How to check if a key was pressed in C#? (.NET 6)

Question

I would like to check if the alt key was pressed in c#. I could only find old information that didn't work. It would be helpful if you send an example with the alt key. Thanks in advance!

If you need to detect a modifier key outside of a KeyEventHandler method, you can use the static Keyboard class from System.Windows.Input.

Example from my WPF .NET 6.0 Application on Windows

if (Keyboard.Modifiers.HasFlag(ModifierKeys.Alt))
{
    // Do something
}
