@

简介

什么是Dikeko.ORM？

Dikeko.ORM是一个简单的.NET轻量级的ORM，目前仅支持SqlServer数据库。

安装

.NET版：https://www.nuget.org/packages/Dikeko.ORM

PM>Install-Package Dikeko.ORM

.NET CORE版：https://www.nuget.org/packages/Dikeko.ORM.Core

PM>Install-Package Dikeko.ORM.Core

源码

.NET 版：https://github.com/cnsmallant/Dikeko.ORM

.NET CORE版：https://github.com/cnsmallant/Dikeko.ORM.Core

注意

Dikeko.ORM仅支持SqlServer数据库，.NET CORE版需要手动添加实体类，或者下载源码获取T4模版。

实体类示例：
