Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).


If collection is neither an IListT of objects, IReadOnlyListT of objects, nor an IList implementation, then the collection will be iterated. In this case the checkBounds argument is ignored and the method returns if the index is invalid.
