BinarySearch(TListItem, TMatchItem) Method (IList(TListItem), TMatchItem, CollectionAlgorithms.ComparisonOfDifferentTypes(TListItem, TMatchItem), Int32, Int32)

CollectionAlgorithmsBinarySearchT Method (IListT, T)

Uses a binary search algorithm to locate a specific element in the sorted IListT.

Namespace: AGI.Foundation.Infrastructure
Assembly: AGI.Foundation.Core (in AGI.Foundation.Core.dll) Version: 25.2.423.0 (25.2.423.0)

Syntax

C++

Copy

public static int BinarySearch<T>(
	IList<T> collection,
	T item
)

Public Shared Function BinarySearch(Of T) ( 
	collection As IList(Of T),
	item As T
) As Integer

public:
generic<typename T>
static int BinarySearch(
	IList<T>^ collection, 
	T item
)

static member BinarySearch : 
        collection : IList<'T> * 
        item : 'T -> int

Parameters

collection: Type: System.Collections.GenericIListT
The collection to search.
item: Type: T
The item to find.

Type Parameters

T: The type of item in the collection.

Return Value

Type: Int32
The zero-based index of item in the sorted IList, if item is found; otherwise, a negative number that is the bitwise complement of the index of the next element that is larger than item or, if there is no larger element, the bitwise complement of Count.

Remarks

This method is similar to BinarySearch(T) or BinarySearchT(T, T) except that it operates on any type that implements IListT.
