在ASP.Net MVC 2中为非属性模型验证提供本地化错误消息？

Question

我正在使用DataAnnotations属性和ASP.Net MVC 2为我的ViewModel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; }
}

这似乎按预期工作(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无关.上述模型中的一个例子是该Age属性需要是一个int.如果您尝试在表单上输入非整数值,则会出现以下(非本地化)消息时出错:

字段Age必须是数字.

如何对这些非属性验证消息进行本地化？

是否有可用的这些消息的完整列表,以便我可以确保它们都已本地化？

该解决方案适合我.

知道可覆盖的消息的完整列表应该很有趣......

UPDATE

这里的帖子内容:

在App_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,如果您创建了"Messages.resx",则将ResourceClassKey设置为"Messages").

您可以在MVC 2中覆盖两个字符串:

• 当用户输入的数据与数据类型不兼容时(例如,为整数字段键入"abc"),将使用"PropertyValueInvalid"的字符串值.默认消息是:"值"{0}"对{1}无效."
• 当用户未输入不可为空的字段的任何数据时(例如,整数字段),将使用"PropertyValueRequired"的字符串值.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程序列表(默认情况下)中有DataAnnotationsModelValidatorProvider,那么您将永远不会看到第二条消息.此提供程序查看非可选字段并向其添加隐含[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,并确保您获得所需字段的客户端验证.
