- source IEnumerableTSource
- Source sequence
- selector FuncTSource, TKey
- Selector to use to pick the results to compare
- comparer IComparerTKey
- Comparer to use to compare projected values
- TSource
- Type of the source sequence

- Type of the projected element
IExtremaEnumerableTSourceThe sequence of maximal elements, according to the projection.In Visual Basic and C#, you can call this method as an instance method on any object of type
IEnumerableTSource. When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
Extension Methods (C# Programming Guide).
This operator uses deferred execution. The results are evaluated
and cached on first use to returned sequence.
