Question

I’ve developed a sample software in c# windows Appliation. How to make it a multilingual supporting software.

For Example: One of the message boxes display ” Welcome to sample application”

i installed the software in a chinees os , but it displays the message in english only.

i’m using “string table” (Resource File) for this problem.

In string table i need to create entry for each messages in english and Chinees.

its a timely process. is there any other way to do this?

Create Resources files for each language you want to give support for mentioned below.

Based on the language/currentculture of the user, read values from respective Language Resource file and display in label or MessageBox. Here’s some sample code:

public static class Translate

{

    public static string GetLanguage()

    {

        return HttpContext.Current.Request.UserLanguages[0];

    }



    public static string Message(string key)

    {

        ResourceManager resMan = null;

        if (HttpContext.Current.Cache["resMan" + Global.GetLanguage()] == null)

        {

            resMan = Language.GetResourceManager(Global.GetLanguage());

            if (resMan != null) HttpContext.Current.Cache["resMan" + Global.GetLanguage()] = resMan;

        }

        else

            resMan = (ResourceManager)HttpContext.Current.Cache["resMan" + Global.GetLanguage()];



        if (resMan == null) return key;



        string originalKey = key;

        key = Regex.Replace(key, "[ ./]", "_");



        try

        {

            string value = resMan.GetString(key);

            if (value != null) return value;

            return originalKey;

        }

        catch (MissingManifestResourceException)

        {

            try

            {

                return HttpContext.GetGlobalResourceObject("en_au", key).ToString();

            }

            catch (MissingManifestResourceException mmre)

            {

                throw new System.IO.FileNotFoundException("Could not locate the en_au.resx resource file. This is the default language pack, and needs to exist within the Resources project.", mmre);

            }

            catch (NullReferenceException)

            {

                return originalKey;

            }

        }

        catch (NullReferenceException)

        {

            return originalKey;

        }

    }

}

In asn asp.net application, you’d use it as following:

<span class="label">User:</span>

You now would put:

<span class="label"><%=Translate.Message("User") %>:</span>
