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

重载

Dispose() Dispose() Dispose() Dispose()

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

Dispose(Boolean) Dispose(Boolean) Dispose(Boolean) Dispose(Boolean)

释放由 TextReader 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 TextReader and optionally releases the managed resources.

Dispose() Dispose() Dispose() Dispose()

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

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

实现

注解

在完成使用 Dispose 后,应调用 TextReaderCall Dispose when you are finished using the TextReader. Dispose 方法使 TextReader 处于不可用状态。The Dispose method leaves the TextReader in an unusable state. 在调用Dispose,必须释放对所有引用TextReader这样垃圾回收器才能收回内存的TextReader占用。After calling Dispose, you must release all references to the TextReader so the garbage collector can reclaim the memory that the TextReader was occupying.

有关详细信息,请参阅清理了非托管资源实现 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 TextReaderAlways call Dispose before you release your last reference to the TextReader. 否则,在垃圾回收器调用 TextReader 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 TextReader object's Finalize method.

Dispose(Boolean) Dispose(Boolean) Dispose(Boolean) Dispose(Boolean)

释放由 TextReader 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 TextReader and optionally releases the managed resources.

protected:
 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)

参数

disposing
Boolean Boolean Boolean Boolean

true (如果释放托管资源和非托管资源);如果仅释放非托管资源,则为 falseto release both managed and unmanaged resources; false to release only unmanaged resources.

注解

调用此方法由公共Dispose方法和Finalize方法。This method is called by the public Dispose method and the Finalize method. 默认情况下,此方法指定disposing参数作为trueBy default, this method specifies the disposing parameter as true. Finalize 指定disposing参数作为falsespecifies the disposing parameter as false.

disposing 参数为 true 时,此方法释放该 TextReader 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 TextReader 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 可以多次调用由其他对象。can be called multiple times by other objects. 重写此方法时, 请小心不要引用已经释放的早期调用中的对象DisposeWhen overriding this method, be careful not to reference objects that have been previously disposed of in an earlier call to Dispose. 有关如何实现此方法的详细信息,请参阅实现 Dispose 方法For more information about how to implement this method, see Implementing a Dispose Method.
