PrintQueueStream.Dispose(Boolean) 方法

定义

释放由 PrintQueueStream 占用的非托管资源并(可选)释放托管资源。Releases the unmanaged resources that are used by the PrintQueueStream and optionally releases the managed resources.

protected:
 override void Dispose(bool A_0);
protected:
 override void Dispose(bool );
protected override void Dispose (bool A_0);
protected override void Dispose (bool );
[System.Runtime.ExceptionServices.HandleProcessCorruptedStateExceptions]
protected override void Dispose (bool );
[System.Runtime.ExceptionServices.HandleProcessCorruptedStateExceptions]
protected override void Dispose (bool A_0);
override this.Dispose : bool -> unit
override this.Dispose : bool -> unit
Protected Overrides Sub Dispose (A_0 As Boolean)
Protected Overrides Sub Dispose ( As Boolean)

参数

A_0
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.

属性

注解

此方法由 Finalize 方法调用。This method is called by the Finalize method. Dispose() 调用受保护的 Dispose(Boolean) 方法,并将未命名的布尔参数设置为 trueDispose() invokes the protected Dispose(Boolean) method with the unnamed Boolean parameter set to true. Finalize 调用未命名的布尔参数设置为 falseDisposeFinalize invokes Dispose with the unnamed Boolean parameter set to false.

当未命名的布尔参数 true时,此方法将释放此 PrintQueueStream 引用的任何托管对象所持有的所有资源。When the unnamed Boolean parameter is true, this method releases all resources that are held by any managed objects that this PrintQueueStream 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 Dispose(Boolean)时,请注意不要引用之前在对 Dispose的调用中释放的对象。When overriding Dispose(Boolean), be careful not to reference objects that were previously disposed of 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/implementing-dispose.md)。For more information about how to implement Dispose(Boolean), see [Implementing a Dispose Method](~/docs/standard/garbage-collection/implementing-dispose.md). 有关 DisposeFinalize()的详细信息,请参阅[清理非托管资源](~/docs/standard/garbage-collection/unmanaged.md)和[重写 Finalize 方法](https://docs.microsoft.com/previous-versions/dotnet/netframework-4.0/ddae83kx(v=vs.100))。For more information about Dispose and Finalize(), see [Cleaning Up Unmanaged Resources](~/docs/standard/garbage-collection/unmanaged.md) and [Overriding the Finalize Method](https://docs.microsoft.com/previous-versions/dotnet/netframework-4.0/ddae83kx(v=vs.100)).
