XmlLanguage Class

XmlLanguage Class

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

Represents culture information for use in XML and XAML markup.


Namespace:  System.Windows.Markup
Assembly:  System.Windows (in System.Windows.dll)
XMLNS for XAML: Not mapped to an xmlns.

public sealed class XmlLanguage
<object property="prefix"/>
- or -
<object property="prefix-subcode"/>

XAML Values


Language prefix, using the ISO 639-1 language prefix values. For example en, or zh. Uppercase values are accepted and converted to lowercase. This may also be an empty attribute, "".


If provided, must be preceded by a single hyphen. Then, a subcode as defined by RFC 3066. The most typical usage, and the one which is most likely to properly map to a CultureInfo, is a country or regional designation such as -us or -hk. Uppercase values are accepted and converted to lowercase.

The XmlLanguage type exposes the following members.

Public propertyIetfLanguageTagGets the string representation of the language tag.

Public methodEqualsChecks for equality of an object to the current object. (Overrides Object.Equals(Object).)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for the XmlLanguage class. (Overrides Object.GetHashCode().)
Public methodStatic memberGetLanguageReturns a XmlLanguage instance, based on a string representing the language per RFC 3066.
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Public operatorStatic memberEqualityDetermines whether two specified XmlLanguage objects have the same value.
Public operatorStatic memberInequalityDetermines whether two specified XmlLanguage objects have a different value.

The culture information may or may not have a registered CultureInfo present on the system where the XML is interpreted.

This class is useful for dealing with values represented using xml:lang in XML.

Note that the XML specification allows the empty string for xml:lang, although that is not permitted by RFC 3066; therefore, this type permits "" (empty attribute string). A default-constructed XmlLanguage behaves as if constructed with "" (empty string).

In general, the construction syntax for XmlLanguage in XAML and code parallels the constructor syntax for CultureInfo, at least in terms of the meaning of the input string.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
