Remove items in the first Lixtbox which is added in the second Listbox

Question

I am making a simple ftp app, when I click the browse button, the full path of the files will be added in the first ListBox. When I click on the Send Files button, it will execute and the full path will appear in the second ListBox. What I want to achieve is that, when a particular path is in the second ListBox, it will be removed in the first ListBox.

Here' what I have so far.

  private void button2_Click(object sender, EventArgs e)
    {
         List<string> str = new List<string>();
         OpenFileDialog v1 = new OpenFileDialog();
        v1.Multiselect = true;
         if (v1.ShowDialog() == DialogResult.Cancel)
             return;

         foreach (string s in v1.FileNames)
         {
             ////listBox1.Items.Add(Path.GetFileName(s));
            listTransfer.Items.Add(Path.GetFullPath(s));
             str.Add(s);
         }
    }


    private void button1_Click(object sender, EventArgs e)
    {
        SendFiles();
    }





    private int SendFiles()
    {
        try
        {
            // Setup session options
            SessionOptions sessionOptions = new SessionOptions
            {
                Protocol = Protocol.Ftp,
                HostName = "192.168.1.3",
                UserName = "Admin",
                Password = "foxtrotAlpha",
                PortNumber = 21
               // SshHostKeyFingerprint = "ssh-rsa 2048 xxxxxxxxxxx...="
            };

            using (Session session = new Session())
            {
                // Connect
                session.Open(sessionOptions);

                // Upload files
                TransferOptions transferOptions = new TransferOptions();
                transferOptions.TransferMode = TransferMode.Binary;

                TransferOperationResult transferResult;
                //  transferResult = session.PutFiles(@"d:\upload\*", "/transfer/", false, transferOptions);

                foreach (var listBoxItem in listTransfer.Items)
                {
                    string item = listBoxItem.ToString();
                    string[] result = item.Split(',');
       

                    transferResult = session.PutFiles(@result[0], "/_transfer/", false, transferOptions);
             

                    // Throw on any error

                    transferResult.Check();

                    // Print results
                    foreach (TransferEventArgs transfer in transferResult.Transfers)
                    {
                        lblCompleted.Text = transfer.FileName.ToString();
                        listCompleted.Items.Add(lblCompleted.Text);
                    }
                }
            }
            return 0;
        }
        catch (Exception e )
        {       
            
                MessageBox.Show(e.Message.ToString(),"FTP",MessageBoxButtons.OK,MessageBoxIcon.Error);
                return 1;
        }  
    }

Consider putting

listTransfer.Remove(listBoxItem);

somewhere suitable, like above //print results..
