在ASP.NET MVC3中验证表单时,是否有任何方法可以忽略某些属性(在POCO上)？

public class IgnoreAttribute : Attribute
{
    public bool Ignore { get; set; }

    public IgnoreAttribute(bool ignore = true)
    {
        Ignore = ignore;
    }
}

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

    [Ignore(true)]
    public string IgnoredProperty { get; set; }
}

public class IgnoreAttributeModelValidatorProvider : DataAnnotationsModelValidatorProvider
{
    protected override IEnumerable<ModelValidator> GetValidators(ModelMetadata metadata, ControllerContext context, IEnumerable<Attribute> attributes)
    {
        var baseValidators = base.GetValidators(metadata, context, attributes);
        var ignoreAttribute = attributes.OfType<IgnoreAttribute>().FirstOrDefault();

        if (ignoreAttribute != null && ignoreAttribute.Ignore)
        {
            return Enumerable.Empty<ModelValidator>();
        }

        return baseValidators;
    }
}

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();

    RegisterGlobalFilters(GlobalFilters.Filters);
    RegisterRoutes(RouteTable.Routes);

    ModelValidatorProviders.Providers.Add(new IgnoreAttributeModelValidatorProvider());
}
