BinarySearch<T>(ImmutableArray<T>, T)

Source:

ImmutableArray.cs

Searches the sorted immutable array for a specified element using the default comparer and returns the zero-based index of the element, if it's found.

public:
generic <typename T>
[System::Runtime::CompilerServices::Extension]
 static int BinarySearch(System::Collections::Immutable::ImmutableArray<T> array, T value);

public static int BinarySearch<T> (this System.Collections.Immutable.ImmutableArray<T> array, T value);

static member BinarySearch : System.Collections.Immutable.ImmutableArray<'T> * 'T -> int

<Extension()>
Public Function BinarySearch(Of T) (array As ImmutableArray(Of T), value As T) As Integer

Type Parameters

T

The type of element stored in the array.

Parameters

array

ImmutableArray<T>

The sorted array to search.

value

T

The object to search for.

Returns

Int32

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

Exceptions

InvalidOperationException

value does not implement IComparable or the search encounters an element that does not implement IComparable.

Type Parameters

T

Parameters

array

ImmutableArray<T>

value

T

The object to search for.

comparer

IComparer<T>

The comparer implementation to use when comparing elements, or null to use the default comparer.

Returns

Int32

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

Exceptions

InvalidOperationException

comparer is null and value does not implement IComparable or the search encounters an element that does not implement IComparable.

BinarySearch<T>(ImmutableArray<T>, Int32, Int32, T)

Type Parameters

T

The type of element stored in the array.

Parameters

array

The sorted array to search.

index

Int32

The starting index of the range to search.

length

Int32

The length of the range to search.

value

T

The object to search for.

Returns

Int32

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

Exceptions

InvalidOperationException

value does not implement IComparable or the search encounters an element that does not implement IComparable.

ArgumentException

index and length do not specify a valid range in array.

ArgumentOutOfRangeException

index is less than the lower bound of array.

-or-

length is less than zero.
