使用映射规则手动映射对象中的对象

示例代码：

public class SourceNestedObject { public int Id { get; set; } public string Name { get; set; } }

public class SourceObject { public int Id { get; set; } public string Name { get; set; } public SourceNestedObject NestedObject { get; set; } }

public class DestinationNestedObject { public int Id { get; set; } public string Name { get; set; } }

public class DestinationObject { public int Id { get; set; } public string Name { get; set; } public DestinationNestedObject NestedObject { get; set; } }

CreateMap() .ForMember(dest => dest.NestedObject, opt => opt.MapFrom(src => new DestinationNestedObject { Id = src.NestedObject.Id, Name = src.NestedObject.Name }));
