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();

}

}

}
