如何在.NET中模拟按下按钮?
我可以轻松地使用AutoHotKey:
#Persistent
SetTimer,PressTheKey,1000
Return
PressTheKey:
Send, {F5}
Return
任何应用程序都会知道按钮被按下了(就像我按下了按钮一样)。我尝试过这样做:
[DllImport("user32.dll", SetLastError = true)]
public static extern uint SendInput(uint nInputs, INPUT[] pInputs, int cbSize);
或:
[DllImport("user32.dll")]
static extern void keybd_event(byte bVk, byte bScan, uint dwFlags, int dwExtraInfo);
或使用Windows输入模拟器(https://inputsimulator.codeplex.com/):
inputSimulator.Keyboard.KeyDown(VirtualKeyCode.VK_H)
他们都在记事本或其他一些应用程序中工作,但他们从未在我的全屏游戏中工作过。知道如何实现它吗?我想要一个在系统级别全局模拟点击的解决方案。

有一个名为Interceptor的lib是Windows键盘驱动程序的包装器,但是有一些限制 - 即不支持win8或更高版本 - 并且它的工作似乎停止了(11个月)以前)。如果它符合您的需求,请查看它。
我已经通过DirectInput API了解了有哪些方法可以做到这一点 - 至于这是否是我不确定的情况。我已经使用了Interceptor
几次,当时它可以满足我的需求。
希望这有帮助

我了解到我的应用程序正在使用DirectInput(感谢Gabe)。这让我更专注于SendInput,我设法发送了一个" A"像我这样的应用程序的关键:
// A = 30
keyboardDirectInput.Press(30);
所有关键代码均可在此处获取:https://msdn.microsoft.com/en-us/library/windows/desktop/bb321074%28v=vs.85%29.aspx
KeyboardDirectInput类:
public class KeyboardDirectInput
{
[DllImport("user32.dll")]
static extern UInt32 SendInput(UInt32 nInputs, [MarshalAs(UnmanagedType.LPArray, SizeConst = 1)] INPUT[] pInputs, Int32 cbSize);
public void Press(VirtualKeys key)
{
INPUT[] InputData = new INPUT[2];
InputData[0].type = (int)InputType.INPUT_KEYBOARD;
InputData[0].ki.wScan = (short)key;
InputData[0].ki.dwFlags = (int)KEYEVENTF.SCANCODE;
InputData[1].type = (int)InputType.INPUT_KEYBOARD;
InputData[1].ki.wScan = (short)key;
InputData[1].ki.dwFlags = (int)(KEYEVENTF.KEYUP | KEYEVENTF.SCANCODE);
if (SendInput(2, InputData, Marshal.SizeOf(InputData[1])) == 0)
{
Logger.GetInstance().Warn("SendInput failed (CODE {0})", Marshal.GetLastWin32Error());
}
