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

Public Function LastIndexOf (item As T, index As Integer, count As Integer, equalityComparer As IEqualityComparer(Of T)) As Integer

Parameters

item: T

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

index: Int32

The zero-based starting index of the backward search.

count: Int32

The number of elements in the section to search.

equalityComparer: IEqualityComparer<T>

The equality comparer to use in the search.

Returns

Int32

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

Implements

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