DisposableAction and Marshal.ReleaseComObject

问题

doing some office Interop and the code is of Type

            try
            {
                selection = getSelected(Return.Some.Office.InteropObject);
                for ( int i = 0 ; i < selection.count ; i++)
                    yield return selection.item(i)
            }
            finally
            {
                Marshal.ReleaseComObject(selection);
            }

Wondering if it's a good idea to replace it with a DisposableAction and change to

         using ( var a = new DisposableAction(getSelected(Return.Some.Office.InteropObject)) )
         {
              foreach(var b in a.Items)
                yield return b;
         }
