Where we can add resjson files in a Metro Application

In one of my latest post I wrote a short introduction about how we can support localization in a Metro Application for Windows 8. The current framework for Metro Application makes a great job. Today I want to discuss about resjson files.
This new extension was introduce with Metro Applications and help us to store all the strings that are localized in a very simple format (key, value) using json. In this case json is better than XML (when json is not better).
By default, when we create a Metro Application, a folder named strings is created in the root of our project. Under this folder we can create us many folders we want with a name convention [cultureName]-[regionName].

string
    en-US
        Resources.resjson
        Error. resjson
        payPage. resjson
    en
        Resources. resjson
        Error. resjson
        payPage. resjson
    fe-BE
        Resources. resjson
        Error. resjson
        payPage. resjson

I have the following question for you: How many strings folders can we have in an application? Does the resjson files need to be under the strings directory?
Basically, the strings folder is only a convention; we can have the resjson files under any directory structure. To be able to load the content from these files, the framework needs two important things:
Each resjson file need to have the “Content type” property set to “Resource”. This property can be accessed from the “Properties” tab of Visual Studio.
Each resjson file need to be under a folder that specifies the culture and/or region with the following format

 [cultureName]-[regionName]

If we respect these conventions, the framework will be able to load all this resources without any problem. Because of this we can end with a custom folder structure like this:

myProject
    payment   
        pages
            payPage
                payPage.html
                payPage.css
                payPage.js
            …
        …
        resources
            en-US
                pages.resjson
                errors.resjson

What we need to remember: We can have resjson file under any directory in our project. The only thing that we need to have is the parent directory of the resjson file in the custom format to specify the culture and/or region.

How to load a resouce dynamic

Mai mult ca sigur cu toti am folosit fisiere cu resurse (*.resx). Folosirea lor nu implica nici o problema, totul este destul de simplu, dar uneori apare nevoie sa accesam o resursa in mod dinamic.
De exemplu daca avem fisierul de resurse "CarResources.resx" si vrem sa accesam resursa 'Power' avem nevoie de urmatorul cod:

string powerLabel = CarResources.Power;

Dar apare urmatoarea problema, daca resursa de care avem nevoie o putem determina doar la runtime?
O solutie ar fi sa folosim ResourcesManager, care ne permite sa incarcam o anumita resursa in mod dinamic. Exemplul de mai sus ar trebuii rescris in felul urmator:

var carResource = new ResourceManager("CarResource",Assembly.GetExecutingAssembly());
var powerLabel = carResource.GetString("Power");

Trebuie avut grija din ce assembly incarcati resursa.
