Question

I have a command-line process I would like to automate and capture in C#.

At the command line, I type:

nslookup 

This launches a shell which gives me a > prompt. At the prompt, I then type:

ls -a mydomain.local 

This returns a list of local CNAMEs from my primary DNS server and the physical machines they are attached to.

What I would like to do is automate this process from C#. If this were a simple command, I would just use Process.StartInfo.RedirectStandardOutput = true, but the requirement of a second step is tripping me up.

Answer 1

ProcessStartInfo si = new ProcessStartInfo('nslookup'); si.RedirectStandardInput = true; si.RedirectStandardOutput = true; Process nslookup = new Process(si); nslookup.Start(); nslookup.StandardInput.WriteLine('ls -a mydomain.local'); nslookup.StandardInput.Flush(); // use nslookup.StandardOutput stream to read the result.
