asp.net-web-api – Web API中的多态：单端点可能？

[Serializable]
public abstract class Command{
    public int CommandId{get; set;}
}
[Serializable]
public class RegisterNewPersonCommand:Command{
   public string Name{get; set;}
}
//etc... various Command subclasses. Similar thing for Responses.

//now have a single endpoint to Handle Commands
public class CommandsController : ApiController{
   public Response HandleCommand(Command command){
      //handle Command based on which subclass it is
      //return appropriate Response subclass
   }
}

到目前为止,似乎序列化系统似乎不能处理这种情况,但希望有人能找到一种方法:)
