This is windows, so there are at least two ways, Control.IsKeyLocked[^] and Console.CapsLock[^]

C#

if (Control.IsKeyLocked(Keys.CapsLock))
    {
    Console.WriteLine("The Caps Lock key is ON.");
    }
else
    {
    Console.WriteLine("The Caps Lock key is OFF.");
    }

And

C#

if (Console.CapsLock)
    {
    Console.WriteLine("The Caps Lock key is ON.");
    }
else
    {
    Console.WriteLine("The Caps Lock key is OFF.");
    }

For Windows Forms, have a look at the Control.IsKeyLocked method[^].
