模型和视图模型之间的 AutoMapper 错误：缺少类型映射配置或不支持的映射

Question

好吧，我正在尝试映射我的用户配置文件模型 to/from 用户配置文件视图模型，但它不会工作，因为它们不共享所有数据字段：

型号：

    public class UserProfile
{
    public virtual string Id { get; set; }
    public virtual string Interests { get; set; }
    public virtual string Biography { get; set; }
    public virtual string SmokingAttitude { get; set; }
    public virtual string DrinkingAttitude { get; set; }
    public virtual string Projects { get; set; }
    public virtual string Groups { get; set; }
}

视图模型：

    public class UserProfileViewModel
{
    [Display(Name = "Interests")]
    public string Interests { get; set; }

    [Display(Name = "Biography/Comments")]
    public string Biography { get; set; }

    [Display(Name = "Attitude to Smoking")]
    public string SmokingAttitude { get; set; }

    [Display(Name = "Attitude to Drinking")]
    public string DrinkingAttitude { get; set; }

    [Display(Name = "Projects working on")]
    public string Projects { get; set; }

    [Display(Name = "Groups joined")]
    public string Groups { get; set; }


    public IEnumerable<SelectListItem> AttitudeList
    {
        get
        {
            return new[]{
                new SelectListItem {Value = "not specified", Text = "not specified"},
                new SelectListItem {Value = "very negative", Text = "very negative"},
                new SelectListItem {Value = "negative", Text = "negative"}, 
                new SelectListItem {Value = "compromisable",  Text = "compromisable"},
                new SelectListItem {Value = "neutral", Text = "neutral"},
                new SelectListItem {Value = "positive", Text = "positive"},
            };
        }
    }
}

如您所见，ID 属性存储在用户配置文件模型中（作为用户 table 的键），但不在用户配置文件视图模型中。不过，用户配置文件视图模型有一个附加字段 AttitudeList 定义用于 selection/dropdown 列表操作。我认为这是自动映射器无法正常工作的原因，但我完全不知道如何解决这个问题。

有人可以帮忙吗？这个想法只是从模型 to/from 视图模型映射公共字段，同时忽略不同的字段。我希望我不必手动映射它们并编写数十行代码...

忽略那个属性。

Mapper.CreateMap<UserProfile, UserProfileViewModel>()
        .Ignore(dst => dst.AttitudeList);

Ignore mapping one property with Automapper
