MVC常见的控制器，接口，数据层之间的操作

user_books_info 类

namespace CiWong.LearningLevel.Mapping
{public class user_books_info{/// <summary>/// 使用对象ID,个人版存放会员ID，班级版存放班级ID，校园版存放校园ID/// </summary>public long user_id { get; set; }/// <summary>/// 购买类型(1=个人版，2=班级版，3=学校版)/// </summary>public Int16 purchase_type { get; set; }/// <summary>/// 题册ID/// </summary>public long book_id { get; set; }/// <summary>/// 课本名称/// </summary>public string book_name { get; set; }/// <summary>/// 课本封面/// </summary>public string book_cover { get; set; }/// <summary>/// 使用对象名称/// </summary>public string user_name { get; set; }/// <summary>/// 使用类型(0=试用，1=已购买，2=赠送，3=校本课程)/// </summary>public int use_mode { get; set; }/// <summary>/// 添加时间/// </summary>public DateTime create_time { get; set; }/// <summary>/// 首次购买时间/// </summary>public DateTime bourght_time { get; set; }/// <summary>/// 最后一次续费时间/// </summary>public DateTime last_paid_time { get; set; }/// <summary>/// 过期时间/// </summary>public DateTime expire_date { get; set; }}
}

　　

 

1，数据操作层（List<>）

 

/// <summary>/// 获取我购买的书籍/// </summary>/// <param name="userID"></param>/// <param name="pageIndex">页码</param>/// <param name="pageSize">条数</param>/// <returns></returns>public List<user_books_info> UserBookInfoGetByUserID(int userID, int pageIndex, int pageSize){List<user_books_info> bookList = new List<user_books_info>();string sql = @"CALL learn_user_books_info_getbyuserid(@UserID,@pageIndex,@pageSize);";MySqlParameter[] para = new MySqlParameter[]                                    {  new MySqlParameter("@UserID", userID),new MySqlParameter("@pageIndex", pageIndex),new MySqlParameter("@pageSize", pageSize)};using (var dr = MySqlHelper.ExecuteReader(DatabaseManager.Retrieve("wc_learninglevel_read"), sql, para)){while (dr.Read()){var bookInfo = new user_books_info();bookInfo.user_id = dr.GetInt32("user_id");bookInfo.purchase_type = dr.GetInt16("purchase_type");bookInfo.book_id = dr.GetInt64("book_id");bookInfo.book_name = dr.GetString("book_name");bookInfo.book_cover = dr.GetString("book_cover");bookInfo.user_name = dr.GetString("user_name");bookInfo.use_mode = dr.GetInt32("use_mode");bookInfo.create_time = dr.GetDateTime("create_time");bookInfo.bourght_time = dr.GetDateTime("bourght_time");//bookInfo.last_paid_time = dr.GetDateTime("last_paid_time");bookInfo.expire_date = dr.GetDateTime("expire_date");bookList.Add(bookInfo);}dr.Close();}return bookList;}

　　

2，数据调用接口层(List<>)

  

        /// <summary>/// 获取我购买的书籍/// </summary>/// <param name="userID"></param>/// <param name="pageIndex">页码</param>/// <param name="pageSize">条数</param>/// <returns></returns>List<user_books_info> UserBookInfoGetByUserID(int userID, int pageIndex, int pageSize);    

　　

3，控制器

   

ViewBag.UserLearns = this._Repository.UserBookInfoGetByUserID(userID, 1, 11);//购买的书籍

 

A, 数据操作层（IEnumerable<>）

   

        /// <summary>/// 获取文章列表 /// </summary>/// <param name="userID">用户ID</param>/// <param name="totalItem">总数据量</param>/// <param name="pageIndex">当前页</param>/// <param name="pageSize">每页数量</param>/// <param name="IsDelete">删除状态</param>/// <returns></returns>public IEnumerable<BlogContent> GetBlogContents(int userID, ref int totalItem, int pageIndex = 1, int pageSize = 20, bool IsFriend = false, bool IsManager = false){List<BlogContent> _list = new List<BlogContent>();MySqlConnection conn = new MySqlConnection(ConnectionString);MySqlDataReader dr = null;try{conn.Open();totalItem = Convert.ToInt32(MySqlHelper.ExecuteScalar(conn, string.Format("SELECT COUNT(0) FROM BlogContent WHERE uid=@uid AND IsDelete=0 AND IsPublished=1 {0}", IsManager ? string.Empty : IsFriend ? "AND IsPublic<=1" : "AND IsPublic=0"),new MySqlParameter("@uid", userID)));if (totalItem > 0){string sql = @"SELECT Id,CateId,Title,Intro,Published,Created,ViewNums,CopNums,IsPublic,IsTop,IsPublished,Iscopied,OriginID,uid,OrignAccountId,OriginAccountName,Flowers FROM BlogContentWHERE uid=@uid AND IsDelete=0 AND IsPublished=1 {0}ORDER BY IsTop DESC,Id DESC LIMIT @Begin,@Size";dr = MySqlHelper.ExecuteReader(conn, string.Format(sql, IsManager ? string.Empty : IsFriend ? "AND IsPublic<=1" : "AND IsPublic=0"),new MySqlParameter("@uid", userID),new MySqlParameter("@Begin", (pageIndex - 1) * pageSize),new MySqlParameter("@Size", pageSize));while (dr.Read()){_list.Add(new BlogContent(){Id = dr.GetInt64(0),CateId = dr.GetInt64(1),Title = dr.GetString(2),Intro = dr.GetString(3),Published = dr.GetDateTime(4),Created = dr.GetDateTime(5),ViewNums = dr.GetInt32(6),CopNums = dr.GetInt32(7),IsPublic = dr.GetByte(8),IsTop = dr.GetBoolean(9),IsPublished = dr.GetBoolean(10),Iscopied = dr.GetBoolean(11),OriginID = dr.GetInt64(12),uid = dr.GetInt32(13),OrignAccountId = dr.GetInt32(14),OriginAccountName = dr.GetString(15),Flower = dr.GetInt32(16)});}}}catch (MySqlException e){throw e;}finally{if (null != dr) dr.Close();conn.Close();}return _list;}

 

B，数据操作接口层（IEnumerable<>）

    

        /// <summary>/// 获取文章列表/// </summary>/// <param name="userID">用户ID集合</param>/// <param name="totalItem">总数据量</param>/// <param name="pageIndex">当前页</param>/// <param name="pageSize">每页数量</param>/// <param name="IsDelete">删除状态</param>/// <returns></returns>IEnumerable<BlogContent> GetBlogContents(List<int> userIDs, ref int totalItem, int pageIndex = 1, int pageSize = 20, bool IsFriend = false, bool IsManager = false);

　　

C，控制器

     

var blogs1 = _blogManager.GetBlogContents(zone.UserID, ref totalItem, page, 10).ToList();
