FtpWebRequest

Since version 4 and in version 2009 you may use the .NET framework inside Dynamics AX. The FtpWebRequest class in the System.Net namespace handles FTP communication like upload, download, delete files and retrieve a list of files in a directory, etc.

Upload File

<xpp> static void uploadTestFile(Args _args) {

   System.Object ftpo;
   System.Object ftpResponse;
   System.Net.FtpWebRequest request;
   System.IO.StreamReader reader;
   System.IO.Stream requestStream;
   System.Byte[] bytes;
   System.Net.NetworkCredential credential;
   System.String xmlContent;
   System.Text.Encoding utf8;

   System.Net.FtpWebResponse response;
   ;

   // Read file
   reader = new System.IO.StreamReader("C:/test.xml");
   utf8 = System.Text.Encoding::get_UTF8();
   bytes = utf8.GetBytes( reader.ReadToEnd() );
   reader.Close();

   // little workaround to get around the casting in .NET
   ftpo = System.Net.WebRequest::Create("ftp://ftp.company.com/dir/test.xml");
   request = ftpo;
   
   credential = new System.Net.NetworkCredential("user","password");
   request.set_Credentials(credential);
   request.set_ContentLength(bytes.get_Length());
   request.set_Method("STOR");

   // "Bypass" a HTTP Proxy (FTP transfer through a proxy causes an exception)
   // request.set_Proxy( System.Net.GlobalProxySelection::GetEmptyWebProxy() );

   requestStream = request.GetRequestStream();
   requestStream.Write(bytes,0,bytes.get_Length());
   requestStream.Close();
   
   ftpResponse = request.GetResponse();
   response = ftpResponse;
   info(response.get_StatusDescription());

} </xpp>

Read from FTP

<xpp> static void readFromFTP(Args _args) {

   System.Object ftpo;
   System.Net.FtpWebRequest request;
   System.IO.StreamReader reader;
   System.Net.NetworkCredential credential;
   System.Net.FtpWebResponse response;
   System.String text;
   ;

   ftpo = System.Net.WebRequest::Create("ftp://ftpserver.com/dir/myfile.txt");
   request = ftpo;
   credential = new System.Net.NetworkCredential("user","password");
   request.set_Credentials(credential);

   response = request.GetResponse();
   reader = new System.IO.StreamReader(response.GetResponseStream());
   text = reader.ReadToEnd();
   info(text);

} </xpp>
