我最近在Unity中使用#region，＃endregion，＃if，＃endif等等问题一直存在问题。
我不记得究竟是什么版本的Unity开始，但每当我创建一个新项目时，我都不能使用区域。
它总是说有一个解析错误，然后说出类似“错误CS1027：预期`#endif'指令”
为了得到这个错误，这就是我所说的
#if !UNITY_EDITOR
#endif
如果我在语句之间包含代码，或者删除指令两边的所有空白空格都没关系。
我有另一个较旧的项目，我可以使用#regions和#if语句就好了，不确定改变了什么或如何修复它...我一直在谷歌搜索解决方案，似乎没有人否则有这个问题？它是monodevelop中的一个环境吗？白色空间？某处的字符无效？哈哈，我真的不知道为什么会这样，这让我发疯了。哈哈。
如果有人有任何建议，我很乐意听到他们的意见！
谢谢你的时间！
编辑： 以下是#regions在拖放脚本中不起作用的示例..（奖励，免费拖放和删除脚本！LOL）如果他们给你错误，也许只是注释掉这些地区..我不得不这样做。 ：（
Unity控制台错误：

答案 0 :(得分：3)
所以，关于你给出的例子。
我将它粘贴到普通Unity5项目中的文件HybFacebookExtensions.cs。它完美无缺 - 没有错误。
您的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。你手头有第二台机器进行测试吗？
#if !UNITY_EDITOR
Debug.Log("YO");
#endif
是一个正确的例子。
您可能会意外地从“调试”更改为“发布”。
请注意。你可以非常容易地混淆这些错误，
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
