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);
                }
            }
        }

读

 private void Button_Click_2(object sender, RoutedEventArgs e)
        {
            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();

                    }
                }
            }
        }
