c# 中在Windows服务内怎么调用WndProc(ref Message m)检测U盘插入信息？
或者哪位大神有相应的方法在Windows服务内部监测底层信息？

要使用WndProc方法来检测U盘的插入情况，在C#中可以使用Win32 API。以下是一个简单的示例，展示了如何实现这一功能：

using System;
using System.Runtime.InteropServices;

class Program
{
    [DllImport("user32.dll")]
    private static extern IntPtr SetWindowsHookEx(int idHook, HookProc lpfn, IntPtr hMod, uint dwThreadId);

    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    private static extern bool UnhookWindowsHookEx(IntPtr hhk);

    [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    private static extern IntPtr CallNextHookEx(IntPtr hhk, int nCode, IntPtr wParam, IntPtr lParam);

    [DllImport("kernel32.dll", CharSet = CharSet.Auto)]
    private static extern IntPtr GetModuleHandle(string lpModuleName);

    [StructLayout(LayoutKind.Sequential)]
    public struct MSG
    {
        public IntPtr hWnd;
        public int msg;
        public IntPtr wParam;
        public IntPtr lParam;
    }

    [UnmanagedFunctionPointer(CallingConvention.Winapi)]
    private delegate IntPtr HookProc(int nCode, IntPtr wParam, IntPtr lParam);

    private const int WM_COMMAND = 0x112;
    private const int WM_LBUTTONDOWN = 0x0201;
    private const int WM_RBUTTONDOWN = 0x0202;
    private const int WM_MBUTTONDOWN = 0x0204;
    private const int WM_CONTEXTMENU = 0x0208;
    private const int WM_MOUSEMOVE = 0x0205;
