Using Exit button to close a winform program

The FormClosed Event is an Event that fires when the form closes. It is not used to actually close the form. You'll need to remove anything you've added there.

All you should have to do is add the following line to your button's event handler:

this.Close();

this.Close();

Closes the form programmatically.

Remove the method, I suspect you might also need to remove it from your Form.Designer.

Otherwise: Application.Exit();

Should work.

That's why the designer is bad for you. :)

We can close every window using Application.Exit(); Using this method we can close hidden windows also.

private void btnExitProgram_Click(object sender, EventArgs e) { Application.Exit(); }
