MemberInfo中的常量

我试图在我的类Car中获取有关常量的信息，但不幸的是，结果我只得到4个字段(名称，currentSpeed, maxSpeed，状态)。如何获取字段const.

谢谢。

public abstract class Car
{
    protected string name;
    protected short currentSpeed;
    protected short maxSpeed;
    protected EngineState state;
    protected const int const = 1;
 }

 Type type = assembly.GetType("CarLibrary.Car"); 
 MemberInfo[] members = type.GetMembers(BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public);
 foreach (MemberInfo element in members)
 Console.WriteLine("{0,-15}:  {1}", element.MemberType, element);

type.GetFields(BindingFlags.Static |
               BindingFlags.FlattenHierarchy)
    .Where(fi => fi.IsLiteral && !fi.IsInitOnly).ToList();
