释放由 ToolStripDropDownItem 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 ToolStripDropDownItem and optionally releases the managed resources.

 override void Dispose(bool disposing);
protected override void Dispose (bool disposing);
override this.Dispose : bool -> unit
Protected Overrides Sub Dispose (disposing As Boolean)


Boolean Boolean Boolean Boolean

true 表示释放托管资源和非托管资源;false 表示仅释放非托管资源。true to release both managed and unmanaged resources; false to release only unmanaged resources.


此方法由公共Dispose()方法Finalize和方法调用。This method is called by the public Dispose() method and the Finalize method. Dispose()调用受保护Dispose(Boolean)的方法, disposing并将参数true设置为。Dispose() invokes the protected Dispose(Boolean) method with the disposing parameter set to true. FinalizeDispose 设置disposingfalse的情况调用。Finalize invokes Dispose with disposing set to false.

当参数为 true 时,此方法释放该ToolStripDropDownItem引用的任何托管对象所持有的所有资源。 disposingWhen the disposing parameter is true, this method releases all resources held by any managed objects that this ToolStripDropDownItem 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.


Dispose 可以由其他对象多次调用。 Dispose can be called multiple times by other objects. 当重Dispose(Boolean)写时, 请注意不要引用先前在Dispose调用时已释放的对象。When 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Dispose(Boolean)的详细信息, 请参阅实现 Dispose 方法For more information about how to implement Dispose(Boolean), see Implementing a Dispose Method.
