我要求传递到我的视图的验证错误消息来自数据库。
我想在我的模型上使用数据注释，但验证属性中的错误消息键只能是字符串或常量。
我愿意接受其他验证解决方案，但我需要从数据库中提取错误消息。
如果错误消息不是字符串，是否还有其他有效的验证解决方案？现在我正在考虑使用 T4 生成常量文件......
I have a requirement that the validation error messages that are passed to my view come from the database.
I want to use data annotation on my model but the error message key in validation attributes can only be a string or a constant.
I'm open to other solutions for validation but I need to pull the error messages from the database.
Are there any other ellegent solutions for validation were the error message is not a string? Right now I am thinking about using T4 to generate a constants file...

我的具体问题可以通过使用 ASP.NET MVC2 元数据和模型验证提供程序来解决。
以下是让我开始的文章：

My specific problem can be solved by using the ASP.NET MVC2 Metadata and Model Validation Providers.
Here are the articles that got me started:

您可以使验证运行程序过载，以将错误消息与数据库中的错误消息交换。
You could overload the validation runner to swap out error messages with ones from a database.
