Question

对我的问题有一点了解，我有如下四类的employee，employeedto，request和requestedto，它们具有循环引用，我为它们创建了映射配置，但是当我尝试将雇员列表映射到employeedtos时，即使我正在使用MaxDepth（1），也会得到stackoverflow异常。

public class Employee
{
    public string Name { get; set; }
    public List<Request> Requests { get; set; }
}

public class EmployeeDto
{
    public string Name { get; set; }
    public List<RequestDto> RequestsDto { get; set; }
}

public class Request
{
    public int Id { get; set; }
    public Employee CreatedBy { get; set; }
}

public class RequestDto
{
    public int Id { get; set; }
    public EmployeeDto CreatedBy { get; set; }
}

映射配置：

cfg.CreateMap<Employee, EmployeeDto>().MaxDepth(1)
    .ForMember(dest => dest.Name, opt => opt.MapFrom(src => src.Name))
    .AfterMap((src, dest, context) =>
    {
        dest.RequestsDto = context.Mapper.Map<List<RequestDto>>(src.Requests);
    });

cfg.CreateMap<EmployeeDto, Employee>().MaxDepth(1)
    .ForMember(dest => dest.Name, opt => opt.MapFrom(src => src.Name))
    .AfterMap((src, dest, context) =>
    {
        dest.Requests = context.Mapper.Map<List<Request>>(src.RequestsDto);
    });

cfg.CreateMap<Request, RequestDto>().MaxDepth(1)
    .ForMember(dest => dest.Id, opt => opt.MapFrom(src => src.Id))
    .AfterMap((src, dest, context) =>
    {
        dest.CreatedBy = context.Mapper.Map<EmployeeDto>(src.CreatedBy);
    });

cfg.CreateMap<RequestDto, Request>().MaxDepth(1)
    .ForMember(dest => dest.Id, opt => opt.MapFrom(src => src.Id))
    .AfterMap((src, dest, context) =>
    {
        dest.CreatedBy = context.Mapper.Map<Employee>(src.CreatedBy);
    });

当我尝试将员工映射到employeetos时，此行发生例外。

var mapped = _mapper.Map<List<EmployeeDto>>(employees);
