Auto Mapper Null参考

问题描述

| 我有自动映射器的问题，该问题会引发Null引用异常。

Mapper.CreateMap<People,PeopleDto>()
      .ForMember(d => d.Country,opt => opt.MapFrom(o => o.Address.Country)) 

问题是，当Address为null并尝试获取地图Address.Country时     

解决方法

        

Mapper.CreateMap() .ForMember(d => d.Country,opt => opt.MapFrom(o => (o.Address != null) ? o.Address.Country : \"ADDRESS NOT SPECIFIED\"))
