Adds the specified content as children to this XStreamingElement.

public:
 void Add(System::Object ^ content);
public void Add (object content);
public void Add (object? content);
member this.Add : obj -> unit
Public Sub Add (content As Object)

Parameters

content
Object

Content to be added to the streaming element.

Examples

The following example creates a new XStreamingElement. It then adds two queries to the streaming element. The queries are not iterated until the streaming element is serialized.

XElement srcTree = new XElement("Root",
                       new XElement("Child", 1),
                       new XElement("Child", 2),
                       new XElement("Child", 3),
                       new XElement("Child", 4),
                       new XElement("Child", 5)
                   );

XStreamingElement dstTree = new XStreamingElement("NewRoot");

dstTree.Add(
    from el in srcTree.Elements()
    where (int)el <= 1
    select new XElement("Child", (int)el)
);

dstTree.Add(
    from el in srcTree.Elements()
    where (int)el >= 3
    select new XElement("DifferentChild", (int)el)
);

Console.WriteLine(dstTree);

Dim srcTree As XElement = _
    <Root>
        <Child>1</Child>
        <Child>2</Child>
        <Child>3</Child>
        <Child>4</Child>
        <Child>5</Child>
    </Root>

Dim dstTree As XStreamingElement = New XStreamingElement("NewRoot")

dstTree.Add( _
    From el In srcTree.Elements() _
    Where el.Value <= 1 _
    Select <Child><%= el.Value %></Child> _
)

dstTree.Add( _
    From el In srcTree.Elements() _
    Where el.Value >= 3 _
    Select <DifferentChild><%= el.Value %></DifferentChild> _
)

Console.WriteLine(dstTree)

This example produces the following output:

<NewRoot>
  <Child>1</Child>
  <DifferentChild>3</DifferentChild>
  <DifferentChild>4</DifferentChild>
  <DifferentChild>5</DifferentChild>
</NewRoot>

Remarks

This constructor adds the specified content and attributes to the XStreamingElement. While it is often possible to construct the XStreamingElement in a single statement, it is sometimes more convenient to add content to the streaming element incrementally.

Queries are not iterated until the XStreamingElement is serialized. This is in contrast to using queries for content for an XElement, where queries are iterated at the time of construction of the new XElement.

For details about the valid content that can be passed to this function, see Valid Content of XElement and XDocument Objects.
