C # Simple Method for responding to the carriage return event in winform. Press enter to execute the OK button event.

The buttons in winform need to respond to the carriage return event, which is very simple! You only need to set the attribute in the form!
For example, there is a login form (form_login), including two buttons (btnlogin) and two buttons (btnexit ),
You want to log on (btnlogin) to respond to the Enter key,
Set the form (form_login) attribute acceptbutton to btnlogin!
That is, form_login.acceptbutton = btnlogin; similarly,
Set the cancelbutton attribute of the form (form_login) to btnexit to respond to the ESC key!
That is, form_login.cancelbutton = btnexit;
