Multilanguage in WPF [closed]

Answer 1

Follow these steps:

1) Place all String fragments in a separate resource file.

Example: StringResources.xaml:

    
    All Vehicles

2) Make copies for each language and add them (translated) to the merged dictionaries. Don't forget to add the country's ISO code to make things easier.

Example App.xaml:

The last resource file with strings will be used to replace text parts in code.

3a) Use the text parts from the String table:

Example Window1.xaml:

3b) Load the resource from code (Only use this code if you don't want to set via XAML):

void PageLoad()
{
  string str = FindResource("All_Vehicles").ToString();
}

4) Switch to new culture at start of application:

Codesnippet from App.xaml.cs:

public static void SelectCulture(string culture)    
{      
    if (String.IsNullOrEmpty(culture))
        return;

    //Copy all MergedDictionarys into a auxiliar list.
    var dictionaryList = Application.Current.Resources.MergedDictionaries.ToList();

    //Search for the specified culture.     
    string requestedCulture = string.Format("StringResources.{0}.xaml", culture);
    var resourceDictionary = dictionaryList.
        FirstOrDefault(d => d.Source.OriginalString == requestedCulture);

    if (resourceDictionary == null)
    {
        //If not found, select our default language.             
        requestedCulture = "StringResources.xaml";
        resourceDictionary = dictionaryList.
            FirstOrDefault(d => d.Source.OriginalString == requestedCulture);
    }

    //If we have the requested resource, remove it from the list and place at the end.     
    //Then this language will be our string table to use.      
    if (resourceDictionary != null)
    {
        Application.Current.Resources.MergedDictionaries.Remove(resourceDictionary);
        Application.Current.Resources.MergedDictionaries.Add(resourceDictionary);
    }

    //Inform the threads of the new culture.     
    Thread.CurrentThread.CurrentCulture = new CultureInfo(culture);
    Thread.CurrentThread.CurrentUICulture = new CultureInfo(culture);

}
