MoreEnumerableAggregateRightTSource, TAccumulate, TResult Method (IEnumerableTSource, TAccumulate, FuncTSource, TAccumulate, TAccumulate, FuncTAccumulate, TResult) |
Applies a right-associative accumulator function over a sequence.
The specified seed value is used as the initial accumulator value,
and the specified function is used to select the result value.
This operator is the right-associative version of the
AggregateTSource, TAccumulate, TResult(IEnumerableTSource, TAccumulate, FuncTAccumulate, TSource, TAccumulate, FuncTAccumulate, TResult) LINQ operator.

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. - resultSelector
- Type: SystemFuncTAccumulate, TResult
A function to transform the final accumulator value into the result value.
Type Parameters
- TSource
- The type of the elements of source.
- TAccumulate
- The type of the accumulator value.
- TResult
- The type of the resulting value.
Return Value
Type:
TResultThe transformed final accumulator value.
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 executes immediately.
Examples var numbers = Enumerable.Range(1, 5);
int result = numbers.AggregateRight("6", (a, b) => string.Format("({0}/{1})", a, b), str => str.Length);
The
result variable will contain
21.
