Parameters

source IEnumerableT: An enumeration over which to find the middle element(s).

Type Parameters

T: Type of elements in the source

Return Value

IEnumerableT
The middle item(s) from an enumeration, or null if source is null.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerableT. 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).

Remarks

If enumeration length is even, two items will be returned representing the items in the middle of the set; otherwise, if the enumeration length is odd, one item will be returned from exactly the middle of the set.
