Form.cs和Form.Designer.cs其实是一个类，Visual Studio为了让我们方便管理，用partial关键字把窗体类给拆开了，Form.Designer.cs存放的是窗体的布局，你的窗体定义了哪些控件，那些控件的名字、属性等等，都是存放在Form.Designer.cs里面的，而Form.cs则是用来存放处理方法的，比如你的按钮点击事件绑定了Button_Click这个方法，...

5、MainForm.cs窗体设计器中，放入三个Panel控件分别命名为[panel_Left、panel_Right、panel_Fill]，在panel_Left右边添加一个分隔控件Splitter{Dock=Left}、在panel_Right左边添加一个Splitter{Dock=Right}。然后将三个panel的Dock属性按名字进行设置，让其呈现左中右效果，并由我们的分隔控件隔开，方便伸缩三个panel的大小。7、本案例只是简单抛砖引玉，如需商业应用，请自行深入探究。
