我的任务
分享这个问题很简单，但是蹊跷！我在线等着：）
我把我的程序贴上来。
很简单的一个Simple程序。
问题出在最小化时
为什么最小化的时候在Taskbar延迟显示？我是新手

我没有测试你的例子，没有你的代码哦，呵呵。

3Q不过我这里还是不行啊。
能把代码贴上来吗？

刚才试验了下，如果将this.ShowInTaskbar = true
在this.WindowState = FormWindowState.Minimized之后运行就会出现你所说的延迟显示的现象，
但是如果在this.WindowState = FormWindowState.Minimized之前就将this.ShowInTaskbar = true，那么就不会出现该延迟。
我理解的是：前者最小化的时候，判断该窗体不在状态栏显示，所以隐藏了，而后面的代码却又将该窗体的状态栏显示设置为true，所以重新绘制显示出来，这次重绘就是延迟的原因。
个人看法，请大家指教

这个我试过呀，不过点最小化按钮到TaskBar显示这段时间哪里都不走。所有断点没反应啊

Oh my God !
我发现
设置
ShowInTaskbar
WindowState
这两个属性的时候会触发Resize和sizeChanged事件。
现在最小化没有问题了，可是恢复大小的时候我想让状态栏消失。
可是如果在Resize事件处理方法中写ShowInTaskbar=false
那这句话又会触发Resize事件，这样就会进入死循环。
