PrintSystemObject.Dispose 方法

定义

释放由 PrintSystemObject 占用的资源。Releases the resources used by the PrintSystemObject.

重载

Dispose()

释放由 PrintSystemObject 使用的所有资源。Releases all resources used by the PrintSystemObject.

Dispose(Boolean)

释放由 PrintSystemObject 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 PrintSystemObject and optionally releases the managed resources.

Dispose()

释放由 PrintSystemObject 使用的所有资源。Releases all resources used by the PrintSystemObject.

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 PrintSystemObjectCall Dispose() when you are finished using the PrintSystemObject. Dispose() 方法使 PrintSystemObject 处于不可用状态。The Dispose() method leaves the PrintSystemObject in an unusable state. 调用Dispose()后,必须释放对的PrintSystemObject所有引用,以便垃圾回收器能够PrintSystemObject回收占用的内存。After calling Dispose(), you must release all references to the PrintSystemObject so the garbage collector can reclaim the memory that the PrintSystemObject 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 PrintSystemObjectAlways call Dispose() before you release your last reference to the PrintSystemObject. 否则,在垃圾回收器调用 PrintSystemObject 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 PrintSystemObject object's Finalize method.

Dispose(Boolean)

释放由 PrintSystemObject 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 PrintSystemObject and optionally releases the managed resources.

protected:
 virtual void Dispose(bool );
[System.Runtime.ExceptionServices.HandleProcessCorruptedStateExceptions]
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

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.

属性

注解

此方法由公共Dispose()方法Finalize和方法调用。This method is called by the public Dispose() method and the Finalize method. Dispose()调用受保护Dispose(Boolean)的方法,并将未命名的true布尔参数设置为。Dispose() 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.

如果布尔参数为, true此方法将释放该PrintSystemObject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 held by any managed objects that this PrintSystemObject 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,请注意不要引用在以前调用 Dispose 时已释放的对象。When overriding Dispose(Boolean), be careful not to reference objects that have been 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)).
