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

using System;
using System.Windows.Forms;

class Program
{
    static void Main()
    {
        bool numLock = Control.IsKeyLocked(Keys.NumLock);
        bool capsLock = Control.IsKeyLocked(Keys.CapsLock);
        bool scrollLock = Control.IsKeyLocked(Keys.Scroll);

        Console.WriteLine("NumLock: " + numLock);
        Console.WriteLine("CapsLock: " + capsLock);
        Console.WriteLine("ScrollLock: " + scrollLock);
    }
}
