How to detect the Language set in the Windows phone - windows-phone-7

Question

I need to detect the language of the phone so that I can display the message accordingly. If it is english , then display english. Say, I target a few countries such as China,japan, Korea. How do I do it? here my incomplete code to show what I mean:
tring StrLanSetOnClient;
string strLanEng= "english Msg";
string strLanChn=" Msg in chinese character";
string strLanJpn= "Msg in Japanese character";
string strLanKor= "Msg in Korean character" ;
strLanSetOnClient = CultureInfo..........
If( strLanSetOnClient == "English")
{
txtBlkLan.Text = strLanEng;
}
elseif ( strLanSetOnClient == "Chinese")
{
txtBlkLan.Text = strLanChn
}
....
Thanks
--- Updated Questions:
1) Where should I detect the language? In App.xaml?
2) How all pages can refer to this global variable name?
3) Which is the best practise to detect ? use CultureInfo or thread.currentThread
Thanks

This is the vanila csproj file of my Wp7 App. There is no SupportCulture tags in it. So, I have to add this tag in it right when I open it with notepad? When I downloaded your sample app, I open the csproj file with notepad, i dont see this tag either? Thanks

Answer 1

The way you're trying to do localization is to get very complicated, have lots of duplication and be difficult to change in the future.
There is a built in way of supporting multiple languages/cultures/etc. See http://msdn.microsoft.com/en-us/library/ff637522(v=vs.92).aspx

Answer 2

I wrote a blog on this very subject just the other day. It describes how to localize from start to finish, and it is located at www.hopnet.mobi, click Blogs.
Once you get the hang of it, localization really isn't difficult at all. I've localized one app, and I'm waiting on a friend to validate my translations. While she's doing that, I'm localizing the other apps. More languages means wider distribution, which means more money. You're doing the right thing!

Use CurrentCulture which is in your System.Globalization namespace. It has properties like Name, EnglishName, DisplayName and NativeName so you pick which one suits you most.
EDIT: Detecting the language will depend on whether you want to allow users to change the language or not. If not then detect it in App.xaml.cs and store the information in an IsolatedStorage object so that you can share it among different pages. This way you can avoid detecting the language settings later and just rely on the saved settings. As for the best practice I stick to CultureInfo. I never tried going directly through Thread.CurrentThread.
