ProgramOutputHook

Demonstrates how one can easily hook to a program's output and display it in a console (or GUI app)

The most interesting part :

        private static void StartProcess(string programToListenTo, string programArgument = null)
        {
            var process = new Process();
            var procStartInfo = new ProcessStartInfo(programToListenTo, programArgument)
            {
                UseShellExecute = false, // has to be false for redirecting output
                RedirectStandardOutput = true,
                RedirectStandardError = true,
                StandardOutputEncoding = Encoding.UTF8
            };

            process.StartInfo = procStartInfo;
            process.EnableRaisingEvents = true;
            process.OutputDataReceived += (s, e) => Console.WriteLine(e.Data);
            process.ErrorDataReceived += (s, e) => Console.WriteLine(e.Data);

            process.Start();

            process.BeginOutputReadLine();
            process.BeginErrorReadLine();

            Console.WriteLine($"Program {programToListenTo} started" +
                              $"{(string.IsNullOrEmpty(programArgument) ? "." : $"with arguments : '{programArgument}'")}");

            process.WaitForExit();
        }
