Multiple C # Key Presses

I program the game in Microsoft Visual Studio C # and I have to catch many keys at the same time. I cannot detect Q, W, E, R, T, Y at the same time, but I can determine Q, W, E, R, T, A.

I tried using KeyDown and [DllImport("user32.dll")] , but both of them have the same result. What is the difference between Y and A keys and how can I solve this problem?

 int code1 = GetVirtualKeyCode(Keys.Q); int code2 = GetVirtualKeyCode(Keys.W); int code3 = GetVirtualKeyCode(Keys.E); int code4 = GetVirtualKeyCode(Keys.R); int code5 = GetVirtualKeyCode(Keys.T); int code6 = GetVirtualKeyCode(Keys.Y); if ((array[code1] & 0x80) != 0 && (array[code2] & 0x80) != 0 && (array[code3] & 0x80) != 0 && (array[code4] & 0x80) != 0 && (array[code5] & 0x80) != 0 && (array[code6] & 0x80) != 0) { listBox1.Items.Add("asdasdasd"); }

This may be related to your keyboard. When I was a gamer, I know that it is a property of keys to send multiple keystrokes at the same time; Depending on the keyboard, the number will be different, but different combinations will or will not work.

This is called key scrolling. USB keyboards only support scrolling of the final key, while some smart PS / 2 keyboards have n-key rollovers (many many keys can be pressed simultaneously without disabling additional keystrokes)
