Executing bat file using bcp to copy datatable to text file

Can you give me the logic to use the SqlBulkCopy to copy data table from SQL SERVER Datatable to text file.

this works below, but once I execute the bat file I have no way of knowing when its down, what I am doing is copying all data to text files, then afterwards, delete from the database. So is there a way to know if the bat file has finished executing berfore deleting from the database.

      process.StartInfo.UseShellExecute = false;
              
      process.StartInfo.FileName = Directory.GetCurrentDirectory.;

      if (File.Exists(RapidViewClient.Properties.Settings.Default.ExamplePath))
      {
           process.StartInfo.CreateNoWindow = false;
           process.Start();
      }
