Unity3d中如何查找一個腳本被掛在那些預設上面？

用一個腳本函數可以獲取到選擇的腳本文件被哪些預設和場景引用

[MenuItem("Assets/Tool/GetReference")]
 static void GetReference()
   {
        string target = "";
        if (Selection.activeObject != null)
            target = AssetDatabase.GetAssetPath(Selection.activeObject);
        if (string.IsNullOrEmpty(target))
            return;
        string[] files = Directory.GetFiles(Application.dataPath, "*.prefab", SearchOption.AllDirectories);
        string[] scene = Directory.GetFiles(Application.dataPath, "*.unity", SearchOption.AllDirectories);
        
        List<Object> filelst = new List<Object>();
        for (int i = 0; i < files.Length; i++)
        {
            string[] source = AssetDatabase.GetDependencies(new string[] { files[i].Replace(Application.dataPath, "Assets") });
            for (int j = 0; j < source.Length; j++)
            {
                if (source[j] == target)
                    filelst.Add(AssetDatabase.LoadMainAssetAtPath(files[i].Replace(Application.dataPath, "Assets")));
            }
        }
        for (int i = 0; i < scene.Length; i++)
        {
            string[] source = AssetDatabase.GetDependencies(new string[] { scene[i].Replace(Application.dataPath, "Assets") });
            for (int j = 0; j < source.Length; j++)
            {
                if (source[j] == target)
                    filelst.Add(AssetDatabase.LoadMainAssetAtPath(scene[i].Replace(Application.dataPath, "Assets")));
            }
        }
        Selection.objects = filelst.ToArray();
    }
