As seen on http://www.dotnetperls.com/redirectstandardoutput:
//
// Setup the process with the ProcessStartInfo class.
//
ProcessStartInfo start = new ProcessStartInfo();
start.FileName = @"C:\7za.exe"; // Specify exe name.
start.UseShellExecute = false;
start.RedirectStandardOutput = true;
//
// Start the process.
//
using (Process process = Process.Start(start))
{
//
// Read in all the text from the process with the StreamReader.
//
using (StreamReader reader = process.StandardOutput)
{
string result = reader.ReadToEnd();
Console.Write(result);
}
}
I've done it myself with Houdini ChessEngine to read PGN files and calculate the board situation with a set of given parameters (WPF application).
