C# 遍历指定目录下的所有文件及文件夹以及遍历数据库的方法

// DirectoryInfo di = new DirectoryInfo(@"D:\Test");
// FindFile(di);
static void FindFile(DirectoryInfo di)
{
　　FileInfo[] fis = di.GetFiles();
　　for (int i = ; i < fis.Length; i++)
　　{
　　　　Console.WriteLine("文件：" + fis[i].FullName);
　　}
　　DirectoryInfo[] dis = di.GetDirectories();
　　for (int j = ; j < dis.Length; j++)
　　{
　　　　Console.WriteLine("目录：" + dis[j].FullName);
　　　　FindFile(dis[j]);
　　}
}

根据父级遍历全部数据

       BaseOrganizeManager organizeManager = new BaseOrganizeManager();
        int count = ;
        JsonResult<string> reult = null;
        void FindChild(List<BaseOrganizeEntity> organizeEntities)
        {
            foreach (var item in organizeEntities)
            {
                if (item.Enabled ==  || item.DeletionStateCode == )
                {
                    continue;
                }
                reult = CaiNiaoAPIUtilities.SyncOrganizeToCaiNiao(item);
                System.Console.WriteLine(count + ",执行同步：" + item.FullName + "," + DateTime.Now);
                System.Console.WriteLine("返回" + reult.Data + "," + DateTime.Now);
                count++;

            }
            List<BaseOrganizeEntity> organizeChids = null;
            string where = string.Empty;
            foreach (var item in organizeEntities)
            {
                where = BaseOrganizeEntity.FieldParentId + " = '" + item.Id + "' ";
                organizeChids = organizeManager.GetList<BaseOrganizeEntity>(where);
                FindChild(organizeChids);
            }
        }

            string where = BaseOrganizeEntity.FieldParentId + " IS NULL ";
            List<BaseOrganizeEntity> organizeEntities = organizeManager.GetList<BaseOrganizeEntity>(where);
            FindChild(organizeEntities);
