AggregateRightExtension.AggregateRight<TSource, TAccumulate>(IEnumerable<TSource>, TAccumulate, Func<TSource, TAccumulate, TAccumulate>) Method

Applies a right-associative accumulator function over a sequence. The specified seed value is used as the initial accumulator value. This operator is the right-associative version of the Aggregate<TSource, TAccumulate>(IEnumerable<TSource>, TAccumulate, Func<TAccumulate, TSource, TAccumulate>) LINQ operator.

public:
[ExtensionAttribute]
generic<typename TSource, typename TAccumulate>
static TAccumulate AggregateRight(
	IEnumerable<TSource>^ source, 
	TAccumulate seed, 
	Func<TSource, TAccumulate, TAccumulate>^ func

F#
[<ExtensionAttribute>]
static member AggregateRight : 
        source : IEnumerable<'TSource> * 
        seed : 'TAccumulate * 
        func : Func<'TSource, 'TAccumulate, 'TAccumulate> -> 'TAccumulate 

Parameters

source IEnumerable<TSource>: Source sequence.
seed TAccumulate: The initial accumulator value.
func Func<TSource, 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

TAccumulate
The final accumulator value.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable<TSource>. 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 executes immediately.

Example

C#
var numbers = Enumerable.Range(1, 5);
string result = numbers.AggregateRight("6", (a, b) => $"({a}/{b})");

The result variable will contain "(1/(2/(3/(4/(5/6)))))".
