可能我没说清楚吧，我程序中就是用的sqlquery的泛型。可是存储过程的返回值取不到。

  SqlParameter[] param=new SqlParameter[]
            {
                new SqlParameter("@orderId",20)
                ,new SqlParameter("@orderLineId", System.Data.SqlDbType.Int)
                ,new SqlParameter("@Return", SqlDbType.Int)
            };
            param[1].Direction = ParameterDirection.Output;
            param[2].Direction = ParameterDirection.ReturnValue;
            string sql = "GetOrderLine @orderId,@orderLineId";
            int result;
            using (MyTestEntities db=new MyTestEntities())
            {
                //using (DbConnection conn=db.Database.Connection)
                //{
                //    conn.Open();
                //    using (DbCommand cmd=conn.CreateCommand())
                //    {
                //        cmd.CommandText = sql;
                //        cmd.Parameters.AddRange(param);
                //        cmd.CommandType = CommandType.StoredProcedure;
                //        cmd.ExecuteScalar();
                //    }
                   
                //}
             
                result = db.Database.SqlQuery<int>(sql, param).FirstOrDefault();
            }
            var result1 = param[1].Value.ToString();
            var result2 = param[2].Value.ToString();
            return Ok();

而且sq.database.sqlquery也是返回查询的结果集。sql.database.executesqlcommand才会返回受影响的行数
