Processes a sequence into a series of subsequences representing a windowed subset of the original

Namespace: MoreLinq.Extensions
Assembly: MoreLinq (in MoreLinq.dll) Version: 3.3.1+b77df70598ab84c28cd43dcf74594024b6d575e1

Syntax

C++

Copy

public static IEnumerable<IList<TSource>> Window<TSource>(
	this IEnumerable<TSource> source,
	int size
)

<ExtensionAttribute>
Public Shared Function Window(Of TSource) ( 
	source As IEnumerable(Of TSource),
	size As Integer
) As IEnumerable(Of IList(Of TSource))

public:
[ExtensionAttribute]
generic<typename TSource>
static IEnumerable<IList<TSource>^>^ Window(
	IEnumerable<TSource>^ source, 
	int size
)

[<ExtensionAttribute>]
static member Window : 
        source : IEnumerable<'TSource> * 
        size : int -> IEnumerable<IList<'TSource>>

Parameters

source: Type: System.Collections.Generic.IEnumerable<TSource>
The sequence to evaluate a sliding window over
size: Type: System.Int32
The size (number of elements) in each window

Type Parameters

TSource: The type of the elements of the source sequence

Return Value

Type: IEnumerable<IList<TSource>>
A series of sequences representing each sliding window subsequence

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).

Remarks

The number of sequences returned is: Max(0, sequence.Count() - windowSize) + 1
Returned subsequences are buffered, but the overall operation is streamed.
