ftpUriString = "ftp://" + textBox1.Text;
            FtpWebRequest request = (FtpWebRequest)FtpWebRequest.Create(ftpUriString);
            string ftpAccount = "ftp";//ftp账户
            string ftpPwd = "123456";//ftp密码
            request.Credentials = new NetworkCredential(ftpAccount, ftpPwd);
            request.Method = WebRequestMethods.Ftp.ListDirectoryDetails;
            FtpWebResponse response = null;
            try
            {
                MessageBox.Show("ABCDE");
                response = (FtpWebResponse)request.GetResponse();
                //return response;
                MessageBox.Show("得到返回");
            }
            catch (WebException err)
            {
                MessageBox.Show(err.ToString());
            }
每次走到 response = (FtpWebResponse)request.GetResponse();
就卡住。什么原因呢?????
