FTP Upload ftpWebRequest Proxy

FTP command is not supported when using HTTP proxy

 

 

In the article below I will cover 2 topics

 

1.       C# & Windows Command-Line FTP Upload with No Proxy Server

 

2.       C# & Windows Command-Line FTP Upload with Proxy Server

 

Not covered here: Secure FTP / SFTP

 

Sample Attributes:

·         UploadFilePath = “\\servername\folder\file.name”

·         Proxy Server = “ftp://proxy.server/”

·         FTP Target Server = ftp.target.com

·         FTP User = “User”

·         FTP Password = “Password”

with No Proxy Server

·         Windows Command-Line

> ftp ftp.target.com

> ftp User: User

> ftp Password: Password

> ftp put \\servername\folder\file.name

> ftp dir

          (result: file.name listed)

> ftp del file.name

> ftp dir

          (result: file.name deleted)

> ftp quit

 

·         C#

 

//-----------------

//Start FTP via _TargetFtpProxy

//-----------------

string relPath = Path.GetFileName(\\servername\folder\file.name);

 

//result: relPath = “file.name”

 

FtpWebRequest ftpWebRequest = (FtpWebRequest)WebRequest.Create("ftp.target.com/file.name);

ftpWebRequest.Method = WebRequestMethods.Ftp.UploadFile;

 

//-----------------

//user - password

//-----------------

ftpWebRequest.Credentials = new NetworkCredential("user, "password");

 

//-----------------

// set proxy = null!

//-----------------

ftpWebRequest.Proxy = null;

 

//-----------------

// Copy the contents of the file to the request stream.

//-----------------

StreamReader sourceStream = new StreamReader(“\\servername\folder\file.name”);

 

byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());

sourceStream.Close();

ftpWebRequest.ContentLength = fileContents.Length;

 

 

//-----------------

// transer the stream stream.

//-----------------

Stream requestStream = ftpWebRequest.GetRequestStream();

requestStream.Write(fileContents, 0, fileContents.Length);

requestStream.Close();

 

//-----------------

// Look at the response results

//-----------------

FtpWebResponse response = (FtpWebResponse)ftpWebRequest.GetResponse();

 

Console.WriteLine("Upload File Complete, status {0}", response.StatusDescription);

 

with Proxy Server

·         Windows Command-Line

> ftp proxy.server

> ftp User: User@ftp.target.com
