Avoid to access the array directly and better use GetDimensionRegionByValue() instead, but of course in some cases it makes sense to use the array (e.g. iterating through all DimensionRegions). Use AddDimension() and DeleteDimension() to create a new dimension or delete an existing one (which will create or delete the respective dimension region(s) automatically).
