XmlDocument.Save Method (Stream)

Saves the XML document to the specified stream.

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

public virtual void Save(
	Stream outStream
)

Parameters

outStream
Type: System.IO.Stream

The stream to which you want to save.

ExceptionCondition
XmlException

The operation would not result in a well formed XML document (for example, no document element or duplicate XML declarations).

White space is preserved only if PreserveWhitespace is set to true.

The XmlDeclaration of the current XmlDocument object determines the encoding attribute in the saved document. The value of the encoding attribute is taken from the XmlDeclaration.Encoding property. If the XmlDocument does not have an XmlDeclaration, or if the XmlDeclaration does not have an encoding attribute, the saved document will not have one either.

When the document is saved, xmlns attributes are generated to persist the node identity (local name + namespace URI) correctly. For example, the following C# code

 XmlDocument doc = new XmlDocument();
 doc.AppendChild(doc.CreateElement("item","urn:1"));
 doc.Save(Console.Out);

generates this xmls attribute <item xmls="urn:1"/>.

This method is a Microsoft extension to the Document Object Model (DOM).

Note that only the Save method enforces a well-formed XML document. All other Save overloads only guarantee a well-formed fragment.
