XStreamingElement.ToString Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Returns the formatted (indented) XML for this streaming element.

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

Syntax

'Declaration
Public Overrides Function ToString As String
public override string ToString()

Return Value

Type: System.String
A String containing the indented XML.

Remarks

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.

Examples

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

Dim output As New StringBuilder
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> _
                    )

output.Append(dstTree.ToString(SaveOptions.DisableFormatting))
output.Append(Environment.NewLine)
output.Append("------")
output.Append(Environment.NewLine)
output.Append(dstTree.ToString())
output.Append(Environment.NewLine)

OutputTextBlock.Text = output.ToString()
StringBuilder output = new StringBuilder();
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",
                        from el in srcTree.Elements()
                        where (int)el == 3
                        select new XElement("DifferentChild", (int)el)
                    );

output.Append(dstTree.ToString(SaveOptions.DisableFormatting) + Environment.NewLine);
output.Append("------" + Environment.NewLine);
output.Append(dstTree.ToString() + Environment.NewLine);

OutputTextBlock.Text = output.ToString();
