Searches for the specified object and returns the zero-based index of the first occurrence within the range of elements in the IImmutableList<T> that starts at the specified index and contains the specified number of elements.
public:
int IndexOf(T item, int index, int count, System::Collections::Generic::IEqualityComparer<T> ^ equalityComparer);
public int IndexOf (T item, int index, int count, System.Collections.Generic.IEqualityComparer<T> equalityComparer);
public int IndexOf (T item, int index, int count, System.Collections.Generic.IEqualityComparer<T>? equalityComparer);

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 IImmutableList<T>. This value can be null for reference types.
- index
- Int32
The zero-based starting indexes 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 to locate item
.
Returns
The zero-based index of the first occurrence of item
within the range of elements in the IImmutableList<T> that starts at index
and contains count
number of elements if found; otherwise -1.
