快速理解WP7的Isolated Storage

这篇文章很好的介绍了Isolated Storage。取其精华作为以后参考。

Isolated Storage的结构

示例代码如下：

protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
      {         
string text;
if (IsolatedStorageSettings.ApplicationSettings.TryGetValue("text", out text))
         {            
this.textBox1.Text = text;
         }

         var fileStorage = IsolatedStorageFile.GetUserStoreForApplication();
if(fileStorage.FileExists("text.txt"))
         {
using(var fin = new StreamReader(new IsolatedStorageFileStream("text.txt", FileMode.Open, fileStorage)))
            {
this.textBox2.Text = fin.ReadToEnd();
            }            
         }
      }

private void button1_Click(object sender, RoutedEventArgs e)
      {
         IsolatedStorageSettings.ApplicationSettings["text"] = textBox1.Text;
      }

private void button2_Click(object sender, RoutedEventArgs e)
      {
         var fileStorage = IsolatedStorageFile.GetUserStoreForApplication();
using (var writer = new StreamWriter(new IsolatedStorageFileStream("text.txt", FileMode.OpenOrCreate, fileStorage)))
         {
            writer.Write(textBox2.Text);
         }
      }
