Object.Finalize 메서드

정의

네임스페이스:

System

어셈블리:

System.Runtime.dll

Source:

Object.cs

가비지 컬렉션이 회수하기 전에 개체가 리소스를 해제하고 다른 정리 작업을 수행할 수 있게 합니다.

!Object ()

~Object ();

abstract member Finalize : unit -> unit
override this.Finalize : unit -> unit

Finalize ()

예제

다음 예제에서는 재정의 하는 개체가 Finalize 제거 될 때 메서드가 호출 되었는지 확인 합니다 Finalize . 애플리케이션을 프로덕션에서의 Finalize 개체에서 보유 하는 관리 되지 않는 리소스를 해제 메서드를 재정의 해야 합니다. 또한 C# 예제에서는 메서드를 재정의하는 대신 소멸자를 Finalize 제공합니다.
