REST Routing in ServiceStack - servicestack

Question

I just start to learn REST and ServiceStack and there's something about Route that I just can't quite understand. For example if we take the very basic HelloWorld example from GitHub tutorial and re-write it to return collection of User objects. Here is example:
public User
{
public string Name;
public string Address;
public int Age;
}
// Hello - request object without [Route] attribute
public class Hello
{
public string Name { get; set; }
}
public class HelloResponse
{
public IEnumerable<User> Result {get;set;}
}
public class HelloService : Service
{
public object Any(Hello request)
{
return new HelloResponse { // Collection of User object };
}
}
now everything working right and no problems here. But now I want to add another routing url like: /Hello/{name}/Address
Actually this call (GET) to this url will return a single User selected by Age parameter. How I can do this ? Should I add another Service ? And if the url will be:
/Hello/{name}/{age}/Address
It seems I don't understand something.....

See this earlier answer for details about Routing in ServiceStack. The Smart Routing section in ServiceStack's New API explains further options and different precedence.
There are a few problems with your example. First ServiceStack text serializers only support public properties so you need to change your User Model to use public properties instead of fields, e.g:
public User
{
public string Name { get; set; }
public string Address { get; set; }
public int Age { get; set; }
}
Next, Interfaces on DTOs are a bad idea as there's no good reason for it. They're still supported but you can end up with undesirable results. Use a concrete collection like a List<T> which provides more utility, e.g:
public class HelloResponse
{
public List<User> Results { get; set; }
}
Also the routes should match the property names on your DTO exactly, they are case-insensitive when matching against the Request Path, but they need to map to an exact property name, e.g:
/Hello/{Name}/{Age}/Address
