以上是好友分类的一个底层BLL的相关代码：（他将一些逻辑方面的操作放到此处进行处理）

SpaceFriendController控制器里有对自己定义BLL的调用：

      [HttpGet]
        [SupportFilter(FCode = "PersonalSpace_SpaceFriend_List")]//判断页面是否有权限，FCode 调用枚举，没有的自己补，格式为：Areas_Controller_Action,例如：Heart_AgrBaseArea_Add
        public ActionResult List(string cid, string keyword, int page = 1, int pageSize = 20) //, string keyword
        {
            IsAuthorityButton("PersonalSpace_SpaceFriend_List");
            IDictionary<string, object> dic = new Dictionary<string, object>();


            //var pageList = list.Skip((page - 1) * pageSize).Take(pageSize).ToList();
            //var pageList2 = new PagedList<UserFavorite>(pageList, page, pageSize, pageList.Count());

            var result = bll.GetSelSpaceFriends(CurrentUser.FId, cid, keyword).AsQueryable<SpaceFriend>().ToPagedList(page, 10);//, keyword
          //  ViewBag.did = did;
            using (SpaceTeamBLL teambll = new SpaceTeamBLL())
            {
                dic.Add("list", result);
                using (SpaceTeamBLL teambl = new SpaceTeamBLL())
                {
                    IQueryable<SpaceTeam> team = teambll.FindALL().Where(x => x.FUserId == CurrentUser.FId);
                    dic.Add("spaceteam", team);
                }
                return PartialView(dic);// View(dic);
            }
        }

前台页面传参操作：（FSoSo.cshtml）

@model IList<SpaceTeam>
@{
    ViewBag.Title = "分类查询+搜索视图";
    string typeTopic = ViewBag.type;
   // string did = ViewBag.did;
    if (string.IsNullOrEmpty(typeTopic))
    {
        typeTopic = "1";
    }
    int type = int.Parse(typeTopic);
    string TopPicId = ViewBag.TopPicId;
    string RelativeUrl = ViewBag.RelativeUrl;
    string to = "";
    if (!string.IsNullOrWhiteSpace(Request["cid"]))
    {
        to = Request["cid"];
    }
    string toYn = "";
    if (!string.IsNullOrWhiteSpace(Request["yn"]))
    {
        toYn = Request["yn"];
    }
}
