创建文件夹

//文件夹路径        string fulpath = Application.streamingAssetsPath + "/myy/";        string fulpath1 = Application.streamingAssetsPath + "/photo/ui/";//判断文件夹存不存在,不存在就创建        if (!Directory.Exists(fulpath))        {            Directory.CreateDirectory(fulpath);            Directory.CreateDirectory(fulpath1);        }

遍历文件夹里面的文件

if (Directory.Exists(fullPath))        {  //按钮                       DirectoryInfo direction = new DirectoryInfo(fullPath);            FileInfo[] files = direction.GetFiles("*.xml", SearchOption.AllDirectories);            //图片            DirectoryInfo photo = new DirectoryInfo(fullPathPhoto);            FileInfo[] fileoto = photo.GetFiles("*.png", SearchOption.AllDirectories);            // Debug.Log(files.Length);            for (int i = 0; i < files.Length; i++)            {                if (files[i].Name.EndsWith(".meta"))                {                    continue;                }                //if (fileoto[i].Name.EndsWith(".meta")) {                //    continue;                //}                string str = files[i].Name;                string clone = ".xml";                Regex r = new Regex(clone);                Match m = r.Match(str);                //图片                string oto = fileoto[i].Name;                string clo = ".png";                Regex ro = new Regex(clo);                Match mo = ro.Match(oto);                if (m.Success && mo.Success)                {                    str = str.Replace(clone, "");                    oto = oto.Replace(clo, "");                                  }            }            }
