我编写了程序以将输入发送到游戏和桌面应用程序，而不是从键盘获取输入。结果如下：

Windows 7（32 位）：在游戏和桌面应用程序中完美运行。

Windows 8（64 位）：不能在游戏中工作，但在 notepad.exe 中工作。

那么为什么它不适用于win 8？

这是代码：

      [StructLayout(LayoutKind.Sequential)]
    struct MOUSEINPUT
    {
        public int dx;
        public int dy;
        public uint mouseData;
        public uint dwFlags;
        public uint time;
        public IntPtr dwExtraInfo;
    }

    [StructLayout(LayoutKind.Sequential)]
    struct KEYBDINPUT
    {
        public ushort wVk;
        public ushort wScan;
        public uint dwFlags;
        public uint time;
        public IntPtr dwExtraInfo;
    }

    [StructLayout(LayoutKind.Sequential)]
    struct HARDWAREINPUT
    {
        public int uMsg;
        public short wParamL;
        public short wParamH;
    }

    [StructLayout(LayoutKind.Explicit)]
    struct MouseKeybdHardwareInputUnion
    {
        [FieldOffset(0)]
        public MOUSEINPUT mi;

        [FieldOffset(0)]
        public KEYBDINPUT ki;

        [FieldOffset(0)]
        public HARDWAREINPUT hi;
    }

    [StructLayout(LayoutKind.Sequential)]
    struct INPUT
    {
        public uint type;
        public MouseKeybdHardwareInputUnion mkhi;
    }
    enum SendInputFlags
    {
        KEYEVENTF_EXTENDEDKEY = 0x0001,
        KEYEVENTF_KEYUP = 0x0002,
        KEYEVENTF_UNICODE = 0x0004,
        KEYEVENTF_SCANCODE = 0x0008,
    }

    [DllImport("user32.dll")]
    static extern UInt32 SendInput(UInt32 nInputs, [MarshalAs(UnmanagedType.LPArray, SizeConst = 1)] INPUT[] pInputs, Int32 cbSize);
    public static void StrokeKey(ushort codeOfKey)
    {
        INPUT[] InputData = new INPUT[1];
        ushort ScanCode = codeOfKey;
        InputData[0].type = 1;
        InputData[0].mkhi.ki.wScan = (ushort)ScanCode;
        InputData[0].mkhi.ki.dwFlags = (uint)SendInputFlags.KEYEVENTF_SCANCODE;

        if (SendInput(1, InputData, Marshal.SizeOf(InputData[0])) == 0)
        {
            String blad = "SendInput failed with code: " + Marshal.GetLastWin32Error().ToString();
            System.Diagnostics.Debug.WriteLine(blad);
        }
    }


    public static void ReleaseKey(ushort codeOfKey)
    {
        INPUT[] InputData = new INPUT[1];
        ushort ScanCode = codeOfKey;
        InputData[0].type = 1;
        InputData[0].mkhi.ki.wScan = (ushort)ScanCode;
        InputData[0].mkhi.ki.dwFlags = (uint)SendInputFlags.KEYEVENTF_KEYUP | (uint)SendInputFlags.KEYEVENTF_SCANCODE;
        InputData[0].mkhi.ki.time = 0;
        InputData[0].mkhi.ki.dwExtraInfo = IntPtr.Zero;
        SendInput(1, InputData, Marshal.SizeOf(InputData[0]));
    }

最有可能的指针大小在 32 位上是不同的，它的大小在 64 位上是 4，它的大小是 8
