Syntax
public static class ProjectionComparerMethods
Create<TSource, TKey>(TSource, Func<TSource, TKey>)
Creates an instance of ProjectionComparer using the specified projection. The ignored parameter is solely present to aid type inference.
Declaration

|---|---|
| ProjectionComparer<TSource, TKey> | A comparer which will compare elements by projecting each element to its key, and comparing keys |
Type Parameters
| Name | Description |
|---|---|
| TSource | Type parameter for the elements to be compared |
