abstract class

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.
