Linq Distinct based on property of object

Question

Is it possible to get the distinct elements of a List based on a property of the objects in the List?

Someting like: Distinct(x => x.id)

What's not usefull for me is following: .Select(x => x.id).Distinct() because then I would get back a List<int> instead of List<MyClass>

Answer 1

That sounds like a grouping construct to me, because you need to decide which of the supposedly identical object you actually want to return

var q = from x in foo
        group x by x.Id into g
        select g.First(); // or some other selection from g

Just because Id is identical across multiple items doesn't mean that the items are identical on other properties, so you need to explicitly decide which item is returned.
