c# FTP上传文件。

东西不是很复杂，不过百度出来的，貌似都是一种，代码太长了，复制都不想复制，来个简易版本的吧，直接贴代码。

   /// <summary>
        /// 上传ftp服务
        /// </summary>
        /// <param name="path">文件地址</param>
        /// <returns></returns>
        public string Upload(string path)
        {
            var client = new WebClient();
            client.Credentials = new NetworkCredential("fptuser", "ftppwd");//用户名和密码
            client.BaseAddress = "ftpurl";//ftp地址
            string ftpPath = client.BaseAddress + "/TestFileUpLoad/" + Guid.NewGuid();//上传fptp路径
            string returnPath = "";
            try
            {
                client.UploadFile(ftpPath, path);
                returnPath = ftpPath;
            }
            catch (Exception ex)
            {
                ///错误信息处理
            }
            return returnPath;
        }
