I wonder if there is a way of writing a method or a class that would add to any method some code that is shared between many methods. The methods return different things and some of them are just void.

Below is a part of the code that is duplicated in the methods.

            StartTimer(MethodBase.GetCurrentMethod().Name);
            try
            {
                // Actual method body
            }
            catch (Exception ex)
            {
                bool rethrow = ExceptionPolicy.HandleException(ex, "DALPolicy");
                if (rethrow)
                {
                    throw;
                }
            }
            finally
            {
                StopTimer(MethodBase.GetCurrentMethod().Name);
            }

Any help would be greatly appreciated.
