The [`DistinctBy`](xref:System.Linq.Enumerable.DistinctBy%2A?displayProperty=nameWithType) is an alternative approach to `Distinct` that takes a `keySelector`. The `keySelector` is used as the comparative discriminator of the source type. In the following code, words are discriminated based on their `Length`, and the first word of each length is displayed:

The <xref:System.Linq.Enumerable.ExceptBy%2A> method is an alternative approach to `Except` that takes two sequences of possibly heterogenous types and a `keySelector`. The `keySelector` is the same type as the first collection's type. Consider the following `Teacher` array and teacher IDs to exclude. To find teachers in the first collection that aren't in the second collection, you can project the teacher's ID onto the second collection:
