Question

In my load event on a form, I call some method in a try catch block. When an Exception occurs, I show the user a message and after that I want to close the form. It looks like this (code in Load event):

try
{
   Metehod();
}
catch(DatabaseException ex)
{
  MessageBox.show("db error! " + ex.Message);
  this.Close();
}
catch(Exception ex)
{
  MessageBox.Show("Unknown error!" + ex.Message);
  this.Close();
}

But, when this.CLose() is called, it doesn’t close the form, no, the code keeps running till the end of the load event!

Why is this? Is this logical behaviour?

Answer 1

Yes, it is logical behaviour. Calling Close() does not return control to the caller. The method will continue execution unless you tell it otherwise. Putting a return after each this.Close() does the trick.
