Hi,
I need to check text file from other computer system file that is sharing on network, and copy some file from network system to local.

I use this code

private string strDestination = @"C:\Program Files\SASystem\SASystem";
private string strSource = @"\\192.192.11.250\ver\IIversion\_New";

delete local file

private void DeleteFilesFromDirectory(string directoryPath)
       {
           DirectoryInfo d = new DirectoryInfo(directoryPath);
           foreach (FileInfo fi in d.GetFiles())
           {
               fi.Delete();
           }
           foreach (DirectoryInfo di in d.GetDirectories())
           {
               DeleteFilesFromDirectory(di.FullName);
               di.Delete();
           }
       }

check txt file

//Check Current Version
            string Current_Version = AssemblyName.GetAssemblyName(strDestination + @"\SASystem.exe").Version.ToString();
            //Check New Version
            StreamReader wr = File.OpenText(@"\\192.192.11.250\ver\IIversion\New_Version.txt");
            string New_version = wr.ReadToEnd();
            wr.Close();
            int Current = Convert.ToInt32(Current_Version.Replace(".", ""));
            int New = Convert.ToInt32(New_version.Replace(".", ""));
            if (New > Current)
            {
                if (MessageBox.Show("New version is available on server, Do you want to Upgrade current Version? ", "New Version", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
                {
                    this.Opacity = 100;
                }
                else
                {
                    //System.Diagnostics.Process.Start(strDestination + @"\SASystem.exe");
                    Application.ExitThread();
                }
            }
            else
            {
                System.Diagnostics.Process.Start(strDestination + @"\SASystem.exe");
                Application.ExitThread();
            }

copy file

private void copyDirectory(string strSource, string strDestination)
       {
           bUpdat.Text = "Skip";
           // searches current directory and sub directory
           int fCount = Directory.GetFiles(strSource, "*.*", SearchOption.AllDirectories).Length;
           // MessageBox.Show(fCount+"");
           progressBar1.Maximum = fCount;

           if (!Directory.Exists(strDestination))
           {
               Directory.CreateDirectory(strDestination);
           }
           DirectoryInfo dirInfo = new DirectoryInfo(strSource);
           FileInfo[] files = dirInfo.GetFiles();
           foreach (FileInfo tempfile in files)
           {
               Application.DoEvents();
               if (bUpdat.Text == "Skip")
               {
                   progressBar1.PerformStep();
                   tempfile.CopyTo(Path.Combine(strDestination, tempfile.Name));
               }
               Application.DoEvents();
           }
           DirectoryInfo[] dirctororys = dirInfo.GetDirectories();
           foreach (DirectoryInfo tempdir in dirctororys)
           {
               if (bUpdat.Text == "Skip")
               {
                   copyDirectory(Path.Combine(strSource, tempdir.Name), Path.Combine(strDestination, tempdir.Name));
               }
               Application.DoEvents();
           }

           progressBar1.Value = 0;
           bUpdat.Text = "Upgrade ";

       }

Is there anyone help me to modify this code? thanks for attention!
