HashAlgorithm.Dispose 方法
定义
释放 HashAlgorithm 类的当前实例所使用的所有资源。Releases all resources used by the current instance of the HashAlgorithm class.
重载
| Dispose() |
释放 HashAlgorithm 类的当前实例所使用的所有资源。Releases all resources used by the current instance of the HashAlgorithm class. |
| Dispose(Boolean) |
释放由 HashAlgorithm 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 HashAlgorithm and optionally releases the managed resources. |
Dispose()
释放 HashAlgorithm 类的当前实例所使用的所有资源。Releases all resources used by the current instance of the HashAlgorithm class.
public:
virtual void Dispose();public void Dispose ();abstract member Dispose : unit -> unit
override this.Dispose : unit -> unitPublic Sub Dispose ()实现
注解
在完成使用 Dispose 后，应调用 HashAlgorithm。Call Dispose when you are finished using the HashAlgorithm. Dispose 方法使 HashAlgorithm 处于不可用状态。The Dispose method leaves the HashAlgorithm in an unusable state. 调用后 Dispose ，必须释放对的所有引用， HashAlgorithm 以便垃圾回收器能够回收占用的内存 HashAlgorithm 。After calling Dispose, you must release all references to the HashAlgorithm so the garbage collector can reclaim the memory that the HashAlgorithm was occupying.
有关详细信息，请参阅 清理非托管资源 和 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 HashAlgorithm。Always call Dispose before you release your last reference to the HashAlgorithm. 否则，在垃圾回收器调用 HashAlgorithm 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 HashAlgorithm object's Finalize method.
适用于
Dispose(Boolean)
释放由 HashAlgorithm 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 HashAlgorithm 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 -> unitProtected Overridable Sub Dispose (disposing As Boolean)参数
- disposing
- Boolean
若要释放托管资源和非托管资源，则为 true；若仅释放非托管资源，则为 false。true to release both managed and unmanaged resources; false to release only unmanaged resources.
注解
此方法由公共 Dispose() 方法和 Finalize 方法调用。This method is called by the public Dispose() method and the Finalize method. Dispose() 调用受保护的 Dispose(Boolean) 方法，并将 disposing 参数设置为 true 。Dispose() invokes the protected Dispose(Boolean) method with the disposing parameter set to true. Finalize``Dispose在设置为的情况调用 disposing false 。Finalize invokes Dispose with disposing set to false.
当 disposing 参数为 true 时，此方法释放该 HashAlgorithm 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 HashAlgorithm 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) ，请注意不要引用先前在调用时已释放的对象 Dispose 。When overriding Dispose(Boolean), be careful not to reference objects that have been previously disposed in an earlier call to Dispose. 有关如何实现的详细信息 Dispose(Boolean) ，请参阅 [实现 Dispose 方法](/dotnet/standard/garbage-collection/implementing-dispose)。For more information about how to implement Dispose(Boolean), see [Implementing a Dispose Method](/dotnet/standard/garbage-collection/implementing-dispose).
