If name is the name of the current culture, the returned CultureInfo object does not reflect any user overrides. This makes the method suitable for server applications or tools that do not have a real user account on the system and that need to load multiple cultures efficiently.
If name is String.Empty, the method returns the invariant culture. This is equivalent to retrieving the value of the InvariantCulture property.
Notes to Callers
The .NET Framework version 3.5 and earlier versions throw an ArgumentException if name is not a valid culture name. Starting with the .NET Framework version 4, this method throws a CultureNotFoundException.
