Linq Select Subset of master list

Question

I have a master list of complex objects.

I have a list of int ids that I need to select the corresponding complex object out of the master list.

this doesn't work

MasterListofComplexObj.Where(u => MasterListofComplexObj.Select(i => i.Id).Contains(ChildListofIntIds));

any help would be appreciated.

Answer 1

This should work:

var results = MasterListofComplexObj.Where(u => ChildListofIntIds.Contains(u.Id));
