Image.Dispose Image.Dispose Image.Dispose Image.Dispose Method

定义

释放此 Image 使用的所有资源。Releases all resources used by this Image.

重载

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

释放此 Image 使用的所有资源。Releases all resources used by this Image.

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

释放由 Image 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 Image and optionally releases the managed resources.

注解

备注

每次释放对 Dispose 的最后一个引用前,均应调用 ImageAlways call Dispose before you release your last reference to the Image. 否则,在垃圾回收器调用 Image 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 Image object's Finalize method.

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

释放此 Image 使用的所有资源。Releases all resources used by this Image.

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

实现

注解

通过调用Image方法,可以将此使用的资源重新分配给其他目的。 DisposeCalling the Dispose method allows the resources used by this Image to be reallocated for other purposes.

在完成使用 Dispose 后,应调用 ImageCall Dispose when you are finished using the Image. Dispose 方法使 Image 处于不可用状态。The Dispose method leaves the Image in an unusable state. 调用Dispose后,必须释放对的Image所有引用,以便垃圾回收器能够Image回收占用的内存。After calling Dispose, you must release all references to the Image so the garbage collector can reclaim the memory that the Image 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.

释放由 Image 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 Image and optionally releases the managed resources.

 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

Boolean Boolean Boolean 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.
