This only works in situations where you have a numeric field  but you can put a minus sign in front of the field name like so   reportingNameGroups   reportingNameGroups OrderBy x  gt  - x GroupNodeId     However this works a little bit different than OrderByDescending when you have are running it on an int  or double  or decimal  fields   What will happen is on OrderByDescending the nulls will be at the end  vs with this method the nulls will be at the beginning  Which is useful if you want to shuffle nulls around without splitting data into pieces and splicing it later
