介绍一个轻量级的ORM 二

上一篇文章简单的介绍了这个ORM的很基本的用法。

似乎看不出这个ORM有什么特别的地方，是的，这个ORM并不太特别。我认为他简单易用是他的一个特点。

接上一篇

同过Sql语句填充实体

可能有时候有非常复杂的条件用来过滤记录

this.Trans = new StreamContext("NIX");
List<ZULABELMEntity> dd = this.Trans.Querys<ZULABELMEntity>(Sql语句);

 

在性能方面个人感觉似乎也免强过得去，因为没有跟那些太牛的ORM做过比较，只是简单的跟Dapper做了测试比较，比较的结果如文章结尾所示。

测试程序我也不是很清楚是否公正。

测试代码如下。

    using Dapper;
    using Dot.StreamObject;
    using Muki.Entity;
