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
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.
