TreeView.Dispose(Boolean) 方法

定义

释放由 TreeView 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 TreeView and optionally releases the managed resources.

protected:
 override void Dispose(bool disposing);
protected override void Dispose (bool disposing);
override this.Dispose : bool -> unit
Protected Overrides 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 falsetrue 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 trueDispose invokes the protected Dispose(Boolean) method with the disposing parameter set to true. FinalizeDispose在设置为的情况调用 disposing falseFinalize invokes Dispose with disposing set to false.

disposing 参数为 true 时,此方法释放该引用的任何托管对象所持有的所有资源 TreeViewWhen the disposing parameter is true, this method releases all resources held by any managed objects that this TreeView references. 此方法将调用每个被引用对象的 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. 当重写时, Dispose(Boolean) 请注意不要引用先前在调用时已释放的对象 DisposeWhen 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).
