CryptoStream.Dispose(Boolean) 方法


释放 CryptoStream 使用的非托管资源,并选择性地释放托管资源。Releases the unmanaged resources used by the CryptoStream and optionally releases the managed resources.

 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)



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 falsetrue to release both managed and unmanaged resources; false to release only unmanaged resources.


此方法由 public 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,并将释放参数设置为 trueDispose() invokes the protected Dispose(Boolean) method with the disposing parameter set to true. Finalize 将释放设置为 Dispose,调用 falseFinalize invokes Dispose with disposing set to false.

disposing 参数为 true 时,此方法释放该 CryptoStream 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 CryptoStream 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.


Dispose 可以由其他对象多次调用。 Dispose can be called multiple times by other objects. 重写 Dispose(Boolean)时,请注意不要引用先前在调用 Dispose之前已释放的对象。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 Dispose(Boolean)的详细信息,请参阅[实现 Dispose 方法](~/docs/standard/garbage-collection/。For more information about how to implement Dispose(Boolean), see [Implementing a Dispose Method](~/docs/standard/garbage-collection/ 有关 DisposeFinalize的详细信息,请参阅[清理非托管资源](~/docs/standard/garbage-collection/。For more information about Dispose and Finalize, see [Cleaning Up Unmanaged Resources](~/docs/standard/garbage-collection/
