When implementing this method in an inherited class the following template should be used; protected override void dispose( bool disposeManagedResources ) { if ( !isDisposed ) { if ( disposeManagedResources ) { // Dispose managed resources. } // There are no unmanaged resources to release, but // if we add them, they need to be released here. } // If it is available, make the call to the // base class's Dispose(Boolean) method base.dispose( disposeManagedResources ); }
