Implements
IList<T>.IndexOf(T)Remarks
The collection is searched forward starting at the first item and ending at the last item in the collection.
This method determines equality using the default comparer Generic System.Collections.Generic.Comparer.Default. This comparer checks whether type T implements Generic System.IComparable and uses that implementation if available. If not, this comparer checks whether type T implements System.IComparable. If type T does not implement either interface, this method uses Equals(Object).
This method performs a linear search; therefore, the average execution time is proportional to Count. That is, this method is an O(n) operation, where n is Count.
