System.Xml

Assembly:

System.Xml.ReaderWriter.dll

Source:

XmlNode.cs

Gets or sets the namespace prefix of this node.

public:
 virtual property System::String ^ Prefix { System::String ^ get(); void set(System::String ^ value); };

public virtual string Prefix { get; set; }

member this.Prefix : string with get, set

Public Overridable Property Prefix As String

Property Value

String

The namespace prefix of this node. For example, Prefix is bk for the element <bk:book>. If there is no prefix, this property returns String.Empty.

Exceptions

ArgumentException

This node is read-only.

XmlException

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".

Remarks

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.
