autofac 一个接口多个实现的顺序执行

namespace AutofacTest.Interface
{
    public interface IUserInfo
    {
        string GetUserINfo(int uid);
        int sort();
    }
}

public class CrmUserInfoHelper : IUserInfo

        }

        public int sort()
        {
            return 2;
        }
    }

public class HrmUserInfoHelper : IUserInfo
    {
        public string GetUserINfo(int uid)
        {
            return "hrmuserinfo";
        }

        public int sort()//实现对多个实现的顺序执行
        {
            return 1;
        }
    }

            }
