asp.net-mvc – 如何使用Autotyper和Betty方法将DataAnnotation

我需要澄清如何实现Betty的代码解决方案,以便使用AutoMapper将数据注释元数据传输到ViewModel(参见 here).或者,如果你有更好的方法,请分享.也许对于熟悉AutoMapper的人来说,实现贝蒂的答案是显而易见的,但我是新手.

这是一个简单的例子,我将如何添加到此代码中以使Betty的解决方案工作：

// Data model Entity
public class User1
{

    [Required]
    public int Id { get; set; }

    [Required]
    [StringLength(60)]
    public string FirstName { get; set; }

    [Required]
    [StringLength(60)]
    public string LastName { get; set; }

    [Required]
    [DataType(DataType.Password)]
    [StringLength(40)]
    public string Password { get; set; }

}

// ViewModel
public class UserViewModel
{

    public string FirstName { get; set; }

    public string LastName { get; set; }

    public string Password { get; set; }

}

当前的AutoMapper实现：

// Called once somewhere
Mapper.CreateMap<User1,UserViewModel>(MemberList.Destination);

// Called in controller method,or wherever
User user = new User() { FirstName = "Tony",LastName = "Baloney",Password = "secret",Id = 10 };

UserViewModel userVM = Mapper.Map<User,UserViewModel>(user);

// NOW WHAT???

我在Application_Start中的global.asax中尝试过这个：

var configProvider = Mapper.Configuration as IConfigurationProvider;
ModelMetadataProviders.Current = new MetadataProvider(configProvider);
ModelValidatorProviders.Providers.Clear(); // everything's broke when this is not done
ModelValidatorProviders.Providers.Add(new ValidatorProvider(configProvider));

另外,我不得不修改Betty的GetMappedAttributes：

propertyMap.DestinationProperty.GetCustomAttributes：
propertyMap.DestinationProperty.MemberInfo.GetCustomAttributes

(或者代替MemberInfo,是MemberType吗？)为此甚至构建.

但似乎没有任何效果.

ModelMetadataProviders.Current = new MetadataProvider(
        AutoMapper.Mapper.Engine.ConfigurationProvider);

ModelValidatorProviders.Providers.Add(new ValidatorProvider(
        AutoMapper.Mapper.Engine.ConfigurationProvider);

ModelMetadataProviders.Current = new MetadataProvider(
        (AutoMapper.IConfigurationProvider)AutoMapper.Mapper.Configuration);

ModelValidatorProviders.Providers.Add(new ValidatorProvider(
        (AutoMapper.IConfigurationProvider)AutoMapper.Mapper.Configuration));
