EasyUI分页兼条件查询

//控制器
  public ActionResult GetAllUserInfo()
        {
            int pageIndex = Request["page"] == null ? 1 : int.Parse(Request["page"]);
            int pageSize = Request["rows"] == null ? 10 : int.Parse(Request["rows"]);
            int total = 0;
           var temp = userInfoService.Query(s => s.UserName != null);

            //真分页
            total = temp.Count();  
            var users = temp.OrderByDescending(s => s.UserId)
                     .Skip<UserInfo>((pageIndex - 1) * pageSize).Take<UserInfo>(pageSize);
