如何为具有不同属性的嵌套类定义映射？

Question

我有以下课程

class Employment{
 public string Company{get; set;}
 public string Since{get; set;}
 public string Position{get; set;}
}

class Person{
 public string FullName {get; set;}
 public Employment Employment{get; set;}
}

我希望将其转换为以下类

class PersonEntity{
 public string FullName {get; set;}
 public string EmploymentCompany{get; set;}
 public string EmploymentSince{get; set;}
 public string EmploymentPosition{get; set;}
}

我已定义了以下映射

mce.CreateMap<Person, PersonEntity>();

mce.CreateMap<Employment, PersonEntity>
.ForMember(d=>d.EmploymentCompany, o=>o.MapFrom(s=>s.Company))
.ForMember(d=>d.EmploymentSince, o=>o.MapFrom(s=>s.Since))
.ForMember(d=>d.EmploymentPosition, o=>o.MapFrom(s=>s.Position))
.ForAllOtherMembers(o=>o.Ignore())
;

当我运行时，它给我的第一个错误是d.EmploymentCompany未映射。如果我添加了Ignore（），则它在JobSince上会给出错误，因为未映射。

正确的映射方式是什么？

正确的映射类的方法如下：

 CreateMap<Person, PersonEntity>()
                .ForMember(d => d.EmploymentCompany, o => o.MapFrom(s => s.Employment.Company))
                .ForMember(d => d.EmploymentSince, o => o.MapFrom(s => s.Employment.Since))
                .ForMember(d => d.EmploymentPosition, o => o.MapFrom(s => s.Employment.Position)) ;
