Upload files to ftp through proxy

[pritesh3173]

I am working on windows application with c#.net .
I am using FTPwebreuqest class for upload file on ftp.it works fine when there is no proxy between application and internet. but it doesn't work in proxy.

FtpWebRequest reqFTP;
if i use reqFTP.Proxy=new webproxy("proxyservername",21);
then it will display error message "FTP command doen't support in HTTP proxy".

my code is like this




FtpWebRequest reqFTP;
reqFTP = (FtpWebRequest)FtpWebRequest.Create("ftp://uri");

reqFTP.Credentials = new NetworkCredential("username", "pwd");

reqFTP.KeepAlive = false;

reqFTP.Method = WebRequestMethods.Ftp.UploadFile;
reqFTP.UseBinary = true;
reqFTP.UsePassive = true;
int buffLength = 2048;

byte[] buff = new byte[buffLength];
int contentLen;

FileStream fs = fileInf.OpenRead();

Stream strm = reqFTP.GetRequestStream();

contentLen = fs.Read(buff, 0, buffLength);

while (contentLen != 0)
{
strm.Write(buff, 0, contentLen);
contentLen = fs.Read(buff, 0, buffLength);
prbUpload.Value += contentLen;
}

strm.Close();
fs.Close();


Any one help me about proxy settings in FTPwebrequest
