Hi,
I have to upload files on a ftp server through a ftp proxy with
Dotnet.
I have a 'System.InvalidOperationException' with this message : "The
requested FTP command is not supported when using HTTP proxy". Is
there a solution to use a FTP proxy and not a HTTP proxy ?

Thanks
Marc

My code (in CLI/C++, but the same in C#) :

   // Get the object used to communicate with the server.
   FtpWebRequest^ request = (FtpWebRequest^)WebRequest::Create("ftp://
xxx.xxx.com"); // Uri of ftp server
   request->Method = WebRequestMethods::Ftp::UploadFile;

   // FTP Proxy
   request->Proxy = gcnew WebProxy("ftpProxyHostname", 21);

   request->Credentials = gcnew
NetworkCredential("ftpServerUser","password");

   // Copy the contents of the file to the request stream.
   StreamReader^ sourceStream = gcnew StreamReader(exportDirectory +
zipName);
   array<Byte>^ fileContents = Encoding::UTF8->GetBytes(sourceStream-

   sourceStream->Close();
   request->ContentLength = fileContents->Length;

   Stream^ requestStream = request->GetRequestStream();
   requestStream->Write(fileContents, 0, fileContents->Length);
   requestStream->Close();

   FtpWebResponse^ response = (FtpWebResponse^)request->GetResponse();
