Unity预处理器指令错误？

Question

我最近在使用Unity中的#region，#endregion，#if，#endif等类似的东西时遇到了问题。

我不记得刚开始的Unity版本是什么，但是每当我创建一个新项目时，我根本无法使用区域。

它总是说，有一个解析错误，然后说这样的事情“错误CS1027：预计`#ENDIF”指令”

为了得到这个错误，这是所有我把

#if !UNITY_EDITOR 
#endif 

，如果我有语句之间的代码，或剥离周围的指令两边都是空的空间没关系..

我有另外一个，旧的项目，我可以使用#regions和＃如果陈述在f不知道发生了什么变化或如何解决它..我一直在搜索解决方案，似乎没有人会遇到这个问题？这是一个monodevelop的设置吗？白色空间？无效字符的地方？我真的不知道为什么会发生这种情况，这让我很生气，哈哈。

如果有人有任何建议，我很乐意听到他们！

谢谢你的时间！

所以，对实施例YOU GIVE。

I将其粘贴到一个普通的Unity5项目中的文件HybFacebookExtensions.cs。它完美的工作 - 没有错误。

Unity安装可能存在问题。

不幸的是，没有人能够猜到那里出了什么问题。你有第二台机器可以测试吗？

---

#if !UNITY_EDITOR 
Debug.Log("YO"); 
#endif 

是一个正确的例子。

很可能你意外地从Debug改为Release。

注意。如果你的代码只有简单的语法错误，你可以非常困惑地得到这些错误，

。

这很烦人。以下示例可能导致此类异常错误：

public Class Teste() 
{ 
.. you meant to put it in here .. 
} 
#if UNITY_EDITOR 
#endif
