GetAsyncKeyState隨機在發佈版本中工作

我想要捕獲按鍵（例如，ctrl + WinKey或只有逗號）。我在C＃中使用WH_KEYBOARD_LL鉤子和GetAsyncKeyState。如果我在調試器下運行它（即沒有設置斷點的調試器），它就可以正常工作。但是，如果我運行它沒有調試器，它很少工作。不調用熱鍵代碼 - 與在調試器下工作的代碼非常相似。GetAsyncKeyState隨機在發佈版本中工作

我注意到，如果我添加日誌記錄代碼，那麼它的工作原理也沒有調試器。它通常也適用於較慢的PC。

我該如何解決問題？

以下是從鉤處理器

private bool HotKeyHandler(WPARAM wParam, LPARAM lParam, WH_KEYBOARD_LL.KBDLLHOOKSTRUCT KeyInfo) { 

if ((WH_KEYBOARD_LL.GetAsyncKeyState(Keys.LWin) < 0 || WH_KEYBOARD_LL.GetAsyncKeyState(Keys.RWin) < 0)) { 
    if ((int)wParam == WH_KEYBOARD_LL.WM_KEYDOWN) { 
      if (WH_KEYBOARD_LL.GetAsyncKeyState(Keys.ControlKey) < 0) { 
       switch (KeyInfo.VkCode) { 
        case WH_KEYBOARD_LL.VK_OEM_COMMA: 
         // Some action - this doesn't work randomly ... 
        return true; 
... 
       } 
      } 

     } 
    } 
return false; 
} 


WH_KEYBOARD_LL.Initialize(HotKeyHandler); 

     public static void Initialize(Func<WPARAM, LPARAM, KBDLLHOOKSTRUCT, bool> Handler) { 
      HandlerI = Handler; 
      KeyboardHookProcedureHandle = NativeCalls.Hooks.SetWindowsHookEx(NativeCalls.Hooks.HookType.WH_KEYBOARD_LL, KeyboardLLHandler, IntPtr.Zero, 0);

     private static LRESULT KeyboardProcedure(int MustProcessMessage, WPARAM wParam, LPARAM lParam) { 
      if (MustProcessMessage != HC_ACTION) { return NativeCalls.Hooks.CallNextHookEx(KeyboardHookProcedureHandle, MustProcessMessage, wParam, lParam); } 

      var KeyInfo = (KBDLLHOOKSTRUCT)Marshal.PtrToStructure(lParam, typeof(KBDLLHOOKSTRUCT)); 
      return HandlerI(wParam, lParam, KeyInfo) ? (IntPtr)1 : NativeCalls.Hooks.CallNextHookEx(KeyboardHookProcedureHandle, MustProcessMessage, wParam, lParam);

GetAsyncKeyState就在你打電話的那一刻，不跟你計較其他鍵同步的狀態檢索狀態代碼摘錄。你已經有了一個鉤子，你可以在鉤子中跟蹤自己的Win鍵狀態。
