Windows Phone的本地存储——IsolatedStorageFile

本篇我们来了解如何通过IsolatedStorageFile来实现信息的本地存储。使用IsolatedStorageFile和使用System.IO.File和System.IO.Directory进行文件访问非常类似，再此仅仅列出对于文本文件的写入跟读取。

通过IsolatedStorageFile写入文件：

 1 private void WriteData()
 2         {
 3             IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForApplication();
 4             store.CreateDirectory("StoreFileTemp");
 5 
 6             using (IsolatedStorageFileStream storeStream = new IsolatedStorageFileStream("StoreFileTemp\\Test.txt", FileMode.OpenOrCreate, store))
 7             {
 8                 using (StreamWriter sw = new StreamWriter(storeStream))
 9                 {
10                     sw.WriteLine(txtWrite.Text);
11                 }
12             }
13         }

通过IsolatedStorageFile读取文件：

 1 private void ReadData()
 2         {
 3             IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForApplication();
 4             if (store.FileExists("StoreFileTemp\\Test.txt"))
 5             {
 6                 using (IsolatedStorageFileStream storeStream = new IsolatedStorageFileStream("StoreFileTemp\\Test.txt", FileMode.Open, store))
 7                 {
 8                     using (StreamReader sr = new StreamReader(storeStream))
 9                     {
10                         tbRead.Text = sr.ReadLine();
11                     }
12                 }
13             }
14         }
