FtpWebRequest请求=(FtpWebRequest)FtpWebRequest.Create("ftp://www.itsthe1.com/profiles/nuwan/sample.txt");

request.Method = WebRequestMethods.Ftp.UploadFile;
request.Credentials = new NetworkCredential(用户名，密码);
request.UsePassive = true;
request.UseBinary = true;
request.KeepAlive = false;

//加载文件
FileStream流= File.OpenRead(@"C:\ sample.txt");
byte []缓冲区=新的byte [stream.Length];

stream.Read(buffer，0，buffer.Length);
stream.Close();

//上传文件
流reqStream = request.GetRequestStream();
reqStream.Write(buffer，0，buffer.Length);
