Code Conversion

Hi,

Can any advise how to convert below to Visual Cobol?

using System;

using System.IO;

using System.Net;

using System.Net.Security;

using System.Security.Cryptography.X509Certificates;

namespace ConnectToFtpDemo

{

    class Program

    {

        static void Main(string[] args)

        {

            try

            {

                FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp:///testFileUpload.txt"); 

                request.Method = WebRequestMethods.Ftp.UploadFile; 

                request.Credentials = new NetworkCredential("Username", "Password");

                request.EnableSsl = true;

                ServicePointManager.ServerCertificateValidationCallback = ServicePointManager_ServerCertificateValidationCallback;

                long bytesSent = 0;

                using (Stream requestStream = request.GetRequestStream())

                using (FileStream uploadFileStream = File.OpenRead("C:\\Test\\test.txt"))

                {

                    uploadFileStream.CopyTo(requestStream);

                    bytesSent = uploadFileStream.Position;

                }

            }

            catch (Exception ex)

            {

                Console.WriteLine(ex);

            }

            Console.ReadLine();

        }

        private static bool ServicePointManager_ServerCertificateValidationCallback(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors)

        {

            //TODO: Logic to determine if certificate sent by server on connection is valid if it is return to true otherwise return false

            return true;

            //Type type = null;

            //var publicKey = certificate.GetPublicKeyString();

            //// Check public key if matche

            //type = certificate.GetType();

            //var p = type.GetProperty("Thumbprint");

            //var thumbPrint = p.GetValue(certificate)?.ToString();

        }

    }

}
