如何让所有实体类用相同名称的主键（很有力的问题，比如所有表实体主键都用ＩＤ）

    /// <summary>

    /// 实体模块统一接口

    /// </summary>

    public interface IEntity

    {

        /// <summary>

        /// 为了主键统一，而手动设置的

        /// </summary>

        string ID { get; }

    }

    public class Race : IEntity

    {

        public int Id { get; set; }

        public string Name { get; set; }

        #region IEntity Members

        public string ID

        {

            get { return Id.ToString(); }

        }

        #endregion

    }

 class bobo<TEntity> where TEntity : class,IEntity

    {

        public void hello(TEntity entity)

        {

            Console.WriteLine("\n\r共同的主键值是："+entity.ID);

        }

    }

  bobo<Race> b = new bobo<Race>();

  b.hello(new Race { Id = 1, Name = "zzl" });
