ImageAttributes.Dispose 方法


释放由此 ImageAttributes 对象使用的所有资源。Releases all resources used by this ImageAttributes object.

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



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


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