C#中的本地化属性参数 [英] Localized Attribute parameters in C#

问题描述

在C#中，属性参数必须是常量表达式，typeof或数组创建表达式.

In C#, attribute parameters require to be a constant expression, typeof or array creation expression.

各种库(例如城堡验证器)都允许指定将看起来像本地化错误消息的内容传递给属性构造函数:

Various libraries, like for example Castle validator, allow specifying passing what seems like localized error messages to attribute constructor:

//this works
[ValidateNonEmpty("Can not be empty")]

//this does not compile
[ValidateNonEmpty(Resources.NonEmptyValidationMessage)]

有什么办法可以解决这个问题并使这些论点本地化吗?

Is there any way how to approach this problem and localize these arguments?

如果使用Castle Validator时没有解决方法，是否有类似于Castle Validator的验证库可以本地化验证消息?

In case there is no workaround for this when using Castle Validator, is there a validation library similar to Castle Validator that allows localization of validation messages?

我发现数据注释验证库如何解决此问题.非常优雅的解决方案: http://haacked.com/archive/2009/12/07/localizing-aspnetmvc-validation.aspx

I found how Data Annotations validation library approaches this problem. Very elegant solution: http://haacked.com/archive/2009/12/07/localizing-aspnetmvc-validation.aspx

推荐答案

开箱即用:

    [ValidateNonEmpty(
        FriendlyNameKey = "CorrectlyLocalized.Description",
        ErrorMessageKey = "CorrectlyLocalized.DescriptionValidateNonEmpty",
        ResourceType = typeof (Messages)
        )]
    public string Description { get; set; }
