The following code example is intended to show the behavior of the ToXml method, not to demonstrate its use. In general, the methods of permission classes are used by the security infrastructure and are not intended for use in applications. However, the following code example shows how the method performs if you execute the method from your code. For the complete code example, see the FileDialogPermission class.

private bool ToFromXmlDemo()

    bool returnValue = true;

    fileDialogPerm2 = new FileDialogPermission(PermissionState.None);
    Console.WriteLine("Result of ToFromXml = " +

    return returnValue;

// ToXml creates an XML encoding of the permission and its current 
// state; FromXml reconstructs a
// permission with the specified state from the XML encoding.
