C#AutoMapper使⽤⽅法总结⽬录1 ⼊门例⼦2 注册2.1 Profile3 配置3.1 命名约定3.2 配置可见性3.3 全局属性/字段过滤3.4 识别前缀和后缀3.5 替换字符4 调⽤构造函数5 数组和列表映射5.1 处理空集合5.2 集合中的多态6 ⽅法到属性映射7 ⾃定义映射8 扁平化映射9 嵌套映射本⽂基于 AutoMapper 9.0.0AutoMapper 是⼀个对象-对象映射器，可以将⼀个对象映射到另⼀个对象。

1 ⼊门例⼦public class Foo{public int ID { get; set; }public string Name { get; set; }}public class FooDto{public int ID { get; set; }public string Name { get; set; }}public void Map(){var config = new MapperConfiguration(cfg => cfg.CreateMap<Foo, FooDto>());var mapper = config.CreateMapper();Foo foo = new Foo { ID = 1, Name = "Tom" };FooDto dto = mapper.Map<FooDto>(foo);}2 注册在使⽤ Map⽅法之前，⾸先要告诉 AutoMapper 什么类可以映射到什么类。

var config = new MapperConfiguration(cfg => cfg.CreateMap<Foo, FooDto>());每个 AppDomain 只能进⾏⼀次配置。

这意味着放置配置代码的最佳位置是在应⽤程序启动中，例如 应⽤程序的Global.asax ⽂件。
