代码如下:

	

	/// <summary>

	        /// 删除掉空文件夹

	        /// 所有没有子“文件系统”的都将被删除

	        /// </summary>

	        /// <param name="storagepath"></param>

	        public static void KillEmptyDirectory(String storagepath)

	        {

	            DirectoryInfo dir = new DirectoryInfo(storagepath);

	            DirectoryInfo[] subdirs = dir.GetDirectories("*.*", SearchOption.AllDirectories);

	            foreach (DirectoryInfo subdir in subdirs)

	            {

	                FileSystemInfo[] subFiles = subdir.GetFileSystemInfos();

	                if (subFiles.Count() == 0)

	                {

	                    subdir.Delete();

	                }

	            }

	        }
