IsolatedStorageFileStream Class
Part of my 2008 study notes for exam 70-536 (.NET Framework 2.0).
Overview
- Represents a sandbox location to store application specific data in.
- Assembly/Machine store for application-level data.
- Assembly/User store for user-level data.
- File paths are relative inside a store.
Good practice
- Don’t write your state to local .xml files everywhere on the system, but store them in an IsolatedStorage.
Examples
Using a Store
IsolatedStorageFile a = IsolatedStorageFile.GetMachineStoreForAssembly();
IsolatedStorageFileStream b = new IsolatedStorageFileStream("MyState.config", FileMode.OpenOrCreate, a);
StreamWriter c = new StreamWriter(b);
c.WriteLine("Hello World!");
c.Close();
foreach (var storeFile in a.GetFileNames("*"))
{
Console.WriteLine(storeFile);
}
IsolatedStorageFileStream d = new IsolatedStorageFileStream("MyState.config", FileMode.Open, a);
StreamReader e = new StreamReader(d);
Console.WriteLine(e.ReadToEnd());
e.Close();
