Here Exception as being the base, will absorb all exception, so if you place Exception e as first catch, no other catch block will execute. So I placed Exception ex as the last catch as catches are matched sequentially. www.abhisheksur.com Nav234, if this helps please login to Mark As Answer. \| Alert Moderator

Are you looking for something like this :

 try

                {



                    return (Earth)planets[index];

                }

                catch (InvalidCastException ex)

                {

                    Debug.Write(ex.Message);

                }

                catch (IndexOutOfRangeException ex)

                {

                    Trace.TraceError(ex.Message);

                }

                catch (Exception ex)

                {

                    throw ex;

                }
