MoreEnumerableBatchTSource Method (IEnumerableTSource, Int32)

Batches the source sequence into sized buckets.

Namespace:  MoreLinq
Assembly:  MoreLinq (in MoreLinq.dll) Version: 3.3.1+b77df70598ab84c28cd43dcf74594024b6d575e1
Syntax
public static IEnumerable<IEnumerable<TSource>> Batch<TSource>(
	this IEnumerable<TSource> source,
	int size
)

Parameters

source
Type: System.Collections.GenericIEnumerableTSource
The source sequence.
size
Type: SystemInt32
Size of buckets.

Type Parameters

TSource
Type of elements in source sequence.

Return Value

Type: IEnumerableIEnumerableTSource
A sequence of equally sized buckets containing elements of the source collection.

Usage Note

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

This operator uses deferred execution and streams its results (buckets are streamed but their content buffered).

When more than one bucket is streamed, all buckets except the last is guaranteed to have size elements. The last bucket may be smaller depending on the remaining elements in the source sequence.

Each bucket is pre-allocated to size elements. If size is set to a very large value, e.g. MaxValue to effectively disable batching by just hoping for a single bucket, then it can lead to memory exhaustion (OutOfMemoryException).
