AlgorithmsFirstIndexOfManyT Method (IListT, IEnumerableT, BinaryPredicateT)
Finds the index of the first item in a list "equal" to one of several given items. The passed BinaryPredicate is used to determine if two items are "equal".

Namespace: X3Platform.Collections
Assembly: X3Platform.Support (in X3Platform.Support.dll) Version: 1.0.0.0 (2.0.0.0)
Syntax
Copy
public static int FirstIndexOfMany<T>(
	IList<T> list,
	IEnumerable<T> itemsToLookFor,
	BinaryPredicate<T> predicate
)

Parameters

list
Type: System.Collections.GenericIListT
The list to search.
itemsToLookFor
Type: System.Collections.GenericIEnumerableT
The items to search for.
predicate
Type: X3Platform.CollectionsBinaryPredicateT
The BinaryPredicate used to compare items for "equality".

Type Parameters

T

[Missing <typeparam name="T"/> documentation for "M:X3Platform.Collections.Algorithms.FirstIndexOfMany``1(System.Collections.Generic.IList{``0},System.Collections.Generic.IEnumerable{``0},X3Platform.Collections.BinaryPredicate{``0})"]

Return Value

Type: Int32
The index of the first item "equal" to any of the items in the collection itemsToLookFor, using as the test for equality. -1 if no such item exists in the list.
Remarks
Since an arbitrary BinaryPredicate is passed to this function, what is being removed need not be true equality. This methods finds first item X which satisfies BinaryPredicate(X,Y), where Y is one of the items in itemsToLookFor
