我想使用直接输入发送键。我能够发送按键。但是我不知道如何发送按键释放以避免保持按键被按下。
这是我的代码:
struct INPUT
{
public UInt32 type;
public ushort wVk;
public ushort wScan;
public UInt32 dwFlags;
public UInt32 time;
public UIntPtr dwExtraInfo;
public UInt32 uMsg;
public ushort wParamL;
public ushort wParamH;
}
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 StrokeW()
{
INPUT[] InputData = new INPUT[1];
ushort ScanCode = 0x11;
InputData[0].type = 1;
InputData[0].wScan = (ushort)ScanCode;
InputData[0].dwFlags = (uint)SendInputFlags.KEYEVENTF_SCANCODE;
SendInput(1, InputData, Marshal.SizeOf(InputData[0]));
}
注意:我在 DirectInput 应用程序中尝试使用 SendInput API 模拟键盘,但无法使其工作
