 virtual void Dispose();
public void Dispose ();
abstract member Dispose : unit -> unit
override this.Dispose : unit -> unit
Public Sub Dispose ()



Dispose 使用完畢時,請呼叫 CancellationTokenRegistrationCall Dispose when you are finished using the CancellationTokenRegistration. Dispose 方法會將 CancellationTokenRegistration 保留在無法使用的狀態。The Dispose method leaves the CancellationTokenRegistration in an unusable state. 呼叫 Dispose之後,您必須釋放所有對 CancellationTokenRegistration 的參考,讓垃圾收集行程可以回收 CancellationTokenRegistration 所佔用的記憶體。After calling Dispose, you must release all references to the CancellationTokenRegistration so the garbage collector can reclaim the memory that the CancellationTokenRegistration was occupying.

在您釋放最後一個 Dispose 參考之前,請務必呼叫 CancellationTokenRegistrationAlways call Dispose before you release your last reference to the CancellationTokenRegistration. 否則工作窗格所使用的資源不會釋放,直到記憶體回收行程呼叫 CancellationTokenRegistration 物件的 Finalize 方法。Otherwise, the resources it is using will not be freed until the garbage collector calls the CancellationTokenRegistration object's Finalize method.
