NumberFormatInfo.InvariantInfo Property

Gets the default read-only NumberFormatInfo that is culture-independent (invariant).

Namespace: System.Globalization
Assembly: mscorlib (in mscorlib.dll)

public static NumberFormatInfo InvariantInfo { get; }
/** @property */
public static NumberFormatInfo get_InvariantInfo ()

public static function get InvariantInfo () : NumberFormatInfo

Property Value

The default read-only NumberFormatInfo that is culture-independent (invariant).

This property does not change, regardless of the current culture.

The following code example displays the default property values of the InvariantInfo.

      // Displays the default values for each of the properties.
      Console.WriteLine( "InvariantInfo:\nNote: Symbols might not display correctly on the console,\ntherefore, Unicode values are included." );
