Unity3d 枚举某个目录下所有资源

    //枚举所有GameObject在这个目录
    //path是相对于Application.dataPath的 例如 Assets/Res/UI/
    public static IEnumerable<GameObject> EnumGameObjectAtPath(string path)
    {
        var guids = AssetDatabase.FindAssets("t:GameObject", new string[] { path });
        foreach (var guid in guids)
        {
            var p = AssetDatabase.GUIDToAssetPath(guid);
            var go = AssetDatabase.LoadAssetAtPath(p, typeof(GameObject)) as GameObject;
            if (null != go)
            {
                yield return go;
            }
        }
    }

    //枚举所有资源
    //path是相对于Application.dataPath的 例如 Assets/Res/UI/
    public static IEnumerable<T> EnumAssetAtPath<T>(string path)
        where T : Object
    {
        var guids = AssetDatabase.FindAssets("t:Object", new string[] { path });
        foreach (var guid in guids)
        {

            var go = AssetDatabase.LoadAssetAtPath(p, typeof(System.Object)) as T;
            if (null != go)
            {
                yield return go;
            }
        }
    }

    //递归枚举这个目录下的GameObject的所有T类型组件
    //path是相对于Application.dataPath的 例如 Assets/Res/UI/
    public static IEnumerable<T> EnumComponentRecursiveAtPath<T>(string path)
        where T : UnityEngine.Component
