SelectMany(TSource, TCollection, TResult) Method (IEnumerable(TSource), Func(TSource, BcfReadOnlyArrayList(TCollection)), Func(TSource, TCollection, TResult))

BcfReadOnlyArrayListExtensionsSelectManyTSource, TResult Method (IEnumerableTSource, FuncTSource, BcfReadOnlyArrayListTResult)

[This is preliminary documentation and is subject to change.]

Projects each element of a sequence to an IEnumerableT, flattens the resulting sequences into one sequence.

Namespace: System.Linq
Assembly: CalculationWorks.BusinessModel (in CalculationWorks.BusinessModel.dll) Version: 4.0.0-beta7

Syntax

Copy

public static IEnumerable<TResult> SelectMany<TSource, TResult>(
	this IEnumerable<TSource> source,
	Func<TSource, BcfReadOnlyArrayList<TResult>> collectionSelector
)

<ExtensionAttribute>
Public Shared Function SelectMany(Of TSource, TResult) ( 
	source As IEnumerable(Of TSource),
	collectionSelector As Func(Of TSource, BcfReadOnlyArrayList(Of TResult))
) As IEnumerable(Of TResult)

Parameters

source: Type: System.Collections.GenericIEnumerableTSource
The source.
collectionSelector: Type: SystemFuncTSource, BcfReadOnlyArrayListTResult
A transform function to apply to each element of the input sequence.

Type Parameters

TSource: The type of the elements of source.
TResult: The type of the elements of the resulting sequence.

Return Value

Type: IEnumerableTResult
An IEnumerableT whose elements are the result of invoking the one-to-many transform function collectionSelector on each element of source and then mapping each of those sequence elements and their corresponding source element to a result element.

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.
