When a new timer is created, it is disabled; that is, Enabled is set to false. To enable the timer, call the Start method or set Enabled to true.
If the timer is disabled and the timer is out of scope, the timer will be disposed when garbage collection occurs. If the timer is enabled, even if it is out of scope, it is not subject to garbage collection.
