[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

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

- Type: System.Xml.XmlNameTable
The XmlNameTable to use.
| Exception | Condition |

| NullReferenceException | nameTableis Nothing. |
The name table is used to look up prefixes and namespaces. An existing name table with pre-atomized strings can be specified in the constructor. There are several advantages in doing so. For example, if the name table of an XmlReader object is used, after each read, any namespace and prefix strings pushed into the name table can be re-used by XmlNamespaceManager.
For more information on atomized strings, see XmlNameTable.

If you specify an existing name table, any namespaces in the name table are not automatically added to XmlNamespaceManager. You must use AddNamespace and RemoveNamespace to add or remove namespaces. |
