static IOrderedEnumerable<T>^ ThenBy(
	IOrderedEnumerable<T>^ source, 
	Func<T, TKey>^ keySelector, 
	OrderByDirection direction
)

F#

[<ExtensionAttribute>]
static member ThenBy : 
        source : IOrderedEnumerable<'T> * 
        keySelector : Func<'T, 'TKey> * 
        direction : OrderByDirection -> IOrderedEnumerable<'T>

Parameters

source IOrderedEnumerableT: The sequence to order
keySelector FuncT, TKey: A key selector function
direction OrderByDirection: A direction in which to order the elements (ascending, descending)

Type Parameters

T: The type of the elements in the source sequence
TKey: The type of the key used to order elements

Return Value

IOrderedEnumerableT
An ordered copy of the source sequence

Usage Note

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