【WP8】线程安全的StorageHelper

阅读更多关于【WP8】线程安全的StorageHelper

14-08-29 12:32更新：修复StorageHelper部分bug WP8以后提供了StorageFile的方式访问文件，StorageFile对文件的操作只提供了异步的支持，包括WP8.1 RT也没有对同步读写文件的支持，可以看出异步在移动开发中的重要性，而且Win8也是通过StorageFile进行文件操作的跟WP7上的IsolatedStorageFile相比，StorageFile使用起来并不方便，最近总结了一些资料，写了一个通用的类库 StorageFile默认是线程不安全的，如果多个线程同时对文件进行读写会抛出异常，例如多图的场景比较常见让StorageFile使用起来更加方便，同时提供了线程安全的异步操作，同时也对IsolatedStorageFile（Silverlight）进行了封装一、StorageFile要点：　　StorageFile 　　　　1、访问文件（两种方式） //访问安装目录下的test.txt文件，如果不存在，会抛出FileNotFoundException异常 //1、访问当前目录下的文件 var folder = Package.Current.InstalledLocation; var storageFile = await folder.GetFileAsync("test.txt"); //2、通过Uri访问文件
