Dapper 嵌套对象查询

我有这样一个一对一关系的表结构：User->UserInfo

User:

 /// <summary>

	/// 用户

	/// </summary>

	[Serializable]

	public partial class SysUser

	{

		public SysUser()

		{}

		#region Model

		/// <summary>

		/// 用户编号

		/// </summary>

		public string SysId { get; set; }



		/// <summary>

		/// 用户名

		/// </summary>

		public string UserName { get; set; }



		/// <summary>

		/// 密码

		/// </summary>

		public string UserPwd { get; set; }



		/// <summary>

		/// 创建时间

		/// </summary>

		public DateTime? CreateTime { get; set; }



		/// <summary>

		/// 最后一次登录时间

		/// </summary>

		public DateTime? LastLogin { get; set; }



		/// <summary>

		/// 该条记录的操作情况，用于记录最后一次谁在什么时候创建、修改了该记录

		/// </summary>

		public string RecordStatus { get; set; }



        /// <summary>

        /// 用户的详细信息

        /// </summary>

        public SysUserInfo UserInfo { get; set; }

         

		#endregion Model



        public IEnumerable<SysRole> Roles { get; set; }

	}

 

UserInfo:

/// <summary>

	/// 用户信息

	/// </summary>

	[Serializable]

	public partial class SysUserInfo

	{

		public SysUserInfo()

		{}

		#region Model

		/// <summary>

		/// 用户编号

		/// </summary>

		public string SysId { get; set; }



		/// <summary>

		/// 真实名字

		/// </summary>

		public string RealName { get; set; }



		/// <summary>

		/// 职位

		/// </summary>

		public string Title { get; set; }



		/// <summary>

		/// 性别

		/// </summary>

		public bool Sex { get; set; }



		/// <summary>

		/// 手机

		/// </summary>

		public string Phone { get; set; }



		/// <summary>

		/// 传真

		/// </summary>

		public string Fax { get; set; }



		/// <summary>

		/// 邮箱

		/// </summary>

		public string Email { get; set; }



		/// <summary>

		/// qq

		/// </summary>

		public string QQ { get; set; }



		/// <summary>

		/// 地址

		/// </summary>

		public string Address { get; set; }



		#endregion Model



	}

 

 

查询的具体Sql：

select u.CreateTime,u.LastLogin,u.RecordStatus,u.SysId,u.UserName,u.UserPwd,ui.SysId,

	   ui.Address,ui.Email,ui.Fax,ui.Phone,ui.QQ,ui.RealName,ui.Sex,ui.Title

from Sys_User u inner join Sys_UserInfo ui on u.SysId=ui.SysId inner join Sys_UserRole ur on 

u.SysId=ur.UserId inner join Sys_Role r on ur.RoleId = r.SysId 

 

要想把UserInfo的数据填充到User中，需要用下面的方式实现：

connection.Query<SysUser, SysUserInfo, SysUser>(
                    Constant.ProcGetList,
                    (u, ui) =>
                        {
                            u.UserInfo = ui;
                            return u;
                        },
                        p,splitOn:"SysId",
                    commandType: CommandType.StoredProcedure);

 

 

此处要注意的就是splitOn，他其它是分割子对象的属性。
