Handle the KeyDown Event when ALT+KEY is Pressed

Question

How do you handle a KeyDown event when the ALT key is pressed simultaneously with another key in .NET?

Answer 1

The KeyEventArgs class defines several properties for key modifiers - Alt is one of them and will evaluate to true if the alt key is pressed.

Answer 2

private void Form1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.Alt && e.KeyData != (Keys.RButton | Keys.ShiftKey | Keys.Alt))
    {
        // ...
    }
}

Answer 3

Something like:

   private void Form1_KeyDown(object sender, KeyEventArgs e)
   {
        if (e.Alt)
        {
            e.Handled = true;
            // ,,,
        }
    }
