如何在.NET中找到NumLock，CapsLock和ScrollLock的状态？

导入WinAPI函数GetKeyState

[Dllimport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true, CallingConvention = CallingConvention.Winapi)]public static extern short GetKeyState(int keyCode);

然后你可以像那样使用它

bool CapsLock = (((ushort)GetKeyState(0x14)) & 0xffff) != 0;bool NumLock = (((ushort)GetKeyState(0x90)) & 0xffff) != 0;bool ScrollLock = (((ushort)GetKeyState(0x91)) & 0xffff) != 0;

编辑：以上内容适用于框架1.1，适用于框架2.0 +

Control.IsKeyLocked
