.net redis数据缓存（二） redis操作List集合带分页

1、编写一个简单的redishelper类库，封装ServiceStack.Redis

2、数据展示与分页

2.1 后台代码

 public class HomeController : Controller
    {
        // GET: Home
        public ActionResult Index(int page = 1)
        {
            PageMassage pagMsg = new PageMassage();
            pagMsg.thisPage = page;
            pagMsg.thisRow = 15;
            if (pagMsg.thisPage <= 0)
            {
                pagMsg.thisPage = 1;
            }
            ViewBag.thisPage = pagMsg.thisPage;
            //设置string

            using (var cliend = RedisHelper.GetClient())
            {
                //获取数据

                user = new List<UserInfoModel>();
                user = RedisHelper.Get<List<UserInfoModel>>("UserName", cliend);

                        UserInfoModel uu = new UserInfoModel();
                        uu.Id = i + 1;
                        uu.Nmae = "李" + i.ToString() + "号";
                        uu.Age = 45 + i;
                        uu.Sex = new Random().Next(0, 1) == 0 ? "女" : "男";
                        uu.Bir = DateTime.Now;
                        uu.Adddate = DateTime.Now;
                        user.Add(uu);
                    }

                    bool flag = RedisHelper.Set<List<UserInfoModel>>("UserName", user, cliend);

                }
            }

            if (pagMsg.thisSeachKey != null)
            {
                user = user.OrderBy(q => q.Id).Where(q => q.Nmae.Contains(pagMsg.thisSeachKey)).ToList();
            }
            else
            {
                user = user.OrderBy(q => q.Id).ToList();
            }
            ViewBag.User = user.ToPagedList(pagMsg.thisPage, pagMsg.thisRow);
            //ViewBag.User = user;
            return View();
        }

    }

    public class PageMassage
    {
        /// <summary>
        /// 當前頁
        /// </summary>
        public int thisPage { get; set; }
        /// <summary>
        /// 每頁顯示
        /// </summary>
        public int thisRow { get; set; }

        /// <summary>
        /// 搜索内容
        /// </summary>
        public string thisSeachKey { get; set; }

    }

2.2 前台展示

31             </tr>
32         }

36         <span style="font-size:20px;color:blue;">
37             每页 @userModel.PageSize 条记录，共 @userModel.PageCount 页，当前第 @userModel.PageNumber 页

39          @Html.PagedListPager(userModel, page => Url.Action("Index", new { page }))

3.配置文件
 <!--redis写入-->
    <add key="WriteServerList" value="192.168.1.188:6379" />
    <!--redis读取-->
    <add key="ReadServerList" value="192.168.1.188:6379" />
    <!--密码-->
