.NET中的验证框架，可以在字段之间进行编辑(Validation Framework in .NET that can do edits between fields)

 根据我的经验，.NET中的许多验证框架允许您一次验证一个字段，例如确保字段是邮政编码或电子邮件地址。 我通常将这些内部编辑称为。 
 
 在我的项目中，我们经常需要进行场间编辑。 例如，如果您有这样的类： 
 
public class Range
{
    public int Min { get; set; }
    public int Max { get; set; }
}
 
 您可能希望确保Max大于Min。 您可能还想对外部对象进行一些验证。 例如，鉴于你有一个这样的类： 
 
public class Person
{
    public string PostalCode { get; set; }
}
 
 无论出于何种原因，您希望确保邮政编码存在于数据库或提供给您的文件中。 我有更复杂的例子，比如用户提供数据字典，你想要针对该数据字典验证你的对象。 
 
 我的问题是：我们可以使用任何现有的验证框架（TNValidate，NHibernate Validator）用于.NET，还是我们需要使用规则引擎或者什么？ 现实世界中的人们如何处理这种情况？ :-) 

From my experience many validation frameworks in .NET allow you to validate a single field at a time for doing things like ensuring a field is a postal code or email address for instance. I usually call these within-field edits.
 
In my project we often have to do between-field-edits though. For instance, if you have a class like this:
 
public class Range
{
    public int Min { get; set; }
    public int Max { get; set; }
}
 
you might want to ensure that Max is greater than Min. You might also want to do some validation against an external object. For instance given you have a class like this:
 
public class Person
{
    public string PostalCode { get; set; }
}
 
and for whatever reason you want to ensure that Postal Code exists in a database or a file provided to you. I have more complex examples like where a user provides a data dictionary and you want to validate your object against that data dictionary.
 
My question is: can we use any of the existing validation frameworks (TNValidate, NHibernate Validator) for .NET or do we need to use a rules engine or what?? How do you people in the real world deal with this situation? :-)
