How to get IsKeyDown method to work in C#

Question

I can’t figure out how get this method to work:

System.Windows.Input.Keyboard.IsKeyDown(System.Windows.Input.Key)

The object browser says

Answer 1

IsKeyDown is static, so you need to use it like

Keyboard.IsKeyDown()

Not with an instantiated object.

You also need to make sure you have the correct using statement at the top:

using System.Windows.Input;

EDIT

On further inspection, Keyboard is a static class... So you can't Keyboard test = new Keyboard();

Answer 2

Add PresentationCore.dll assembly as a reference.

Add WindowsBase.dll assembly as a reference.

Test code:

private void buttonMisc_Click(object sender, EventArgs e)
{
    if (System.Windows.Input.Keyboard.IsKeyDown(System.Windows.Input.Key.LeftShift) == true)
        MessageBox.Show("Got it!");
}
