Using the InvariantCulture Property

The CultureInfo.InvariantCulture property is neither a neutral nor a specific culture. It is a third type of culture that is culture-insensitive. It is associated with the English language but not with a country or region. You can use InvariantCulture in almost any method in the System.Globalization namespace that requires a culture.

  // Parses the string stored in the file,
         // and stores it in a DateTime.
         DateTime dtout = DateTime.Parse(date, InvC);

         // Creates a CultureInfo set to "fr-FR".
         CultureInfo frc = new CultureInfo("fr-FR");
         // Displays the date formatted for the "fr-FR" culture.
         Console.WriteLine("\nThe date read from the file and formatted 
               for the culture \"fr-FR\" is:\n{0}" , dtout.ToString("d", 
               frc));

         // Creates a CultureInfo set to "ja-JP".
         CultureInfo jpn= new CultureInfo("ja-JP");
         // Displays the date formatted for the "ja-JP" culture.
         Console.WriteLine("\nThe date read from the file and formatted 
               for the culture \"ja-JP\" is:\n{0}" , dtout.ToString("d", 
               jpn));

The date read from the file and formatted for the culture "fr-FR" is:
24/07/2001

The date read from the file and formatted for the culture "ja-JP" is:
2001/07/24
