IndexOf<T>(IImmutableList<T>, T, Int32)

Source:

ImmutableList.cs

Searches for the specified object and returns the zero-based index of the first occurrence within the range of elements in the immutable list that extends from the specified index to the last element.

public:
generic <typename T>
[System::Runtime::CompilerServices::Extension]
 static int IndexOf(System::Collections::Immutable::IImmutableList<T> ^ list, T item, int startIndex);

public static int IndexOf<T> (this System.Collections.Immutable.IImmutableList<T> list, T item, int startIndex);

static member IndexOf : System.Collections.Immutable.IImmutableList<'T> * 'T * int -> int

<Extension()>
Public Function IndexOf(Of T) (list As IImmutableList(Of T), item As T, startIndex As Integer) As Integer

Type Parameters

T

The type of items in the list.

Parameters

list

IImmutableList<T>

The list to search.

item

T

The object to locate in the Immutable list. The value can be null for reference types.

startIndex

Int32

The zero-based starting index of the search. 0 (zero) is valid in an empty list.

Returns

Int32

The zero-based index of the first occurrence of item within the range of elements in the Immutable list that extends from index to the last element, if found; otherwise, -1.

Type Parameters

T

The type of items in the list.

Parameters

list

IImmutableList<T>

The list to search.

item

T

The object to locate in the Immutable list. The value can be null for reference types.

startIndex

Int32

The zero-based starting index of the search. 0 (zero) is valid in an empty list.

count

Int32

The number of elements in the section to search.

Returns

Int32

The zero-based index of the first occurrence of item within the range of elements in the Immutable list that extends from index to the last element, if found; otherwise, -1.
