Use the StandardOutput stream:

process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardOutput = true;

// ...
// read from process.StandardOutput

Alternatively, rather than reading from StandardOutput directly, you can call BeginOutputReadLine passing a callback that will tell you whenever a new line is outputted.
