Syntax

C++

Copy

public static IEnumerable<T> FillForward<T>(
	this IEnumerable<T> source
)

<ExtensionAttribute>
Public Shared Function FillForward(Of T) ( 
	source As IEnumerable(Of T)
) As IEnumerable(Of T)

public:
[ExtensionAttribute]
generic<typename T>
static IEnumerable<T>^ FillForward(
	IEnumerable<T>^ source
)

[<ExtensionAttribute>]
static member FillForward : 
        source : IEnumerable<'T> -> IEnumerable<'T>

Parameters

source: Type: System.Collections.GenericIEnumerableT
The source sequence.

Type Parameters

T: Type of the elements in the source sequence.

Return Value

Type: IEnumerableT
An IEnumerableT with null references or values replaced.

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

This method uses deferred execution semantics and streams its results. If references or values are null at the start of the sequence then they remain null.
