转：Entity FrameWork利用Database.SqlQuery<T>执行存储过程并返回参数

   public IEnumerable<Statistic> GetStatistics(IEnumerable<Guid> itemIds)
        {
            var ctx = new DBContext();

            return ctx.Database.SqlQuery<Statistic>("[dbo].[ItemStatisticsSelect] @Items, @IsPostModeration",
                new SqlParameter("Items", string.Join("|", itemIds)),
                new SqlParameter("IsPostModeration", true));
        }

/// <summary>  
        /// 执行原始SQL命令  
        /// </summary>  
        /// <param name="commandText">SQL命令</param>  
        /// <param name="parameters">参数</param>  
        /// <returns>影响的记录数</returns>  
        public Object[] ExecuteSqlNonQuery<T>(string commandText, params Object[] parameters)
        {
            using (DBEntities context = new DBEntities())
            {
                var results = context.Database.SqlQuery<T>(commandText, parameters);
                results.Single();
                return parameters;
            }
        }

1） EF可以执行存储过程

2）EF可以返回非DB实体
