Definition

Namespace:
System.Collections.Immutable
Assembly:
System.Collections.Immutable.dll

Overloads

LastIndexOf(T)

Searches for the specified object and returns the zero-based index of the last occurrence within the entire immutable list.
LastIndexOf(T, Int32)

Searches for the specified object and returns the zero-based index of the last occurrence within the range of elements in the immutable list that extends from the first element to the specified index.
LastIndexOf(T, Int32, Int32)

Searches for the specified object and returns the zero-based index of the last occurrence within the range of elements in the immutable list that contains the specified number of elements and ends at the specified index.
LastIndexOf(T, Int32, Int32, IEqualityComparer<T>)

Searches for the specified object and returns the zero-based index of the last occurrence within the range of elements in the immutable list that contains the specified number of elements and ends at the specified index.

LastIndexOf(T)

Searches for the specified object and returns the zero-based index of the last occurrence within the entire immutable list.

public:
 int LastIndexOf(T item);
public int LastIndexOf (T item);
member this.LastIndexOf : 'T -> int
Public Function LastIndexOf (item As T) As Integer

Parameters

item
T

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

Returns

Int32

The zero-based index of the last occurrence of item within the entire immutable list, if found; otherwise, -1.

Applies to

LastIndexOf(T, Int32)

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

public:
 int LastIndexOf(T item, int startIndex);
public int LastIndexOf (T item, int startIndex);
member this.LastIndexOf : 'T * int -> int
Public Function LastIndexOf (item As T, startIndex As Integer) As Integer

Parameters

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 backward search.

Returns

Int32

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

Applies to

LastIndexOf(T, Int32, Int32)

Searches for the specified object and returns the zero-based index of the last occurrence within the range of elements in the immutable list that contains the specified number of elements and ends at the specified index.

public:
 int LastIndexOf(T item, int startIndex, int count);
public int LastIndexOf (T item, int startIndex, int count);
member this.LastIndexOf : 'T * int * int -> int
Public Function LastIndexOf (item As T, startIndex As Integer, count As Integer) As Integer

Parameters

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 backward search.

count
Int32

The number of elements in the section to search.

Returns

Int32

The zero-based index of the last occurrence of item within the range of elements in the immutable list that contains count number of elements and ends at index, if found; otherwise, -1.

Applies to

LastIndexOf(T, Int32, Int32, IEqualityComparer<T>)

Searches for the specified object and returns the zero-based index of the last occurrence within the range of elements in the immutable list that contains the specified number of elements and ends at the specified index.

public:
 int LastIndexOf(T item, int startIndex, int count, System::Collections::Generic::IEqualityComparer<T> ^ equalityComparer);
public int LastIndexOf (T item, int startIndex, int count, System.Collections.Generic.IEqualityComparer<T> equalityComparer);
public int LastIndexOf (T item, int startIndex, int count, System.Collections.Generic.IEqualityComparer<T>? equalityComparer);
member this.LastIndexOf : 'T * int * int * System.Collections.Generic.IEqualityComparer<'T> -> int
Public Function LastIndexOf (item As T, startIndex As Integer, count As Integer, equalityComparer As IEqualityComparer(Of T)) As Integer

Parameters

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 to search.

equalityComparer
IEqualityComparer<T>

The value comparer to use for comparing elements for equality.

Returns

Int32

The zero-based index of the first occurrence of item within the range of elements in the immutable list that starts at index and contains count number of elements, if found; otherwise, -1
