The source sequence. - count
- Type: System.Int32
Number of (maximum) elements to return. - keySelector
- Type: System.Func<TSource, TKey>
A function to extract a key from an element.
Type Parameters

Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type
IEnumerable<TSource>. 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).
