我应该如何处理.NET对象中的复合键

I'm working on an MVC.NET application that uses several database tables that have composite keys. What's the best way to map these composite keys in my ORMs? My first thought was to use dictionary fields i.e. classKey AS dictionary(of string, string). This seems to work ok, but complicates the parameters of my controller methods...especially when going from the client to the controller. Then I thought use a string as the "Id" property in my objects models and create hashes out of the composite keys at the controller level to populate the Ids...not sure if I like this either. Your thoughts?

Let's assume your composite key is (string a, int b). Then you could write your action like this:

假设你的复合键是(字符串a,int b)。然后你可以像这样编写你的动作:

ActionResult Index(string a, int b) { }

or

class MyCompositeKey { string a; int b; }
ActionResult Index(MyCompositeKey id) { }
