C# code

        /// <summary>        /// 删除文件        /// </summary>        /// <param name="path">路径</param>        /// <param name="cred">通行证</param>        /// <returns></returns>        public static bool FtpDeleteFile(string path, ICredentials cred)        {            FtpWebRequest req = (FtpWebRequest)WebRequest.Create(path);            if (cred != null)                req.Credentials = cred;            req.Method = WebRequestMethods.Ftp.DeleteFile;            req.KeepAlive = false;            try            {                req.GetResponse().Close();                return true;            }            catch (WebException ex)            {                log.Error("FtpDeleteFile Error:" + ex.Message);                return false;            }        }
