Property Value  Type: System.Globalization.CultureInfo The
object that is culture-independent (invariant).  The invariant
culture is culture-insensitive; it is associated with the
English language but not with any country/region. You specify
the invariant culture by name by using an empty string ("") in
the call to a CultureInfo instantiation method.
CultureInfo.InvariantCulture also retrieves an instance of the
invariant culture. It can be used in almost any method in the
System.Globalization namespace that requires a culture. The
objects returned by properties such as CompareInfo,
DateTimeFormat, and NumberFormat also reflect the string
comparison and formatting conventions of the invariant culture.
String Operations  You can use the invariant culture for culture
