Syntax

'Declaration
Public Shared Function GetLanguage ( _
    ietfLanguageTag As String _
) As XmlLanguage

public static XmlLanguage GetLanguage(
    string ietfLanguageTag
)

Parameters

  • ietfLanguageTag
    Type: System.String
    An RFC 3066 language string, or an empty string ("").

A new XmlLanguage with the provided string as its IetfLanguageTag value.

Exception Condition

Remarks

This method is effectively the constructor, and also supports the type conversion for XAML attribute usage.

The language string may be empty, or else must conform to RFC 3066 rules:

  • The first subtag must consist of only ASCII letters.

  • Additional subtags must consist of ASCII letters or numerals.

  • Subtags are separated by a single hyphen character.

  • Every subtag must be 1 to 8 characters long.

  • No leading or trailing hyphens are permitted.

By default an XmlLanguage has an empty value for its language component.
