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.

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.

See Console.SetIn() (and SetOut) and Process.StandardOutput
