Sort one list by another

Question

I have 2 list objects, one is just a list of ints, the other is a list of objects but the objects has an ID property.

What i want to do is sort the list of objects b

Answer 1

One possible solution:

myList = myList.OrderBy(x => Ids.IndexOf(x.Id)).ToList();

Note: use this if you working with In-Memory lists, doesn't work for IQueryable type, as IQueryable does not contain a definition for IndexOf
