Class 文件用记事本打开，电脑重启后完全空白

Question

我朋友的 GameElements.cs 似乎以某种方式损坏了。我们都在同一个 class 学习，他把他的项目发给我，我也打不开文件。我无法对他的解决方案进行故障排除，因为他使用的是 XNA 而我使用的是 MonoGame。

可悲的是，他没有任何备份（尽管这样他会学到很多东西）而且我们都不熟悉 Visual Studio 和编程，因为我们课程刚开始几个月。

文件仍然是 12kb，尽管我只能 select/copy 空格。我不知道是否可以从中恢复代码，文件中显然有数据。

这是一个 link 下载整个解决方案，尽管有问题的损坏文件是 "GameElements.cs"。如果有人能够恢复代码，我们都将不胜感激！ http://www.filedropper.com/xnabus

请参阅下面的 GameElements.cs 中的代码。希望这可以帮助：）。您可以使用任何 .Net 反汇编程序来执行此操作。我使用了 ILSpy 并从 XNA bus.exe 文件中反编译了您的代码。

请注意，有时类或方法的名称可能会出现一些小问题。因此，请完整检查一次代码以确保这一点。
