Keyboard.Modifiers Property

Gets the set of ModifierKeys that are currently pressed.

Namespace:  System.Windows.Input
Assembly:  PresentationCore (in PresentationCore.dll)

public static ModifierKeys Modifiers { get; }

Property Value

Type: System.Windows.Input.ModifierKeys
A bitwise combination of the ModifierKeys values.

ModifierKeys is a bit field enumeration, so it is possible for multiple modifier keys to be pressed at the same time. Use bit operations to determine the exact set of modifier keys pressed.

The following example uses a bit AND comparison to determine if the Control modifier key is pressed.

if ((Keyboard.Modifiers & ModifierKeys.Control) > 0)
{
    button1.Background = Brushes.Red;
}
else
{
    button1.Background = Brushes.Blue;
}
