Disjoint Union in LINQ

问题

I have two sets (ILists) where I need all the items from the 1st list, where the item is not in the second list.

Can anyone point me to the best way of achieving this with a LINQ statement?

回答1:

How about the Except method:

var firstMinusSecond = first.Except(second);
