自动映射，如何使字段不映射

Question

源类有2个属性，目标类3属性，映射，我认为在目标类中有1个属性不变，我使用NotMapped，但没有成功，但NotMapped不是我想要的方式，你是什么办？

class AAA
{
    public string Name { set; get; }
    public string Id { set; get; }
    public string Remark { set; get; }
}

class AAAViewModel
{
    public string Name { set; get; }
    public string Id { set; get; }
}

protected override MapperConfiguration Configuration => new MapperConfiguration(cfg=>
{          
    cfg.CreateMap<AAA, AAAViewModel>(MemberList.Destination);
    cfg.CreateMap<AAAViewModel, AAA>(MemberList.Source);
});

[Fact]
public void test()
{
    AAA a = new AAA() { Id = "1", Name = "name1", Remark = "remark1" };
    var avm = Mapper.Map<AAAViewModel>(a);
    AAA b = new AAA() { Remark = "remakrb" };
    b = Mapper.Map<AAA>(avm);
    Assert.Equal(avm.Id, "1");
}

该属性称为IgnoreMap。
