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

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?

From stackoverflow
  • 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.

  • Process p = new Process();
    p.StartInfo.UseShellExecute = false;
    p.StartInfo.RedirectStandardOutput = true;
    p.StartInfo.FileName = "myExec.exe";
    p.Start();
    
    : this answer worked. thanks!
    David Rogers : although the relative file path will only work if the Current Working Directory hasn't changed...
