我已经看到很多这样的错误发生的例子,因为各种各样的原因我已经看到了我能看到的所有原因,但我仍然得到错误,所以我想知道是否有人可以提供一些关于这个的信息错误实际上意味着,所以我可以尝试找到原因.这是一些代码:
控制器: [HttpPost] public ActionResult Edit(ProfileViewModel model) { if (ModelState.IsValid) { var person = new UserAttribute(); person = Mapper.Map<ProfileViewModel,UserAttribute>(model); db.UserAttribute.Add(person); db.SaveChanges(); } 查看模型 public class ProfileViewModel { [Display(Name = "First Name")] [StringLength(20)] [Required] public string FirstName { get; set; } [Display(Name = "Last Name")] [StringLength(30)] [Required] public string LastName { get; set; } [Display(Name = "Gender")] [Required] public string Gender { get; set; } [Display(Name = "Date of Birth")] [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}",ApplyFormatInEditMode = true)] public DateTime DOB { get; set; } [Display(Name = "Hair Color")] public string HairColor { get; set; } [Display(Name = "Eye Color")] public string EyeColor { get; set; } [Display(Name = "Body Type")] public string Weight { get; set; } [Display(Name = "Height")] public string HeightFeet { get; set; } public string HeightInches { get; set; } public int UserId { get; set; } public IEnumerable<SelectListItem> WeightList { get; set; } public IEnumerable<SelectListItem> EyeColorList { get; set; } public IEnumerable<SelectListItem> HairColorList { get; set; } public IEnumerable<SelectListItem> HeightFeetList { get; set; } public IEnumerable<SelectListItem> HeightInchesList { get; set; } public IEnumerable<SelectListItem> GenderList { get; set; } } UserAttribute模型: public int ProfileId { get; set; } public string FirstName { get; set; } public string LastName { get; set; } public string Gender { get; set; } public System.DateTime DOB { get; set; } public string HairColor { get; set; } public string EyeColor { get; set; } public string HeightFeet { get; set; } public string Weight { get; set; } public int UserId { get; set; } public string HeightInches { get; set; } 映射配置: public class AutoMapperConfiguration { public static void Configure() { Mapper.Initialize(x => x.AddProfile<ViewToDomainMapProfile>()); Mapper.Initialize(x => x.AddProfile<DomainToViewMapProfile>()); } } public class ViewToDomainMapProfile : Profile { public override string ProfileName { get { return "ViewToDomainMapProfile"; } } protected override void Configure() { Mapper.CreateMap<ProfileViewModel,UserAttribute>() .ForSourceMember(x => x.GenderList,y => y.Ignore()) .ForSourceMember(x => x.HairColorList,y => y.Ignore()) .ForSourceMember(x => x.EyeColorList,y => y.Ignore()) .ForSourceMember(x => x.WeightList,y => y.Ignore()) .ForSourceMember(x => x.HeightFeetList,y => y.Ignore()) .ForSourceMember(x => x.HeightInchesList,y => y.Ignore()); } } 并在全局asax中调用配置: AutoMapperConfiguration.Configure(); 解决方法
使用Mapper.AssertConfigurationIsValid();产生以下异常:
AutoMapper.AutoMapperConfigurationException : Unmapped members were found. Review the types and members below. Add a custom mapping expression,ignore,add a custom resolver,or modify the source/destination type ============================================================================================== ProfileViewModel -> UserAttribute (Destination member list) ---------------------------------------------------------------------------------------------- ProfileId 因此,您需要为ProfileId添加映射. 总的来说,使用Mapper.AssertConfigurationIsValid()是一个好习惯.要么在单元测试中(你拥有它们,对吗?),还是在映射器配置之后.它将显示此类错误配置的详细信息.
