Syntax

public static class IListExtensions

Methods

BinarySearch<T>(IList<T>, int, int, T, IComparer<T>)

The class List<T> has a BinarySearch method but there is no out-of-the-box BinarySearch method available on IList<T> So here it is. Searches a sorted list for a specific element given a comparer which defines the ordering of the list.

Declaration

public static int BinarySearch<T>(this IList<T> list, int index, int count, T item, IComparer<T> comparer = null)

Parameters

Type	Name	Description
IList<T>	list	The list to search.
int	index	The starting index of the list to search.
int	count	The number of elements to search.
T	item	The item to search for.
IComparer<T>	comparer	The comparer corresponding to the ordering of the list, or null to use the default comparer.

Returns

Type	Description
int	The index of the item in the collection, if it is found. If it is not found then the result is the bitwise complement of the index (which will be negative) where such an item should be found.

Type Parameters

Name	Description
T	The list element type.

BinarySearch<T>(IList<T>, T, IComparer<T>)

Searches a sorted list for a specific element given a comparer which defines the ordering of the list.

Declaration

public static int BinarySearch<T>(this IList<T> list, T item, IComparer<T> comparer = null)

Parameters

Type	Name	Description
IList<T>	list	The list to search.
T	item	The item to search for.
IComparer<T>	comparer	The comparer corresponding to the ordering of the list, or null to use the default comparer.

Returns

Type	Description
int	The index of the item in the collection, if it is found. If it is not found then the result is the bitwise complement of the index (which will be negative) where such an item should be found.

Type Parameters

Name	Description
T	The list element type.

InsertSorted<T>(IList<T>, T, IComparer<T>)

Insert an item into an IList in sorted order, assuming the list of already sorted.

Declaration

public static void InsertSorted<T>(this IList<T> items, T item, IComparer<T> comparer)

Parameters

Type	Name	Description
IList<T>	items	The list.
T	item	The item to insert.
IComparer<T>	comparer	The comparison operator.

Type Parameters

Name	Description
T	The type of the items.

SwapPositions<T>(IList<T>, int, int)

Swaps the positions of two elements within an IList.

Declaration

public static void SwapPositions<T>(this IList<T> items, int indexA, int indexB)

Parameters

Type	Name	Description
IList<T>	items	The list.
int	indexA	The index of one of the elements you wish to swap.
int	indexB	The index of the other element you wish to swap.

Type Parameters

Name	Description
T	The type of the items.
