System.Diagnostics.ProcessStartInfo

It is possible to redirect input/output using the ProcessStartInfo class.
You can use this class for better control over the process that is started.
In this example we are running a command prompt and getting a list of all the directories and then sending this information to a text file.

System.Diagnostics.ProcessStartInfo start_info; 
start_info = ProcessStartInfo(); 
start_info.FileName = "cmd.exe"; 
start_info.Arguments = @"/C dir *"; 
start_info.CreateNoWindow = true; 
start_info.RedirectStandardOutput = true; 
start_info.UseShellExecute = false; 

System.Diagnostics.Process? process_files; 
process_files = Process.Start(start_info); 

if (process_files != null) 
{ 
   System.IO.StreamReader reader = process_files.StandardOutput; 
   string results = reader.ReadToEnd(); 
   System.Console.WriteLine(results);
