Question

我在互联网上搜索，主要是在这个网站上搜索，我找不到具体的例子。所以，我想要做的是覆盖Windows命令（在这种情况下，如Windows + R创建一个假的运行框）。我找到了许多有用的示例，但一次只有一个键，或者只涉及Alt，Ctrl和Shift。在这一个Windows键将被禁用，所以我可以重新分配它，但我希望它在后台工作，如这个特定的代码：

public partial class Form1 : Form
{
    // Structure contain information about low-level keyboard input event
    [StructLayout(LayoutKind.Sequential)]
    private struct KBDLLHOOKSTRUCT
    {
        public Keys key;
        public int scanCode;
        public int flags;
        public int time;
        public IntPtr extra;
    }

    //System level functions to be used for hook and unhook keyboard input
    private delegate IntPtr LowLevelKeyboardProc(int nCode, IntPtr wParam, IntPtr lParam);

    [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    private static extern IntPtr SetWindowsHookEx(int id, LowLevelKeyboardProc callback, IntPtr hMod, uint dwThreadId);
    [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    private static extern bool UnhookWindowsHookEx(IntPtr hook);
    [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    private static extern IntPtr CallNextHookEx(IntPtr hook, int nCode, IntPtr wp, IntPtr lp);
    [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    private static extern IntPtr GetModuleHandle(string name);
    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    private static extern short GetAsyncKeyState(Keys key);

    //Declaring Global objects
    private IntPtr ptrHook;
    private LowLevelKeyboardProc objKeyboardProcess;

    private IntPtr CaptureKey(int nCode, IntPtr wp, IntPtr lp)
    {
        if (nCode >= 0)
        {
            KBDLLHOOKSTRUCT objKeyInfo = (KBDLLHOOKSTRUCT)Marshal.PtrToStructure(lp, typeof(KBDLLHOOKSTRUCT));
            if (objKeyInfo.key == Keys.RWin || objKeyInfo.key == Keys.LWin) // Disabling Windows keys
            {
                Opacity = 1;
                return (IntPtr)1;
            }
        }
        return CallNextHookEx(ptrHook, nCode, wp, lp);
    }

    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        //Get Current Module
        ProcessModule objCurrentModule = Process.GetCurrentProcess().MainModule;
        //Assign callback function each time keyboard process
        objKeyboardProcess = new LowLevelKeyboardProc(CaptureKey);
        //Setting Hook of Keyboard Process for current module
        ptrHook = SetWindowsHookEx(13, objKeyboardProcess, GetModuleHandle(objCurrentModule.ModuleName), 0);
    }

    private void Form1_FormClosing(object sender, FormClosingEventArgs e)
    {
        e.Cancel = true;
        Opacity = 0;
    }
}

有什么想法吗？
