WPF学习笔记 - .Net Framework的分离存储技术

写入：

protected override void OnClosed(EventArgs e)

{

    base.OnClosed(e);

    IsolatedStorageFile f = IsolatedStorageFile.GetUserStoreForAssembly();

    using(IsolatedStorageFileStream stream = new IsolatedStorageFileStream("myFile", FileMode.Create, f))

    using{StreamWriter writer = new StreamWriter(stream ))

    {

         foreach(TreeViewItem item in favoritesItem.Items)

            writer.WriteLine(item.Tag as string);

    }

}

读取：

protected overrider void OnInitialized(EventArgs e)

{

    base.OnInitialized(e);

    IsolatedStorageFile f = IsolatedStorageFile.GetUserStoreForAssembly();

    using(IsolatedStorageFileStream stream = new IsolatedStorageFileStream("myFile", FileMode.OpenOrCreate, f))

    using{StreamReader reader = new StreamReader(stream ))

    {

        string line = reader.Readline();

        while(line != null)

        {

             //读取后的逻辑

            line = reader.Readline();

        }

    }

}
