is there a way to detect all the key pressed in keydown event of the form? For example im currently pressing CRTL + Alt + A can i get all the keys in keydown event? i need to get all the keys to create my own hot keys in my currently developing application

推荐答案

如果要查找按下了哪些键，可以这样做

If you want to find which keys are pressed, you could do this,

     if ((Keyboard.Modifiers & ModifierKeys.Alt) == ModifierKeys.Alt) // Is Alt key pressed
        {
            if (Keyboard.IsKeyDown(Key.LeftCtrl) && Keyboard.IsKeyDown(Key.A))
            {
                MessageBox.Show("Key pressed"); 
            }
       }
