generic<typename TSource>
static IQueryable<TSource>^ AggregateAsQuery(
	IQueryable<TSource>^ source, 
	Expression<Func<TSource, TSource, TSource>^>^ func
)

Parameters

source: Type: System.LinqIQueryableTSource
The input sequence
func: Type: System.Linq.ExpressionsExpressionFuncTSource, TSource, TSource
An accumualator function to apply to each element

Type Parameters

TSource: The type of the elements of source

Return Value

Type: IQueryableTSource
The final accumulator value
