CultureInfo.GetCultureInfo Method (Int32)
Retrieves a cached, read-only instance of a culture by using the specified culture identifier.
Assembly: mscorlib (in mscorlib.dll)
We recommend that you use the string overload of this method (GetCultureInfo(String)), because locale names should be used instead of LCIDs. For custom locales, the locale name is required.
If culture is the locale identifier of the current culture, the returned CultureInfo object does not reflect any user overrides.Notes to Callers
The .NET Framework 3.5 and earlier versions throw an ArgumentException if culture is not a valid culture identifier. Starting with the .NET Framework 4, this method throws a CultureNotFoundException. Starting with apps that run under the .NET Framework 4 or later on Windows 7 or later, the method attempts to retrieve a CultureInfo object whose identifier is culture from the operating system; if the operating system does not support that culture, the method throws a CultureNotFoundException.
