C# – How to use ResourceManager in a “website” mode

asp.netclocalizationweb

I am trying here to do a manual translation for the application I am working with. (There is already a working LocalizationModule but it's working dodgy, so I can't use <asp:Localize /> tags.

Normally with ResourceManager you are supposed to be using it as Namespace.Folder.Resourcename (in an application). Currently I am translating an existing asp.net "website" (not web application so no namespace here….).

The resources are located into a folder name "Locales/resources" which contains "fr-ca.resx" and "en-us.resx".

So I used a code with something like this : 

public static string T(string search)
 {
  System.Resources.ResourceManager resMan = new System.Resources.ResourceManager( "Locales", System.Reflection.Assembly.GetExecutingAssembly(), null );

  var text = resMan.GetString(search, System.Threading.Thread.CurrentThread.CurrentCulture);

  if (text == null)
   return "null";
  else if (text == string.Empty)
   return "empty";
  else
   return text;
 }

and inside the page I have something like this <%= Locale.T("T_HOME") %>

When I refresh I have this :

Could not find any resources
appropriate for the specified culture
or the neutral culture. Make sure
"Locales.resources" was correctly
embedded or linked into assembly
"App_Code.9yopn1f7" at compile time,
or that all the satellite assemblies
required are loadable and fully
signed. Description: An unhandled
exception occurred during the
execution of the current web request.
Please review the stack trace for more
information about the error and where
it originated in the code.

I even tried to load the resource with Locales.fr-ca or only fr-ca nothing quite work here.

Marvin Smit's solution is great if you do not have access to the HTTPContext

const string ASSEMBLY_NAME = "App_GlobalResources";
const string RESOURCE_NAME = "Resources.MetaTagResource";
const string RESOURCE_MANAGER = "ResourceManager";

Assembly assembly = Assembly.Load(ASSEMBLY_NAME);
Type type = assembly.GetType(RESOURCE_NAME);
PropertyInfo propertyInfo = type.GetProperty(RESOURCE_MANAGER);
ResourceManager resourceManager = propertyInfo.GetValue(null, new object[] { }) as ResourceManager;
resourceManager.GetResourceSet(CultureInfo.InvariantCulture, true, true);

But if you have access to the HTTPContext just use HttpContext.GetGlobalResourceObject

string title = HttpContext.GetGlobalResourceObject("MetaTagResource", "Title").ToString();
string keywords = HttpContext.GetGlobalResourceObject("MetaTagResource", "keywords").ToString();
string description = HttpContext.GetGlobalResourceObject("MetaTagResource", "Description").ToString();
