Answer 1

You can't because the url in the RouteConfig has a specific format:
{controller}/{action}/{id}
To get the url you want, you may create public ActionResult Blog()
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "NoScript",
url : "noscript",
defaults : new { controller = "Home", action = "EnableJavaScript"}
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",//the specific format
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}

Assuming you have a UserController with the following methods
// match http://..../arrivaler
public ActionResult Index(string username)
{
// displays the home page for a user
}
// match http://..../arrivaler/Photos
public ActionResult Photos(string username)
{
// displays a users photos
}
Route.config.cs
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "User",
url: "{username}",
defaults: new { controller = "User", action = "Index" },
constraints: new { username = new UserNameConstraint() }
);
routes.MapRoute(
name: "UserPhotos",
url: "{username}/Photos",
defaults: new { controller = "User", action = "Photos" },
constraints: new { username = new UserNameConstraint() }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Test", action = "Index", id = UrlParameter.Optional }
);
}
public class UserNameConstraint : IRouteConstraint
{
public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection)
{
List<string> users = new List<string>() { "Bryan", "Stephen" };
// Get the username from the url
var username = values["username"].ToString().ToLower();
// Check for a match (assumes case insensitive)
return users.Any(x => x.ToLower() == username);
}
}
}
If the url is .../Arrivaler, it will match the User route and you will execute the Index() method in UserController (and the value of username will be "Arrivaler")
If the url is .../Arrivaler/Photos, it will match the UserPhotos route and you will execute the Photos() method in UserController (and the value of username will be "Arrivaler")
Note that the the sample code above hard codes the users, but in reality you will call a service that returns a collection containing the valid user names. To avoid hitting the database each request, you should consider using MemoryCache to cache the collection. The code would first check if it exists, and if not populate it, then check if the collection contains the username. You would also need to ensure that the cache was invalidated if a new user was added.
