讀取資料夾下所有的資源名字

            for (int j = 0; j < files.Length; j++)

通過路徑載入圖片

        tx.LoadImage(getImageByte(path_name));

        Sprite sprite = SetSprites(tx);

        return sprite;
    }

通過資源名字或者路徑判斷資源型別（圖片或者其他）

 /// <summary>
    /// 是否為圖片
    /// </summary>
    /// <param name="path_name">完整路徑</param>
    /// <returns></returns>
    public bool IsImage(string path_name)
    {
        string[] s1 = path_name.Split('/');
        string imgtype = ".JPEG|.JPG|.PNG";
        string[] ImageType = imgtype.Split('|');
        for (int i = 0; i < ImageType.Length; i++)
        {
            if (s1[s1.Length - 1].Contains(ImageType[i]))
                return true;
        }
        return false;
    }
