为ASP.NETMVC2中的非属性化模型验证提供本地化错误消息?

DataAnnotations 属性以及ASP.Net MVC 2来为my ViewModels提供模型验证:

public class ExamplePersonViewModel {
    [Required(ErrorMessageResourceName = "Required", ErrorMessageResourceType = typeof(Resources.Validation))]
    [StringLength(128, ErrorMessageResourceName = "StringLength", ErrorMessageResourceType = typeof(Resources.Validation))]
    [DataType(DataType.Text)]
    public string Name { get; set; }

    [Required(ErrorMessageResourceName = "Required", ErrorMessageResourceType = typeof(Resources.Validation))]
    [DataType(DataType.Text)]
    public int Age { get; set; }
}

这似乎像预期的那样工作(尽管它非常冗长)。我遇到的问题是,正在执行的幕后模型验证与任何特定属性都没有关联。上述模型中的一个例子是 Age 财产需要成为 int . 如果尝试在窗体上输入非整数值,将出现以下错误(非本地化)消息:

字段年龄必须是数字。

如何本地化这些非属性验证消息?

了解可覆盖消息的完整列表应该很有趣。。。

帖子内容如下:

在App\u GlobalResources中创建一个全局资源类,并将DefaultModelBinder.ResourceClassKey设置为此类的名称(例如,如果您设置了“Messages.resx”,则将ResourceClassKey设置为“Messages”)。

在MVC 2中有两个字符串可以重写:

“PropertyValueRequired”的字符串值在用户没有为不可为空的字段(例如,整数字段)输入任何数据时使用。默认消息是:“需要一个值。”

在第二种情况下需要注意的是,如果您的验证器提供者列表中有DataAnnotationsModelValidatorProvider(默认情况下是这样),那么您将永远不会看到第二条消息。此提供程序将看到非可选字段,并向其添加隐含的[Required]属性,以便其消息与具有显式[Required]属性的其他字段保持一致,并确保您获得客户端对必填字段的验证。

[Required(ErrorMessageResourceName = "Required", ErrorMessageResourceType = typeof(Resources.Validation))]
[Range(0, int.MaxValue, ErrorMessageResourceName = "ValidateAge", ErrorMessageResourceType = typeof(Resources.Validation))]
[DataType(DataType.Text)]
public string Age { get; set; }

因此,double和Float不使用Integer,而是使用带有Range属性的字符串,并用它指定自定义的本地化错误消息。
