如何在使用AutoMapper时忽略内部嵌套对象

你好，我有类:

类用户

public class User
{
    public Int64 Id { get; set; }
    public string Name { get; set; }
    public string Email { get; set; }        
    public Profile Profile { get; set; } //EF one to one
}

类概要

    public class Profile 
{
    public Int64 Id { get; set; }
    public string Skype { get; set; }
    public string Phone { get; set; }
    public string Mobile { get; set; }
    public virtual ICollection<Address> Addresses { get; set; }
    public virtual User User { get; set; } //This is because EF Mappings
}

类用户DTO

public class UserDTO
{
    public string Name { get; set; }
    public string Email { get; set; }        
    public Profile Profile { get; set; }
}

我做了配置映射用户到UserDTO

Mapper.CreateMap<User, UserDTO>();

我需要有配置文件。用户，因为实体框架一对一的关系，但我不想要配置文件。要在映射中显示的用户。

如何忽略Profile.User?

public class UserProfileDTO
{
    public string Skype { get; set; }
    public string Phone { get; set; }
    public string Mobile { get; set; }
    public ICollection<AddressDTO> Addresses { get; set; }
}
public class UserDTO
{
    public string Name { get; set; }
    public string Email { get; set; }
    public UserProfileDTO Profile { get; set; }
}
Mapper.CreateMap<User, UserDTO>();
Mapper.CreateMap<Profile, UserProfileDTO>();
