silverlight 国际化的一种实现方法

大致思路如下：定义一个语言转换器并实现INotifyPropertyChanged接口，在转换器实现的时候调用资源文件，通过PropertyChangedEventHandler通知UI从而实现多语言。

    public class LanguageConverter : IValueConverter, INotifyPropertyChanged
    {
        #region IValueConverter
        /// Converter to go find a string based on the UI culture
        public object Convert(object value, Type targetType,
                              object parameter, CultureInfo culture)
        {
            if ((value == null) || !(value is string))
                return "set Binding Path/Source!";

            return StringResourceManager.GetString(
                    (string)parameter, System.Threading.Thread.CurrentThread.CurrentUICulture);
          }

        public object ConvertBack(object value, Type targetType,
            object parameter, CultureInfo culture)
        {
            throw new NotImplementedException("No reason to do this.");
        }

        #endregion IValueConverter

        #region INotifyPropertyChanged Members

        public event PropertyChangedEventHandler PropertyChanged;

        /// <summary>
        /// Change the culture for the application.
        /// </summary>
        /// <param name="culture">Full culture name</param>
        public void ChangeCulture(string culture)
        {
            System.Threading.Thread.CurrentThread.CurrentUICulture =
                new System.Globalization.CultureInfo(culture);
            System.Threading.Thread.CurrentThread.CurrentCulture =
                    System.Threading.Thread.CurrentThread.CurrentUICulture;
            DefaultResource.Culture = System.Threading.Thread.CurrentThread.CurrentUICulture;

            // notify that the culture has changed
            PropertyChangedEventHandler handler = PropertyChanged;

            if (handler != null)
                handler(this, new PropertyChangedEventArgs("AString"));
        }
　　　　public static string AString { get { return "AString"; } }

        #endregion
    }
