	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)

Remarks

The XmlSerializerNamespaces contains a collection of XML namespaces, each with an associated prefix. The XmlSerializer uses an instance of the XmlSerializerNamespaces class to create qualified names in an XML document.

XML namespaces contained by the XmlSerializerNamespaces must conform to the www.w3.org specification, Namespaces in XML.

XML namespaces provide a way to qualify the names of XML elements and attributes in XML documents. A qualified name consists of a prefix and a local name, separated by a colon. The prefix functions only as a placeholder; it is mapped to a URI that specifies a namespace. The combination of the universally-managed URI namespace and the local name produces a name that is guaranteed to be universally unique.

To create qualified names in an XML document:

Create an XmlSerializerNamespaces instance.
Add each prefix and namespace pair that you want to the instance.
Apply the appropriate .NET attribute to each property or class that the XmlSerializer serializes into an XML document. The available attributes are:

Set the Namespace property of each attribute to one of the namespace values from the XmlSerializerNamespaces object.
Pass the XmlSerializerNamespaces to the Serialize method of the XmlSerializer.

Note:
The creation of an empty namespace and prefix pair is not supported. That is, you cannot create a pair using the following code.

XmlSerializerNamespaces ns = new XmlSerializerNamespaces(); 
ns.Add("", "");

Dim ns As XmlSerializerNamespaces ns = New XmlSerializerNamespaces()
ns.Add("", "")
