Similar to KingNestor's implementation, you can also do the followings which will ease your work:
1) Write Your Model
public class MyUser{public String UserName{get; set;}}
2) add route to global asax
routes.MapRoute(
"NameRouting",
"{name}",
new { controller = "PersonalPage", action = "Index", username="name" });
3) Roll your own custom model binder derived from IModelBinder
public class CustomBinder : IModelBinder
{
public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
var request = controllerContext.HttpContext.Request;
var username = getUserNameFromDashedString(request["username"]);
MyUser user = new MyUser(username);
return user;
}
}
4) in your action:
public ActionResult Index([ModelBinder(typeof(CustomBinder))] MyUser usr)
{
ViewData["Welcome"] = "Viewing " + usr.Username;
return View();
}
