Using FTP File as Input Provider

The sample C# code below demonstrates how to fetch a CSV file from a remote FTP server (using third-party library) and loading its content as input provider for the Data List command. Sample agent is attached to this article.

CODE

using System;
using System.Collections.Generic;
using System.Data;
using System.IO;
using Sequentum.ContentGrabber.Api;
public class Script
{
   //See help for a definition of DataProviderArguments.
   public static CustomDataStorage ProvideData(DataProviderArguments args)
   {
     var server = "ftp://ftp.dlptest.com/";
     var port = 21;
     var username = "dlpuser@dlptest.com";
     var password = "fLDScD4Ynth0p4OJ6bW6qCxjh";
     var remoteFilePath = "testfolder/testInput.csv";
 
     var cds = new CustomDataStorage();
     var tempFile = Path.GetTempFileName();
     FluentFTP.FtpClient client = null;
     try
     {
       using (client = new FluentFTP.FtpClient(server, port, username, password))
       {
         // Connect to the server
         client.Connect();
         // Download file
         if (client.DownloadFile(tempFile, remoteFilePath, true, FluentFTP.FtpVerify.None, null))
         {
           // Load downloaded csv file.
           cds = args.ScriptUtilities.LoadCsvFile(tempFile, true);
         }
         else
         {
           throw new Exception("Failed to download file: " + remoteFilePath);
         }
       }
     }
     catch (Exception ex)
     {
       throw ex;
     }
     finally
     {
       // Delete temporary file
       if (File.Exists(tempFile)) File.Delete(tempFile);
       if (client != null) client.Disconnect();
     }
 
     return cds;
   }
}

Required third-party library: FluentFTP. Download the DLL into your Agent's "Assembly" folder, and add "FluentFTP.dll" in your Agent's Assembly References. The DLL is already added and set up in the attached sample agent.
