Why use Finally in Try … Catch

Question

I see that the Finally in Try .. Catch will always execute after any parts of the execution of the try catch block.

Is it any different to

Answer 1

Yes, it is different. Finally will always run (barring program crash). If the function exits inside of the try catch block, or another error is thrown in either the try or the catch, the finally will still execute. You won't get that functionality not using the finally statement.

Answer 2

What I often use is (I encapsulated that into an aspect, but this is what I derived the aspect of):

public static DoLengthyProcessing(this Control control, Action<Control> action)
{
    Cursor oldCursor = control.Cursor
    try
    {
        control.Cursor = Cursors.WaitCursor;
        action(control);
    }
    catch (Exception ex)
    {
        ErrorHandler.Current.Handler(ex);
    }
    finally
    {
        control.Cursor = oldCursor;
    }
}

Or, use AOP (as I do).
