Methods

EnumerableReduce<T, TRes>(IEnumerable<T>, TRes, Func<TRes, T, TRes>, Func<TRes, T, Int32, TRes>)

Reduces across an enumerable, supporting sparse enumerables

Declaration

public static TRes EnumerableReduce<T, TRes>(this IEnumerable<T> source, TRes initial, Func<TRes, T, TRes> fun, Func<TRes, T, int, TRes> repeatedFun)

Parameters

Type	Name	Description
IEnumerable<T>	source	This collection
TRes	initial	Initial value for reduction
Func<TRes, T, TRes>	fun	The function
Func<TRes, T, Int32, TRes>	repeatedFun	The function when the same value enters the reduction several times.

Returns

Type	Description
TRes

Type Parameters

Name	Description
T	Type of this collection
TRes	Type of result
