Detect shift key on application startup in C#/Windows Forms

Question

Is there a way to get a standard Windows Forms application to detect if the Shift key is being held down on application startup - without using Windows hooks?

I ideally would like the workflow to change from normal if the shift key is held down when the EXE file is run.

Answer 1

The ModifierKeys property looks ideal:

private void Form1_Load(object sender, EventArgs e)
{
    if ( (ModifierKeys & Keys.Shift) != 0)
    {
      MessageBox.Show("Shift is pressed");
    }
}
