我最近开始为 Windows 开发 kinect。我是 C# 的初学者,我希望你们能告诉我冒号前后的部分在 ---> “mainwindow:window”中是什么意思

我不知道“initializeComponent()”在做什么。即使当我评论它时,代码仍然可以正常工作,所以这实际上是在做什么,当我按 F12 查找它的定义时,它把我带到了名为“mainwindow.g.cs”的新文件

这不是 Kinect 特有的,而是您对它的 C# 有疑问的东西。

你的问题在哪里MainWindow : Window,那就是你的类被调用MainWindow,冒号表示C# 中的继承。也就是说,MainWindow是(或继承)的子类Window

至于InitializeComponent在这里查看答案:https ://stackoverflow.com/a/245881/23528
