	T value
)

Parameters

array: Type: System.Collections.Immutable::ImmutableArray<T>
The sorted array to search.

value: Type: T
The object to search for.

Return Value

Type: System::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.

Type Parameters
