Syntax

public static IOrderedEnumerable<TElement> OrderBy<TElement, TKey>(
	this IEnumerable<TElement> source,
	Func<TElement, TKey> keySelector,
	bool ascending
)

<ExtensionAttribute>
Public Shared Function OrderBy(Of TElement, TKey) ( 
	source As IEnumerable(Of TElement),
	keySelector As Func(Of TElement, TKey),
	ascending As Boolean
) As IOrderedEnumerable(Of TElement)

public:
[ExtensionAttribute]
generic<typename TElement, typename TKey>
static IOrderedEnumerable<TElement>^ OrderBy(
	IEnumerable<TElement>^ source, 
	Func<TElement, TKey>^ keySelector, 
	bool ascending
)

[<ExtensionAttribute>]
static member OrderBy : 
        source : IEnumerable<'TElement> * 
        keySelector : Func<'TElement, 'TKey> * 
        ascending : bool -> IOrderedEnumerable<'TElement>

Parameters

source: Type: System.Collections.GenericIEnumerableTElement
A sequence of values to order.
keySelector: Type: SystemFuncTElement, TKey
A function to extract a key from an element.
ascending: Type: SystemBoolean
to sort in ascending order; to sort in descending order.

Type Parameters

TElement: The type of the element of source.
TKey: The type of the key returned by keySelector.

Return Value

Type: IOrderedEnumerableTElement
An IOrderedEnumerableTElement whose elements are sorted according to a key.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerableTElement. When you use instance method syntax to call this method, omit the first parameter.
