- source
- Type: System.Collections.Generic::IEnumerable<T>
An IEnumerable<T> of XContainer that contains the source collection.

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 nullptr. |
This axis extension method is used on XDocument and XElement objects. Both of these types derive from XContainer, so this method operates on an IEnumerable<T> of XContainer that contains the source collection.
Although Visual Basic has an integrated XML axis for descendant elements, there is no integrated axis for descendant nodes, so Visual Basic users must use this axis method explicitly.
This method uses deferred execution.
