Start a process in the same console

Question

Can I start a process (using C# Process.Start()) in the same console as the calling program? This way no new window will be created and standard input/output/er

Answer 1

You could try redirecting the output of this process and then printing it on the calling process console:

public class Program
{
    static void Main()
    {
        var psi = new ProcessStartInfo
        {
            FileName = @"c:\windows\system32\netstat.exe",
            Arguments = "-n",
            RedirectStandardOutput = true,
            UseShellExecute = false
        };
        var process = Process.Start(psi);
        while (!process.HasExited)
        {
            Thread.Sleep(100);
        }

        Console.WriteLine(process.StandardOutput.ReadToEnd());
    }
}

Alternative approach using the Exited event and a wait handle:

static void Main()
{
    using (Process p = new Process())
    {
        p.StartInfo = new ProcessStartInfo
        {
            FileName = @"netstat.exe",
            Arguments = "-n",                                        
            RedirectStandardOutput = true,
            UseShellExecute = false                    
        };
        p.EnableRaisingEvents = true;
        using (ManualResetEvent mre = new ManualResetEvent(false))
        {
            p.Exited += (s, e) => mre.Set();
            p.Start();
            mre.WaitOne();
        }

        Console.WriteLine(p.StandardOutput.ReadToEnd());
    }           
}
