Magellan Route Registration

by Paul Stovell via Paul Stovell on 5/2/2010 12:27:40 PM

This week I have been working on a routing system for Magellan. The goal was to make it very similar to ASP.NET's style of routing:

Routes.Register("Default", 
    "{controller}/{action}/{id}",                            // Path specification
    new { controller = "Home", action = "Index", id = "" },  // Defaults
    new { id = "^[0-9]+$" }                                  // Constraints
);

Unfortunately, I hadn't counted on Silverlight's security implementation. Since anonymous types are internal, I can't use reflection to pull apart the defaults and constraints the way ASP.NET MVC does.

Which of these syntaxes do you prefer?

Routes.Register("Default", "{controller}/{action}/{id}")
    .Defaults(controller => "Home", action => "Index", id => "")
    .Constraints(id => "^[0-9]+$");

Routes.Register("Default", 
    "{controller}/{action}/{id}",
    new Defaults(controller => "Home", action => "Index", id => ""),
    new Constraints(id => "^[0-9]+$")
);

Alternatively, please suggest a better alternative :)
