Gets or sets the namespace prefix of this node.
Assembly: System.Xml (in System.Xml.dll)
This node is read-only.
The specified prefix contains an invalid character.
The specified prefix is malformed.
The specified prefix is "xml" and the namespaceURI of this node is different from "http://www.w3.org/XML/1998/namespace".
This node is an attribute and the specified prefix is "xmlns" and the namespaceURI of this node is different from "http://www.w3.org/2000/xmlns/ ".
This node is an attribute and the qualifiedName of this node is "xmlns".
Setting this property, when permitted, changes the Name property, which holds the qualified name, on Element and Attribute nodes. Setting this property on node types that cannot have a prefix (such as Text, Comment, EntityReference, CDATA, ProcessingInstruction, Document, and DocumentFragment) has no effect. Changing the prefix of an attribute that is known to have a default value, does not make a new attribute with the default value and the original prefix appear, since the namespace URI and local name do not change.
Notes to Inheritors:
When overriding Prefix in a derived class, this property cannot be set.
