Question

In my console application, I need to execute a series of commands:

D:
cd d:\datafeeds
grp -encrypt -myfile.xls

This set of commands actually encrypt a file using a tool (gpg).
How will I do it ?

Answer 1

Create a batch file that contains your commands.
Then use Process.Start and ProcessStartInfo class to execute your batch.

  ProcessStartInfo psi = new ProcessStartInfo(@"d:\datafeeds\yourbatch.cmd");
  psi.WindowStyle = ProcessWindowStyle.Minimized;
  psi.WorkingDirectory = @"d:\datafeeds";
  Process.Start(psi);

ProcessStartInfo contains other useful properties See MSDN docs
Process and ProcessStartInfo require an using System.Diagnostics;

In this scenario (when you need to run command line tools) I prefer to use the batch approach instead of coding everything through the ProcessStartInfo properties. It will be more flexible when you have to change something and you have not the code available.
