XmlAnyElementAttribute.Namespace Property

Gets or sets the XML namespace generated in the XML document.

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

public string Namespace { get; set; }

Property Value

Type: System.String
An XML namespace.

The Namespace property allows you to set a unique name for the XML attribute. The Namespace property conforms to the rules for creating an XML namespace as found in the World Wide Web Consortium ( document, "Namespaces in XML."

To set the Namespace property to a prefixed name, create an XmlSerializerNamespaces that contains the namespaces and prefixes used in the XML document. Set the Namespace property to one of the namespaces in the XmlSerializerNamespaces. When the XML is generated, the attribute name is correctly prefixed with the prefix associated with the specified namespace.
