unity editor 获取指定路径下所有指定类型的文件

使用AssetDatabase.FindAssets获取指定路径下资源。

如下，获取指定路径下所有资源名：

 1         string[] pathArr = { ConstUtils.cfgPrefix_ActionTimeline };
 2         private Dictionary<string, string> names = new();
 3 
 4         public Dictionary<string, string> GetTimelineNames()
 5         {
 6             names.Clear();
 7 #if UNITY_EDITOR
 8             var assetsGuid = AssetDatabase.FindAssets("t:ActionTimelineProfile", pathArr);
 9             for (var i = 0; i < assetsGuid.Length; i++)
10             {
11                 var guid = assetsGuid[i];
12                 var path = AssetDatabase.GUIDToAssetPath(guid);
13                 var lastIndex = path.LastIndexOf('/');
14                 if (lastIndex >= 0)
15                 {
16                     var name = (path.Substring(lastIndex + 1)).Replace(".asset", "");
17                     names.Add(name, name);
18                 }
19             }
20 #endif
21             return names;
22         }
