SymmetricAlgorithm.Dispose SymmetricAlgorithm.Dispose SymmetricAlgorithm.Dispose SymmetricAlgorithm.Dispose Method

定义

释放 SymmetricAlgorithm 类的当前实例所使用的所有资源。Releases all resources used by the current instance of the SymmetricAlgorithm class.

重载

Dispose() Dispose() Dispose() Dispose()

释放 SymmetricAlgorithm 类的当前实例所使用的所有资源。Releases all resources used by the current instance of the SymmetricAlgorithm class.

Dispose(Boolean) Dispose(Boolean) Dispose(Boolean) Dispose(Boolean)

释放由 SymmetricAlgorithm 占用的非托管资源,还可以另外再释放托管资源。Releases the unmanaged resources used by the SymmetricAlgorithm and optionally releases the managed resources.

Dispose() Dispose() Dispose() Dispose()

释放 SymmetricAlgorithm 类的当前实例所使用的所有资源。Releases all resources used by the current instance of the SymmetricAlgorithm class.

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

实现

注解

在完成使用 Dispose 后,应调用 SymmetricAlgorithmCall Dispose when you are finished using the SymmetricAlgorithm. Dispose 方法使 SymmetricAlgorithm 处于不可用状态。The Dispose method leaves the SymmetricAlgorithm in an unusable state. 在调用Dispose,必须释放对所有引用SymmetricAlgorithm这样垃圾回收器才能收回内存的SymmetricAlgorithm占用。After calling Dispose, you must release all references to the SymmetricAlgorithm so the garbage collector can reclaim the memory that the SymmetricAlgorithm was occupying.

有关详细信息,请参阅清理了非托管资源实现 Dispose 方法For more information, see Cleaning Up Unmanaged Resources and Implementing a Dispose Method.

备注

每次释放对 Dispose 的最后一个引用前,均应调用 SymmetricAlgorithmAlways call Dispose before you release your last reference to the SymmetricAlgorithm. 否则,在垃圾回收器调用 SymmetricAlgorithm 对象的 Finalize 方法之前,该对象正在使用的资源不会被释放。Otherwise, the resources it is using will not be freed until the garbage collector calls the SymmetricAlgorithm object's Finalize method.

释放由 SymmetricAlgorithm 占用的非托管资源,还可以另外再释放托管资源。Releases the unmanaged resources used by the SymmetricAlgorithm and optionally releases the managed resources.

protected:
 virtual void Dispose(bool disposing);
protected virtual void Dispose (bool disposing);
abstract member Dispose : bool -> unit
override this.Dispose : bool -> unit
Protected Overridable Sub Dispose (disposing As Boolean)

参数

disposing
Boolean Boolean Boolean Boolean

true 表示释放托管资源和非托管资源;false 表示仅释放非托管资源。true to release both managed and unmanaged resources; false to release only unmanaged resources.

注解

调用此方法由公共Dispose()方法和Finalize方法。This method is called by the public Dispose() method and the Finalize method. Dispose() 调用受保护Dispose(Boolean)方法替换disposing参数设置为trueDispose() invokes the protected Dispose(Boolean) method with the disposing parameter set to true. Finalize 调用Disposedisposing设置为falseFinalize invokes Dispose with disposing set to false.

disposing 参数为 true 时,此方法释放该 SymmetricAlgorithm 引用的、由任何托管对象持有的全部资源。When the disposing parameter is true, this method releases all resources held by any managed objects that this SymmetricAlgorithm references. 此方法调用每个引用对象的 Dispose() 方法。This method invokes the Dispose() method of each referenced object.

继承者说明

Dispose 可以由其他对象多次调用。 Dispose can be called multiple times by other objects. 重写时Dispose(Boolean),请小心不要引用在早期调用之前释放对象DisposeWhen overriding Dispose(Boolean), be careful not to reference objects that have been previously disposed in an earlier call to Dispose. 有关如何实现详细信息Dispose(Boolean),请参阅实现 Dispose 方法For more information about how to implement Dispose(Boolean), see Implementing a Dispose Method.
