C# - How to call an exe added into project solution

Question

So I added an EXE to my project's solution. The EXE does some stuff and outputs data via stdout. I want to capture the output, but more importantly how do I execute that EXE within my program?

Answer 1

Process p = new Process();
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.FileName = "myExec.exe";
p.Start();

Answer 2

Process.Start. To capture stdout you need to redirect it via ProcessStartInfo - there is an example on MSDN. Make sure also that the exe is marked to be copied to the output directory (bin/release etc).

If you need to read from both stdout and stderr it gets tricky (with a naïve implementation there is a risk of deadlock due to buffering etc)... here's an example using worker threads.
