変数を使用してkeybd_eventを使用してアクションを実行しようとしましたが、左コントロールを解放すると2つのLControlKeyとLMenuがコンソールに書き込まれたとき、LShiftKeyはどうなりましたか？コントロールがHookCallbackで2回キャッチされました
マイコード：

const uint KEYEVENTF_EXTENDEDKEY = 0x0001;
const uint KEYEVENTF_KEYUP = 0x0002;
private static bool self = false;
private static LowLevelKeyboardProc _proc = HookCallback;
private static IntPtr _hookID = IntPtr.Zero;
public static void Main()
{
_hookID = SetHook(_proc);
Application.Run();
UnhookWindowsHookEx(_hookID);
}
public static IntPtr HookCallback(int nCode, IntPtr wParam, IntPtr lParam)
{
if (nCode >= 0 && wParam == (IntPtr)WM_KEYUP)
{
int vkCode = Marshal.ReadInt32(lParam);
var Key = (Keys)vkCode;
Console.WriteLine(Key);
if (!self && Key == Keys.LControlKey)
{
self = true;
keybd_event((int)Keys.LControlKey, (byte)MapVirtualKey((int)Keys.LControlKey, 0),
KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, 0);
self = false;
keybd_event((int)Keys.LMenu, (byte)MapVirtualKey((int)Keys.LMenu, 0),
0 | KEYEVENTF_EXTENDEDKEY, 0); //Send L-Alt down
Thread.Sleep(10);
keybd_event((int)Keys.LShiftKey, (byte)MapVirtualKey((int)Keys.LShiftKey, 0),
0 | KEYEVENTF_EXTENDEDKEY, 0);//Send L-Shift down
Thread.Sleep(10);
//Send L-Alt & L-Shift up
keybd_event((int)Keys.LShiftKey, (byte)MapVirtualKey((int)Keys.LShiftKey, 0),
KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, 0);
keybd_event((int)Keys.LMenu, (byte)MapVirtualKey((int)Keys.LMenu, 0),
KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP, 0);
}
}
return CallNextHookEx(_hookID, nCode, wParam, lParam);
}
private static IntPtr SetHook(LowLevelKeyboardProc proc)
{
using (Process curProcess = Process.GetCurrentProcess())
using (ProcessModule curModule = curProcess.MainModule)
{
return SetWindowsHookEx(WH_KEYBOARD_LL, proc,
GetModuleHandle(curModule.ModuleName), 0);
}
}

public static extern void keybd_event(byte bVk, byte bScan, uint dwFlags, int extraInfo);

感謝。
