public class para
    {
        public int id { get; set; }
        public string  s { get; set; }
    }

------解决方案--------------------
不好意思，没看清楚，写个全的
C# code

public class userList//定义一个userList类
        {
            public int ID { get; set; }
            public string userName { get; set; }
            public userList()
            {
            }
            public userList(int id, string name)
            {
                ID = id;
                userName = name;
            }
        }
