Question

我最近开始研究kinect for windows。我是C＃的初学者我希望你们中的任何一个人能告诉我结肠前后的部分是什么意思---＆gt;的 “主窗口：窗口”

我无法弄清楚“intializeComponent（）”正在做什么。即使我评论它时，代码仍然可以正常工作，这实际上是做什么的，当我按F12查找其定义时，它将我带到了名为“mainwindow.g.cs

的新文件”

这不是Kinect特有的，而是你对C＃事项有疑问的。

如果您的问题在MainWindow : Window左右，那么您的班级将被称为MainWindow，冒号表示inheritance in C#。也就是说，MainWindow是（或继承）Window的子类。

至于InitializeComponent，请在此处查看答案：https://stackoverflow.com/a/245881/23528
