Writes this node to an XmlWriter.

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

Syntax

'Declaration
Public MustOverride Sub WriteTo ( _
    writer As XmlWriter _
)

public abstract void WriteTo(
    XmlWriter writer
)

Parameters

writer
Type: System.Xml.XmlWriter
An XmlWriter into which this method will write.

Remarks

You can use this method to write code that does a streaming transform of a very large document. For more information, see How to: Perform Streaming Transform of Large XML Documents in the .NET Framework documentation.

Examples

The following example creates an XmlWriter that writes to a StringBuilder. It then uses this method to write two XML trees to the writer.

Dim output As New StringBuilder
Dim sb As StringBuilder = New StringBuilder()
Dim xws As XmlWriterSettings = New XmlWriterSettings()
xws.OmitXmlDeclaration = True
xws.Indent = True

Using xw = XmlWriter.Create(sb, xws)
    xw.WriteStartElement("Root")
    Dim child1 As XElement = <Child>
                                 <GrandChild>some content</GrandChild>
                             </Child>
    child1.WriteTo(xw)
    Dim child2 As XElement = <AnotherChild>
                                 <GrandChild>different content</GrandChild>
                             </AnotherChild>
    child2.WriteTo(xw)
    xw.WriteEndElement()
End Using

output.Append(sb.ToString())
output.Append(Environment.NewLine)

OutputTextBlock.Text = output.ToString()

StringBuilder output = new StringBuilder();
StringBuilder sb = new StringBuilder();
XmlWriterSettings xws = new XmlWriterSettings();
xws.OmitXmlDeclaration = true;
xws.Indent = true;

using (XmlWriter xw = XmlWriter.Create(sb, xws))
{
    xw.WriteStartElement("Root");
    XElement child1 = new XElement("Child",
        new XElement("GrandChild", "some content")
    );
    child1.WriteTo(xw);
    XElement child2 = new XElement("AnotherChild",
        new XElement("GrandChild", "different content")
    );
    child2.WriteTo(xw);
    xw.WriteEndElement();
}
output.Append(sb.ToString() + Environment.NewLine);

OutputTextBlock.Text = output.ToString();
