req = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://**.**.**.**/shiyan.txt"));
req.Credentials = new NetworkCredential(ftpUserName, ftpPwd);
req.KeepAlive = false;
req.Method = WebRequestMethods.Ftp.Rename; ///更改这行
req.UseBinary = true;
req.RenameTo = "ftp://**.**.**.**/rename_or_move_to/shiyan.txt"; ///加入这行

using (FtpWebResponse Response = (FtpWebResponse)req.GetResponse())
{
long size = Response.ContentLength;
using (Stream datastream = Response.GetResponseStream())
{
using (StreamReader sr = new StreamReader(datastream))
{
sr.ReadToEnd();
sr.Close();

datastream.Close();
}
Response.Close();
}
