FindLastIndex Method

FindLastIndex<TTarget>()

Searches for an element that matches the conditions defined by the specified predicate, and returns the zero-based index of the last occurrence within the entire List<T>.

Declaration

public int FindLastIndex<TTarget>() where TTarget : T

Public Function FindLastIndex(Of TTarget As T)() As Integer

Returns

Type	Description
int	The zero-based index of the last occurrence of an element that matches the conditions defined by match, if found; otherwise, false.

Type Parameters

Name	Description
TTarget

FindLastIndex<TTarget>(Predicate<TTarget>)

Searches for an element that matches the conditions defined by the specified predicate, and returns the zero-based index of the last occurrence within the entire List<T>.

Declaration

public int FindLastIndex<TTarget>(Predicate<TTarget> match) where TTarget : T

Public Function FindLastIndex(Of TTarget As T)(match As Predicate(Of TTarget)) As Integer

Parameters

Type	Name	Description
Predicate<TTarget>	match	The Predicate<T> delegate that defines the conditions of the element to search for.

Returns

Type	Description
int	The zero-based index of the last occurrence of an element that matches the conditions defined by match, if found; otherwise, false.

Type Parameters

Name	Description
TTarget

Exceptions

Type	Condition
ArgumentNullException	match is null.

FindLastIndex<TTarget>(int, Predicate<TTarget>)

Searches for an element that matches the conditions defined by the specified predicate, and returns the zero-based index of the last occurrence within the range of elements in the List<T> that extends from the first element to the specified index.

Declaration

public int FindLastIndex<TTarget>(int startIndex, Predicate<TTarget> match) where TTarget : T

Public Function FindLastIndex(Of TTarget As T)(startIndex As Integer, match As Predicate(Of TTarget)) As Integer

Parameters

Type	Name	Description
int	startIndex	The zero-based starting index of the backward search.
Predicate<TTarget>	match	The Predicate<T> delegate that defines the conditions of the element to search for.

Returns

Type	Description
int	The zero-based index of the last occurrence of an element that matches the conditions defined by match, if found; otherwise, false.

Type Parameters

Name	Description
TTarget

Exceptions

Type	Condition
ArgumentOutOfRangeException	startIndex is outside the range of valid indexes for the List<T>.
ArgumentNullException	match is null.

FindLastIndex<TTarget>(int, int, Predicate<TTarget>)

Searches for an element that matches the conditions defined by the specified predicate, and returns the zero-based index of the last occurrence within the range of elements in the List<T> that contains the specified number of elements and ends at the specified index.

Declaration

public int FindLastIndex<TTarget>(int startIndex, int count, Predicate<TTarget> match) where TTarget : T

Public Function FindLastIndex(Of TTarget As T)(startIndex As Integer, count As Integer, match As Predicate(Of TTarget)) As Integer

Parameters

Type	Name	Description
int	startIndex	The zero-based starting index of the backward search.
int	count	The number of elements in the section to search.
Predicate<TTarget>	match	The Predicate<T> delegate that defines the conditions of the element to search for.

Returns

Type	Description
int	The zero-based index of the last occurrence of an element that matches the conditions defined by match, if found; otherwise, false.

Type Parameters

Name	Description
TTarget

Exceptions

Type	Condition
ArgumentOutOfRangeException	count is less than 0.
ArgumentNullException	match is null.
