Synopsis

public abstract class IsolatedStoragePermission : System.Security.CodeAccessPermission : IUnrestrictedPermission {
// Public Constructors
   public IsolatedStoragePermission(PermissionState state);
// Public Instance Properties
   public IsolatedStorageContainment UsageAllowed{set; get; }
   public long UserQuota{set; get; }
// Public Instance Methods
   public override void FromXml(System.Security.SecurityElement esd);
 // overrides CodeAccessPermission
   public bool IsUnrestricted(  );     
// implements IUnrestrictedPermission
   public override SecurityElement ToXml(  );   
// overrides CodeAccessPermission
}

This abstract class provides the base class from which all types of isolated storage permission classes derive. Currently, there is only one concrete isolated storage permission implementation: IsolatedStorageFilePermission. The unique features of the IsolatedStoragePermission class, which all derived classes inherit, are the UsageAllowed and UserQuota properties. The UsageAllowed property represents the scope of store code can obtain, and UserQuota specifies the store’s maximum permitted size.
