ExecuteReader模型里的for循环能用foreach代替吗

Question

我尝试了一下，不知为何不可以，只输出了一个命名空间                    using (SqlDataReader reader = cmd.ExecuteReader())                     {                                                 while (reader.Read())                         {                             foreach(object item in reader)                             {                                 Console.Write(item.ToString());                             }                             Console.WriteLine();                         }                     }
