ScanRightExtensionScanRightTSource, TAccumulate Method (IEnumerableTSource, TAccumulate, FuncTSource, TAccumulate, TAccumulate)

Peforms a right-associative scan (inclusive prefix) on a sequence of elements. The specified seed value is used as the initial accumulator value. This operator is the right-associative version of the ScanTSource, TState(IEnumerableTSource, TState, FuncTState, TSource, TState) LINQ operator.

Namespace:  MoreLinq.Extensions
Assembly:  MoreLinq (in MoreLinq.dll) Version: 3.3.1+b77df70598ab84c28cd43dcf74594024b6d575e1
Syntax
Copy
public static IEnumerable<TAccumulate> ScanRight<TSource, TAccumulate>(
	this IEnumerable<TSource> source,
	TAccumulate seed,
	Func<TSource, TAccumulate, TAccumulate> func
)

Parameters

source
Type: System.Collections.GenericIEnumerableTSource
Source sequence.
seed
Type: TAccumulate
The initial accumulator value.
func
Type: SystemFuncTSource, TAccumulate, TAccumulate
A right-associative accumulator function to be invoked on each element.

Type Parameters

TSource
The type of the elements of source.
TAccumulate
The type of the accumulator value.

Return Value

Type: IEnumerableTAccumulate
The scanned sequence.

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. Source sequence is consumed greedily when an iteration of the resulting sequence begins.
Examples
Copy
var result = Enumerable.Range(1, 4).ScanRight("5", (a, b) => string.Format("({0}/{1})", a, b));
The result variable will contain [ "(1+(2+(3+(4+5))))", "(2+(3+(4+5)))", "(3+(4+5))", "(4+5)", "5" ].
