Windows8 - Using localised string in C#

I have got problem with localizing my app. I have got file Resources.resw with string "noResults.Text" in it (it ends with .Text because I use it in xaml for textblock (x:Uid) ) Problem is that I want to use the same string in code behind (C#) How I can access it? I have tried something like this :

resourceLoader.GetString("noResults");
resourceLoader.GetString("noResults.Text");

But none of this work

Thanks in advance :)
