[This topic is pre-release documentation and is subject to change in future releases. Blank topics are included as placeholders.]

Enumerates the indices of all the items in a list equal to one of several given items. The passed BinaryPredicate is used to determine if two items are "equal".

Namespace: Wintellect.PowerCollections
Assembly:  PowerCollections (in PowerCollections.dll)

Syntax

C#
public static IEnumerable<int> IndicesOfMany<T>(
	IList<T> list,
	IEnumerable<T> itemsToLookFor,
	BinaryPredicate<T> predicate
)
Visual Basic (Declaration)
Public Shared Function IndicesOfMany(Of T) ( _
	list As IList(Of T), _
	itemsToLookFor As IEnumerable(Of T), _
	predicate As BinaryPredicate(Of T) _
) As IEnumerable(Of Integer)
Visual C++
public:
generic<typename T>
static IEnumerable<int>^ IndicesOfMany (
	IList<T>^ list, 
	IEnumerable<T>^ itemsToLookFor, 
	BinaryPredicate<T>^ predicate
)

Parameters

list
IList<(Of <T>)>
The list to search.
itemsToLookFor
IEnumerable<(Of <T>)>
A collection of items to search for.
predicate
BinaryPredicate<(Of <T>)>
The BinaryPredicate used to compare items for "equality".

Return Value

An IEnumerable<T> that enumerates the indices of items "equal" to any of the items in the collection itemsToLookFor, using as the test for equality.

Type Parameters

T

Remarks

Since an arbitrary BinaryPredicate is passed to this function, what is being removed need not be true equality. This methods finds last item X which satisfies BinaryPredicate(X,Y), where Y is one of the items in itemsToLookFor
