Advantage of using DialogResult.Cancel

What would the advantage of using:

DialogResult.Cancel

Over using: 

this.Close()

Would it be just so that you would be able to determine that the user has selected Cancel?

You can use it value for this kind of purpose 

var result = form.ShowDialog();
if (result == DialogResult.OK) 
{

}
else if (result == DialogResult.Cancel) 
{
  //perform soem operation
}

So if you want to perform some operation on the result of dialog you can use this.

Note :

Both of this ok and cancel operation on dialog close your dialog, and by catching ok and cancel value you can perform extra task as given in above example.

Those consuming your interface, if showing the form with ShowDialog, would get a result. They would know the user pressed Cancel.

As an aside. You can set the Form properties AcceptButton and CancelButton. Then, if the form is shown with ShowDialog, when they are clicked the base Form will set the DialogResult and thus the Form will close on its own.
