.net - Windows 7 和 8 中的隔离存储位置是什么？

Question

我想将文件存储在我的 Windows 8 或 Windows 7 独立存储位置。？知道位置，我想在该位置放置一些文件。那么，如何获取隔离存储文件的位置..？

 using(IsolatedStorageFile isoPath=IsolatedStorageFile.GetUserStoreForApplication())
{
}

我们在 IsolatedStorageFile.GetUserStoreForApplication()... 上获得的位置是什么？

在这里您可以找到完整的解决方案。只需将代码复制/粘贴到新的 WPF 应用程序项目中即可。

不要忘记一些程序集参考，即

System.Web.Extension

System.Web.Script.Serialization

System.IO.IsolatedStorage；

您可以找到由路径创建的设置文件，例如

C:\Users\USER_NAME\AppData\Local\IsolatedStorage\cogrxuh4.gma\140esil0.t05\Url.bejzwgwbgheugcdwci5jbycjpt0p5rke\AssemFiles

在您的情况下，这部分"cogrxuh4.gma\140esil0.t05\Url.bejzwgwbgheugcdwci5jbycjpt0p5rke"可能会有所不同。

同样使用此类，您可以将所有设置本地保存在您拥有EXE文件的同一目录中。

最后，您将需要定义一些AppConfigurationManager可以异步实现所有作业的类。
