  public static void Main(String[] argv){  
    double value = 12345.67891;

    CultureInfo culture;
    
    // Use standard numeric format specifiers.
    specifier = "G";
    culture = CultureInfo.CreateSpecificCulture("eu-ES");
    Console.WriteLine(value.ToString(specifier, culture));
    Console.WriteLine(value.ToString(specifier, CultureInfo.InvariantCulture));

    
    specifier = "C";
    culture = CultureInfo.CreateSpecificCulture("en-US");
    Console.WriteLine(value.ToString(specifier, culture));
    culture = CultureInfo.CreateSpecificCulture("en-GB");
    Console.WriteLine(value.ToString(specifier, culture));

    
    specifier = "E04";
    culture = CultureInfo.CreateSpecificCulture("sv-SE");
    Console.WriteLine(value.ToString(specifier, culture));
    culture = CultureInfo.CreateSpecificCulture("en-NZ");
    Console.WriteLine(value.ToString(specifier, culture));
    
    specifier = "F";
    culture = CultureInfo.CreateSpecificCulture("fr-FR");
    Console.WriteLine(value.ToString(specifier, culture));
    culture = CultureInfo.CreateSpecificCulture("en-CA");
    Console.WriteLine(value.ToString(specifier, culture));
    
    specifier = "N";
    culture = CultureInfo.CreateSpecificCulture("es-ES");
    Console.WriteLine(value.ToString(specifier, culture));
    culture = CultureInfo.CreateSpecificCulture("fr-CA");
    Console.WriteLine(value.ToString(specifier, culture));

    
    specifier = "P";
    culture = CultureInfo.InvariantCulture;
    Console.WriteLine((value/10000).ToString(specifier, culture));
    culture = CultureInfo.CreateSpecificCulture("ar-EG");
    Console.WriteLine((value/10000).ToString(specifier, culture));
  }
}

The code above generates the following result.
