Public Function IndexOf (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 search. 0 (zero) is valid in an empty list.

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