写

   private void Button_Click_1(object sender, RoutedEventArgs e)
         {
             IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication();
             using (Stream stream=isf.CreateFile("Weather.txt"))
             {
                 using (StreamWriter writer=new StreamWriter(stream))
                 {
                     writer.WriteLine(time.Text);
                     writer.WriteLine(time1.Text);
                     writer.WriteLine(time2.Text);
                     writer.WriteLine(time3.Text);
                 }
             }
         }

         {
             IsolatedStorageFile isf = IsolatedStorageFile.GetUserStoreForApplication();
             if (isf.FileExists("Weather.txt"))
             {
                 using (Stream stream = isf.OpenFile("Weather.txt", FileMode.Open))
                 {
                     using (StreamReader reader = new StreamReader(stream))
                     {
                         string line = reader.ReadToEnd();

                 }
