IsolatedStorageFilePermission Class

Specifies the allowed usage of a private virtual file system. This class cannot be inherited.

Namespace:  System.Security.Permissions
Assembly:  mscorlib (in mscorlib.dll)

public final class IsolatedStorageFilePermission extends IsolatedStoragePermission

The common language runtime (CLR) uses this class to control access to isolated storage.

Isolated storage creates a unique storage area for use by an application or component. It provides true isolation in that the identity of an application uniquely determines the root of a virtual file system, which only that application can access. Thus, each application has its own file area automatically assigned to it. This file area is fully isolated from other applications, making it private to that application.

NoteNote:

There is no effect if you use Assert, PermitOnly, or Deny to add stack modifiers for usage or quota. Usage and quota are determined from evidence and a stack walk is not performed for demands, making the above operations ineffective.

The following example shows the use of members of the IsolatedStorageFilePermission class.
