Getting the Enums Description

Some times we need to enums for strongly typed strings in place of normal string values. But while displaying the enums we need the space between two words at that time we uses the enum description as follows
public enum MenuOptions
{
[Description("Park Vehicle")]
ParkVehicle = 1,
[Description("Exit Vehicle")]
ExitVehicle = 2,
[Description("Check Slot is Empty")]
CheckSlotIsEmpty = 3,
[Description("Parked Vehicles List")]
ParkedVehiclesList = 4,
[Description("Exit")]
Exit = 5
}

Code to get the Enum Description:
public String GetEnumDescription(Enum value)
{
FieldInfo fi = value.GetType().GetField(value.ToString());
DescriptionAttribute[] attributes =
(DescriptionAttribute[])fi.GetCustomAttributes
(typeof(DescriptionAttribute), false);
return (attributes.Length > 0) ? attributes[0].Description : value.ToString();
}

The usage of enum description as follows
public static void GetNavigation()
{
foreach (int i in Enum.GetValues(typeof(MenuOptions)))
Console.WriteLine("{0}. {1}", i,GetEnumDescription((Enum)Enum.Parse(typeof(MenuOptions),Enum.GetName(typeof(MenuOptions), i))));
}
