Question

I wonder, if someone could help me…

Is there a LINQ query that will return a bool, if any item from one IList<> is contained int another IList<>.

These IList<>'s are object and I need to compare one a single property of the object, the “Name” property in this case?

Is there a LINQ query that can do this? If so could someone show me the correct implementation?

Thank you

Well you could project both lists:

if (list1.Select(x => x.Name)
         .Intersect(list2.Select(x => x.Name))
         .Any())

Is that what you’re after?
