C++/CLI

Vector<TResult>^ AggregateBy(
	IVector^ values1, 
	IVector^ values2, 
	IGrouping^ grouping, 
	Vector<TResult>^ result
)

abstract AggregateBy : 
        values1 : IVector * 
        values2 : IVector * 
        grouping : IGrouping * 
        result : Vector<'TResult> -> Vector<'TResult>

Parameters

values1 IVector: A vector of values.
values2 IVector: A vector of values.
grouping IGrouping: The object that specifies the grouping.
result Vector<TResult>: The vector that is to hold the result.

Return Value

Vector<TResult>
The result of aggregating the corresponding elements of values1 and values2 according to the groups defined by grouping.
