[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Returns the XML for this streaming element, optionally disabling formatting.
Assembly: System.Xml.Linq (in System.Xml.Linq.dll)
Parameters
- options
- Type: System.Xml.Linq.SaveOptions
A SaveOptions that specifies formatting behavior.
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 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()
