Unity 预处理器指令错误？
Unity Preprocessor Directive Error?
我最近在 Unity 中使用#region、#endregion、#if、#endif 等东西时遇到问题。
我不记得这是从哪个版本的 Unity 开始的，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，然后说这样的话“error CS1027: Expected `#endif' directive”
为了得到那个错误，这就是我输入的全部内容
#if !UNITY_EDITOR
#endif
无论我是在语句之间包含代码，还是去掉指令两边的所有空 space..
我有另一个较旧的项目，我可以很好地使用#regions 和#if 语句，但不确定发生了什么变化或如何修复它。我一直在谷歌搜索解决方案，看起来没有其他人有这个问题吗？是monodelop里的设置吗？白space？某个地方的字符无效？我真的不知道为什么会这样，这让我很生气，哈哈。
如果有人有任何建议，我很乐意听取他们的意见！
感谢您的宝贵时间！
编辑：
这是#regions 在拖放脚本中对我不起作用的示例。（奖金，免费拖放脚本！大声笑）如果它们给你错误，也许只是注释掉这些区域......我不得不这样做。 :(

因此，关于您给出的示例。
我把它粘贴到一个普通Unity5项目中的文件HybFacebookExtensions.cs。它运行完美 - 没有错误。
您的 Unity 安装可能有问题。
不幸的是，没有人能够猜出那里出了什么问题。您手头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。
您可能不小心从 Debug 更改为 Release。
注意。你可能会很困惑地得到这些错误，
如果您的代码只有简单的语法错误。
这很烦人。以下示例可能会导致此类异常错误：
public Class Teste()
{
.. you meant to put it in here ..
}
#if UNITY_EDITOR
#endif
