Question

有谁知道，如何使用sendkeys保护将按键发送到应用程序？

我尝试了sendkeys和记事本它完美无缺，但当我运行目标应用程序并尝试我的程序时，它没有，并且在记事本中它也不起作用，当这个应用程序运行时。

我不知道如何绕过这种保护。

不明白受保护应用程序的含义是什么？

无论哪种方式，.NET框架附带的SendKeys都是有限的。你可以使用windows api：

[DllImport("user32.dll")]
private static extern UInt32 SendInput(UInt32 nInputs,[MarshalAs(UnmanagedType.LPArray, SizeConst = 1)] Input[] pInputs, Int32 cbSize);

此外，您可能希望将其他应用程序设置为前台：

[DllImport("User32.dll")]
private static extern int SetForegroundWindow(IntPtr point);

然后，您将获得应用程序主窗口句柄的过程，如下所示：

var processes = Process.GetProcessesByName(processName);
// Note that this line will get the first process with the given name:
// if there are multiple, you will only get the first, and you should
// also include a check that the array isn't empty!
var handle = processes[0].MainWindowHandle;

然后

SetForegroundwindow(handle);
SendInput(....);

如果您想将密钥发送到游戏应用程序，则需要额外的工作。大多数游戏都使用DirectX输入。简而言之，如果您需要更详细的信息，请告诉我。

用于API调用的结构和枚举：

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

[StructLayout(LayoutKind.Sequential)]
struct KeyboardInput
{
    public short wVk;      //Virtual KeyCode (not needed here)
    public short wScan;    //Directx Keycode 
    public int dwFlags;    //This tells you what is use (Keyup, Keydown..)
    public int time;
    public IntPtr dwExtraInfo;
}

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

[StructLayout(LayoutKind.Explicit)]
struct Input
{
    [FieldOffset(0)]
    public int type;
    [FieldOffset(4)]
    public MouseInput mi;
    [FieldOffset(4)]
    public KeyboardInput ki;
    [FieldOffset(4)]
    public HardwareInput hi;
}

[Flags]
public enum KeyFlag
{       
    KeyDown = 0x0000,
    ExtendedKey = 0x0001,
    KeyUp = 0x0002,
    UniCode = 0x0004,
    ScanCode = 0x0008
}
