EF中执行存储过程

SqlParameter[] parms = new SqlParameter[5];
                SqlParameter parms0 = new SqlParameter("IsAll", int.Parse(parames.P1)); //生成一个参数并给参数赋值。
                SqlParameter parms1 = new SqlParameter("ForumId", int.Parse(parames.P2));
                SqlParameter parms2 = new SqlParameter("CustomerId", int.Parse(parames.P3));
                SqlParameter parms3 = new SqlParameter("PostId", int.Parse(parames.P4));
                SqlParameter parms4 = new SqlParameter("TopicId", int.Parse(parames.P5));
                parms[0] = parms0;
                parms[1] = parms1;
                parms[2] = parms2;
                parms[3] = parms3;
                parms[4] = parms4;
                var postdatalist = _addressRepository.SqlQuery<Post>("exec GetPostList @IsAll,@ForumId,@CustomerId,@PostId,@TopicId ", parms);
                int pageindex = string.IsNullOrEmpty(parames.P9) ? 0 : int.Parse(parames.P9);
                int pagesize = string.IsNullOrEmpty(parames.P10) ? 0 : int.Parse(parames.P10);
                PagedList<Post> pageddata = new PagedList<Post>(postdatalist.OrderBy(p => p.CreatedOnUtc).ToList(), int.Parse(parames.P9), int.Parse(parames.P10));
                result.success = "true";
                result.retcode = RetCode.successKey;
                result.data = JsonHelper.ListToJson<Post>(pageddata);
                return result;
