C# 将windows窗体转换为windows Metro窗体

我已经用普通的windows格式编写了一个桌面应用程序，它运行得很好。后来我试着把它改成地铁的形式，因为它看起来很现代。在控件名上做了一些小改动后，我使用了旧范式中的大部分代码。但是表单大小调整功能块在启动应用程序时抛出“System.NullReferenceException”。但是在评论了调整大小事件之后，它工作得很好

更新：引发NullReferenceException，因为Form1_Resize事件发生在Form1_Load事件之前。在我更改窗口布局（通过拖动或最大化窗口大小）之前，不应调用Form1_Resize事件。但在Form1 comp之前启动应用程序时自动调用Resize事件
