PrintSystemObjectPropertiesChangedEventArgs.Dispose 方法

定义

释放由 PrintSystemObjectPropertiesChangedEventArgs 对象使用的资源。Releases the resources used by the PrintSystemObjectPropertiesChangedEventArgs object.

重载

Dispose()

释放由 PrintSystemObjectPropertiesChangedEventArgs 对象使用的所有资源。Releases all resources used by the PrintSystemObjectPropertiesChangedEventArgs object.

Dispose(Boolean)

释放由 PrintSystemObjectPropertiesChangedEventArgs 对象占用的非托管资源,还可以选择释放托管资源。Releases the unmanaged resources that are used by the PrintSystemObjectPropertiesChangedEventArgs object and optionally releases the managed resources.

Dispose()

释放由 PrintSystemObjectPropertiesChangedEventArgs 对象使用的所有资源。Releases all resources used by the PrintSystemObjectPropertiesChangedEventArgs object.

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

实现

注解

在完成使用 Dispose() 后,应调用 PrintSystemObjectPropertiesChangedEventArgsCall Dispose() when you are finished using the PrintSystemObjectPropertiesChangedEventArgs. Dispose() 方法使 PrintSystemObjectPropertiesChangedEventArgs 处于不可用状态。The Dispose() method leaves the PrintSystemObjectPropertiesChangedEventArgs in an unusable state. 调用 Dispose()后,必须释放对 PrintSystemObjectPropertiesChangedEventArgs 的所有引用,以便垃圾回收器可以回收 PrintSystemObjectPropertiesChangedEventArgs 占用的内存。After calling Dispose(), you must release all references to the PrintSystemObjectPropertiesChangedEventArgs so that the garbage collector can reclaim the memory that the PrintSystemObjectPropertiesChangedEventArgs was occupying. 有关详细信息,请参阅清理非托管资源实现 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 PrintSystemObjectPropertiesChangedEventArgsAlways call Dispose() before you release your last reference to the PrintSystemObjectPropertiesChangedEventArgs. 否则,在垃圾回收器调用 PrintSystemObjectPropertiesChangedEventArgs 对象的 Finalize 方法之前,不会释放它所使用的资源。Otherwise, the resources it is using are not freed until the garbage collector calls the Finalize method of the PrintSystemObjectPropertiesChangedEventArgs object.

Dispose(Boolean)

释放由 PrintSystemObjectPropertiesChangedEventArgs 对象占用的非托管资源,还可以选择释放托管资源。Releases the unmanaged resources that are used by the PrintSystemObjectPropertiesChangedEventArgs object and optionally releases the managed resources.

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

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 Dispose 并将参数设置为 falseFinalize invokes Dispose with the parameter set to false.

true布尔参数时,此方法将释放此 PrintSystemObjectPropertiesChangedEventArgs 引用的任何托管对象所持有的所有资源。When the Boolean parameter is true, this method releases all resources that are held by any managed objects that this PrintSystemObjectPropertiesChangedEventArgs 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)).
