由于主窗体的ShowInTaskBar = false，所以不得不使用FindWindow来获取，IntPtr FindWindow(string lpClassName, string lpWindowName)，但是主窗体的标题lpWindowName可能会变动，所以想通过窗体的类名lpClassName来获取，而我的主窗体是C#写的程序，这个lpClassName应该不会是主窗体的类全名（Namespace.ClassName）字符串....可是百度和谷歌了大半天，没有相关的例子.....苦闷中，哪位大侠能拔刀相助，先谢了！
类似 WindowsForms10.Window.8.app.0.378734a
如果能够用“this.Handle”，就说明已经得到窗体的对象了，还需要这么麻烦么？

2、获取主界面窗口句柄Process.MainWindowHandle
