Extensions.Elements<T> Method (IEnumerable<T>)

Returns a collection of the child elements of every element and document in the source collection.

Namespace:  System.Xml.Linq
Assembly:  System.Xml.Linq (in System.Xml.Linq.dll)

public static IEnumerable<XElement> Elements<T>(
	this IEnumerable<T> source
)
where T : XContainer

Type Parameters

T

The type of the objects in source, constrained to XContainer.

Parameters

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

An IEnumerable<T> of XElement of the child elements of every element or document in the source collection.

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.

ExceptionCondition
ArgumentNullException

source is null.

Although Visual Basic contains an integrated elements axis that allows you to find all child elements with a specified XName for every element in the source collection, there is no integrated elements axis that allows you to retrieve a collection of every child element for every element in the source collection.

This method uses deferred execution.
