特效预览 如果我点击进入Prefab
之后再运行游戏 第一次运行出现
SerializedObjectNotCreatableException: Object at index 0 is null
UnityEditor.Editor.CreateSerializedObject () (at <13645689d8a341ecb7d4d455baae14a2>:0)

UnityEditor.GameObjectInspector.OnEnable () (at <13645689d8a341ecb7d4d455baae14a2>:0)

第二次运行
NullReferenceException: Object reference not set to an instance of an object
UnityEditor.GameObjectInspector.ClearPreviewCache () (at <13645689d8a341ecb7d4d455baae14a2>:0)
UnityEditor.GameObjectInspector.OnDisable () (at <13645689d8a341ecb7d4d455baae14a2>:0)

      if (printStr.Contains("//"))  //说明是注释
                continue;

上面那个语句有个疑问，如果是这种情况，是否就查找不出来了:

m_label.text = "永远的神";// 标题

代码转高亮Code字符串工具，需要将正常代码转换成带转义符，换行符，缩进符的string

Example_33_ProjectWindowItemOnGUI编辑器可能有可以改善的地方，当项目中的文件夹大小达到一定程度时（1g以上），此时如果导入或删除资源或者脚本编译时，编辑器的逻辑，会清掉之前所有计算的结果，然后重新计算所有文件夹的大小，会使得创建个新文件夹会等待个一两秒的时间，我觉得可以弄个缓存机制，保留之前的计算信息然后局部更新大小，猜测应该可以用文件夹的结构构造一个线段树然后局部更新？或者缓存，时间戳好像也可以

支持高亮代码块

为了支持预览EditorWindow无法绘制的相关内容

支持从OverViewEditorWindow填入相应参数自动生成Example代码

这边做了处理（ParticleSystemGameObjectEditor 160 行），但是在 Unity 2020.3.10f1 版本中，依然是不能拖拽到SceneView.
报错信息如下

希望可以寻求一些帮助，感谢。

借鉴Odin Overview的样式
