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); } 

Answer 2

You should just be able to set the Form's CancelButton property to your Cancel button and then you won't need any code.
