redirect command to listbox C#

See more:

C#5.0

I have this code that runs
**************************************

Process process = new Process();
process.StartInfo.FileName = "C:\\Program Files\\PAGS1\\pags.exe";
process.StartInfo.Arguments = "status -v";
process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardOutput = true;
process.Start();

// Synchronously read the standard output of the spawned process.
StreamReader reader = process.StandardOutput;
string output = reader.ReadToEnd();

process.WaitForExit();
process.Close();

listBox1.Items.Add(output);
*********************************************************

My problem is that the output is one continuous (single) long line in the listBox.

If ran from command prompt, the output is displayed with 10 lines

I'd like to display the output the same way as if ran from command line. Any help is greatly appreciated
