Namespace: MoreLinq.Extensions
Assembly: MoreLinq (in MoreLinq.dll) Version: 3.0.0

Syntax

public static IEnumerable<T> Pipe<T>(
	this IEnumerable<T> source,
	Action<T> action
)

<ExtensionAttribute>
Public Shared Function Pipe(Of T) ( 
	source As IEnumerable(Of T),
	action As Action(Of T)
) As IEnumerable(Of T)

public:
[ExtensionAttribute]
generic<typename T>
static IEnumerable<T>^ Pipe(
	IEnumerable<T>^ source, 
	Action<T>^ action
)

[<ExtensionAttribute>]
static member Pipe : 
        source : IEnumerable<'T> * 
        action : Action<'T> -> IEnumerable<'T>

Parameters

source: Type: System.Collections.GenericIEnumerableT
The sequence of elements
action: Type: SystemActionT
The action to execute on each element

Type Parameters

T: The type of the elements in the sequence

Return Value

Type: IEnumerableT
A sequence with source elements in their original order.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerableT. 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 returned sequence is essentially a duplicate of the original, but with the extra action being executed while the sequence is evaluated. The action is always taken before the element is yielded, so any changes made by the action will be visible in the returned sequence. This operator uses deferred execution and streams it results.
