Chunkify<T> Method

Convert a sequence into a sequence of arrays (chunks) with specified length.

Syntax

Visual Basic
C#

'Declaration
 
<ExtensionAttribute()>
Public Shared Function Chunkify(Of T)( _
   ByVal source As IEnumerable(Of T), _
   ByVal chunkSize As Integer _
) As IEnumerable(Of IList(Of T))

'Usage
 
Dim source As IEnumerable(Of T)
Dim chunkSize As Integer
Dim value As IEnumerable(Of IList(Of T))
 
value = EnumerableExtensions.Chunkify(Of T)(source, chunkSize)

[Extension()]
public static IEnumerable<IList<T>> Chunkify<T>( 
   IEnumerable<T> source,
   int chunkSize
)

Parameters

source: A sequence of values
chunkSize: The maximum number of elements in each chunk

Type Parameters

T: The type of the elements of source

Return Value

An IEnumerable{T} whose elements are arrays

Remarks

For example, with chunk size = 3, this method converts the following sequence into a sequence with two arrays: [ 1, 2, 3, 4, 5 ] => [ [ 1, 2, 3 ], [ 4, 5 ] ]

Keep in mind, this simple implementation is not optimal for all situations. It is suitable for small sequences, yet may not be memory efficient for large sequences, and definitely not acceptable for infinite sequences.

See %% for a discussion of different approaches to chunking.

Example

For example, with chunk size = 3, this method converts the following sequence into a sequence with two arrays: [ 1, 2, 3, 4, 5 ] => [ [ 1, 2, 3 ], [ 4, 5 ] ]
