EventSource.Dispose 方法

定义

释放 EventSource 类的当前实例所使用的所有资源。Releases all resources used by the current instance of the EventSource class.

重载

Dispose()

释放 EventSource 类的当前实例所使用的所有资源。Releases all resources used by the current instance of the EventSource class.

Dispose(Boolean)

释放 EventSource 类使用的非托管资源,并可以选择释放托管资源。Releases the unmanaged resources used by the EventSource class and optionally releases the managed resources.

Dispose()

释放 EventSource 类的当前实例所使用的所有资源。Releases all resources used by the current instance of the EventSource class.

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

适用于

Dispose(Boolean)

释放 EventSource 类使用的非托管资源,并可以选择释放托管资源。Releases the unmanaged resources used by the EventSource class 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

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. Finalize``Dispose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 EventSource 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 EventSource 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. 重写时 Dispose(Boolean) ,请注意不要引用先前在 Dispose 方法调用中已释放的对象 DisposeWhen overriding Dispose(Boolean), be careful not to reference objects that have been previously disposed in an earlier the Dispose Method 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).
