XStreamingElement.ToString Method (SaveOptions)

Returns the XML for this streaming element, optionally disabling formatting.

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

'Declaration
Public Function ToString ( _
	options As SaveOptions _
) As String

Parameters

options
Type: System.Xml.Linq.SaveOptions

A SaveOptions that specifies formatting behavior.

Return Value

Type: System.String
A String containing the XML.

Note that when debugging a program that uses XStreamingElement, displaying the value of an object causes its ToString method to be called. This causes the XML to be serialized. If the semantics of your streaming element query are such that the streaming element can only be streamed once, this may cause undesirable behavior in your debugging experience.

The following example shows two uses of ToString. The first use preserves white space. The second one serializes the XStreamingElement with formatting.

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

Console.WriteLine(dstTree.ToString(SaveOptions.DisableFormatting))
Console.WriteLine("------")
Console.WriteLine(dstTree.ToString())

This example produces the following output:

<NewRoot><DifferentChild>3</DifferentChild></NewRoot>
------
<NewRoot>
  <DifferentChild>3</DifferentChild>
</NewRoot>
