是一个新事物。 土地网和来自德尔菲的背景,我习惯于在需要时以人工方式建立控制。
在网内,收集了垃圾,我猜测你不需要明确解除控制。
在我的案件(WinForms)中,我充满活力地把一个包含一些其他控制的花板的流放。 在某些情况下,我需要删除一些小组。 我为实现这一目标做了哪些工作。
flowPanel.Controls.Remove(thePanelToRemove);
这产生了必要的效果:小组从花名册上消失,但我看不到的是:垃圾收集者是否删除控制? 这将是理想的行为,因为我会创造许多控制手段,在用户删除时,更不用使用。 如果不是的话,我如何能够确保取消控制? 缩略语
flowPanel.Controls.Remove(thePanelToRemove);
thePanelToRemove.Free();
或类似?
答案:是,当需要记忆时,停车场收集器将取消控制。
更长的答复: 一些控制要求垃圾收集器释放资源。 这些控制实施可识别的接口,如果你不再需要,你应要求处置控制。 处置将清理这些未管理的资源。
This have the needed effect: the panel disappears from the flowLayoutPanel, but what I don t get is: does the garbage collector deletes the control?
是的,如果物体不属于范围,则有资格获得垃圾收集。 不要说什么。 免费方法。
假定控制没有其他东西提及,则在移除时,其参考数字将降至零,并将按预期收集垃圾。 这是简明的描述(如果你想读更多的话,以下链接),但作为
当然,控制下提及的任何
