部分类中的DataAnnotations问题 [英] Problem with DataAnnotations in partial class

问题描述

所以在我的mvc项目的Project.Repository中，

So in my mvc project's Project.Repository I have

[MetadataType(typeof(FalalaMetadata))]
public partial class Falala
{
    public string Name { get; set; }

    public string Age { get; set; }

    internal sealed class FalalaMetadata
    {
        [Required(ErrorMessage="Falala requires name.")]
        public string Name { get; set; }

        [Required(ErrorMessage = "Falala requires age.")]
        public string Age { get; set; }
    }
}

我在我的Project.Web.AccountControllers中使用Falala作为模型，并使用一种获取违规的方法. 拥有

I use Falala as a model in my Project.Web.AccountControllers, and use a method to get violations. Validating worked when I had

public class Falala
{
    [Required]
    public string Name { get; set; }

    [Required(ErrorMessage="error")]
    public string Age { get; set; }
}

，但在使用上面的分部类后不会出现. 我真的需要使用局部类.我在这里做什么错了?

but not after using the partial class from above. I really need to use a partial class. What am I doing wrong here?

谢谢！

推荐答案

嵌套类中的Internal是否可能是原因?

Could Internal on the nested class be the reason...?

我遇到了一个类似的问题，这似乎归结为不公开嵌套元数据类中的各个字段-想知道是否使整个类的内部出现相同的问题吗?

I had a similiar problem and it seemed to all boiled down to not making the individual fields in the nested metadata class public - wonder if making the whole class internal causes the same problem?
