public static extern int SynoOpenDevice(int nDevIndex);

    [DllImport("SynoUSB.dll", EntryPoint = "SynoCloseDevice", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.StdCall)]
    public static extern int SynoCloseDevice(int nHandle);

    [DllImport("SynoUSB.dll", EntryPoint = "SynoGetID", CharSet = CharSet.Ansi, CallingConvention = CallingConvention.StdCall)]
    public static extern int SynoGetID(int nHandle, int nID, [MarshalAs(UnmanagedType.LPArray)] byte[] pID);

    static void Main(string[] args)
    {
        int nCount = SynoGetDevCount();
        if (nCount <= 0)
        {
            Console.WriteLine("未找到加密狗");
            return;
        }

        int nHandle = SynoOpenDevice(0);
        if (nHandle < 0)
        {
            Console.WriteLine("打开加密狗失败");
            return;
        }

        byte[] pID = new byte[8];
        int nRet = SynoGetID(nHandle, 0, pID);
        if (nRet != 0)
        {
            Console.WriteLine("获取加密狗 ID 失败");
            SynoCloseDevice(nHandle);
            return;
        }

        string strID = BitConverter.ToString(pID).Replace("-", "");
        Console.WriteLine("加密狗 ID：" + strID);

        SynoCloseDevice(nHandle);
    }
}

请注意，此代码示例依赖于 `SynoUSB.dll` 动态链接库，需要将其置于可执行文件同一目录下。此外，由于加密狗的 ID 是一段二进制数据，因此需要将其转换为十六进制字符串进行显示。
