winforms - Escape button to close Windows Forms form in C#

Question

I have tried the following:

private void Form1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
    if ((Keys) e.KeyValue == Keys.Escape)
        this.Close();
}

But it doesn't work.

Then I tried this:

protected override void OnKeyDown(KeyEventArgs e)
{
    base.OnKeyDown(e);
    if (e.KeyCode == Keys.Escape)
        this.Close();
}

And still nothing's working.

The KeyPreview on my Windows Forms form properties is set to true... What am I doing wrong?

Answer 1

This will always work, regardless of proper event handler assignment, KeyPreview, CancelButton, etc:

protected override bool ProcessCmdKey(ref Message msg, Keys keyData) {
    if (keyData == Keys.Escape) {
        this.Close();
        return true;
    }
    return base.ProcessCmdKey(ref msg, keyData);
}
