Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable(T). When you use instance method syntax to call this method, omit the first parameter.| Exception | Condition |

| ArgumentNullException | source is a null reference (Nothing in Visual Basic). |
Visual Basic users can use the integrated XML descendant axis to retrieve the descendant elements of a collection. However, the integrated axis only retrieves descendants with a specified name. If Visual Basic users want to retrieve all descendants, then they must use this axis method explicitly.
This method uses deferred execution.
