普通的模型映射 现在有两个类，实体类Student和返回展示的 View类StudentView 两个实体类字段还基本可以，不是很多，假如字段非常非常多，还需要手动去赋值的话，简直太痛苦了。 想了想这才是一个方法，一般的系统都会少则几十，多则上百个这样的方法，这还不算，大家肯定遇到过一个情况，如果有一天要在页面多显示一个字段，噗！不是吧，首先要存在数据库，然后在该实体类就应该多一个，然后再在每一个赋值的地方增加一个，而且也没有更好的办法不是，一不小心就少了一个，然后被产品测试说咱们不细心，心塞哟，别慌！神器来了，一招搞定。 先来引入DTO讲解 我们已经知道了ORM（Object Relational Mapping）映射，是一种对象关系的映射，对象-关系映射(ORM)系统一般以中间件的形式存在，主要实现程序对象到关系数据库数据的映射。 而Automapper是一种实体转换关系的模型，AutoMapper是一个.NET的对象映射工具。主要作用是进行领域对象与模型（DTO）之间的转换、数据库查询结果映射至实体对象。 引入AutoMapper的包 在Services层中引用Nuget包，AutoMapper 和 AutoMapper.Extensions.Microsoft.DependencyInjection AutoMapper.Extensions.Microsoft

I had the idea of doing so by reading Matt's blog post where he says: The really key part is the AutoMapper configuration profile. You can group configurations with profiles. Maybe in one profile you format dates in one way, in another profile you format dates in another way. I’m just using one profile here. So I created a profile for one case: public class
