Save Method (TextWriter)

XStreamingElement.Save Method (TextWriter)

 

Serialize this streaming element to a TextWriter.

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

public void Save(
	TextWriter textWriter
)

Parameters

textWriter
Type: System.IO.TextWriter

A TextWriter that the XStreamingElement will be written to.

The serialized XML will be indented. All insignificant white space will be removed, and additional white space will be added so that the XML will be properly indented. The behavior of this method is that insignificant white space nodes in the XML tree will not be preserved.

If you want to control white space, use one of the overloads of Save that take SaveOptions as a parameter. For more information, see Preserving White Space while Loading or Parsing XML and Preserving White Space While Serializing.

The following example creates a source XML tree, then instantiates an XStreamingElement using a query on the source XML tree. It then writes the streaming element to a StringWriter.


                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)
                    );

StringBuilder sb = new StringBuilder();
dstTree.Save(new StringWriter(sb));
Console.WriteLine(sb.ToString());

This example produces the following output:


                <?xml version="1.0" encoding="utf-16"?>
<NewRoot>
  <DifferentChild>3</DifferentChild>
  <DifferentChild>4</DifferentChild>
  <DifferentChild>5</DifferentChild>
</NewRoot>
