Redirecting C++ console output to C#

Question

I'm trying to get the output of the C++ console to the C# Windows Form application, the problem I'm having is the output of the C++ exe is displayed in the C# console only after the C++ exe is terminated. Is there anyway to get the exe output to C# console in real time while running the C++ exe (as in without having to terminate the exe)? Here is how I tried,

Process p = new Process();
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.FileName = "C:\\path\\ABC.exe";
p.Start();
string output = p.StandardOutput.ReadToEnd();
Console.WriteLine(output);

Thanks,

Use OutputDataReceived event:

Process p = new Process();
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.FileName = "C:\\path\\ABC.exe";
p.OutputDataReceived += (s, e) => Console.WriteLine(e.Data);
p.Start();
p.BeginOutputReadLine();

Ah, my answer was exactly the same but I was too slow. – Oleg Kolosov Feb 04 '12 at 08:11
Thanks Max, it works fine with OutputDataReceived. Yet performance is quite slow when getting the output to c# console, but that's ok i guess. – Anshu Feb 04 '12 at 10:29
