EnumerableExMemoizeTSource Method (IEnumerableTSource, Int32)
Creates a buffer with a view over the source sequence, causing a specified number of enumerators to obtain access to all of the sequence's elements without causing multiple enumerations over the source.

Namespace: System.Linq
Assembly: System.Interactive (in System.Interactive.dll) Version: 1.2.0.0
Syntax
C#
Copy
public static IBuffer<TSource> Memoize<TSource>(
	this IEnumerable<TSource> source,
	int readerCount
)

Parameters

source
Type: System.Collections.GenericIEnumerableTSource
Source sequence.
readerCount
Type: SystemInt32
Number of enumerators that can access the underlying buffer. Once every enumerator has obtained an element from the buffer, the element is removed from the buffer.

Type Parameters

Source sequence element type.

Return Value

Type: IBufferTSource
Buffer enabling a specified number of enumerators to retrieve all elements from the shared source sequence, without duplicating source enumeration side-effects.
