推荐答案

尝试使用这个类实现

     public class LocalSetting
{


   public LocalSetting()
   {

   }

   public void Write(string key,string value)
   {
       try
       {
           var localSettings = Windows.Storage.ApplicationData.Current.LocalSettings;
           localSettings.Values[key] = value;
       }
       catch(Exception)
       {
           MessageDialog msgbox = new MessageDialog("Erreur d'ecriture");
           msgbox.ShowAsync();
           return;

       }


   }

   public String Read(string key)
   {
       try
       {
       var localSettings = Windows.Storage.ApplicationData.Current.LocalSettings;
       if(localSettings.Values.Keys.Contains(key))

      return localSettings.Values[key].ToString();
       else 
      return "";



         }
       catch(Exception)
       {
           MessageDialog msgbox = new MessageDialog("Erreur de lecture");
           msgbox.ShowAsync();
           return "";

       }
   }



}
