ProcessStartInfo hanging on “WaitForExit”? Why?

Question

I have the following code:

info = new System.Diagnostics.ProcessStartInfo(\"TheProgram.exe\", String.Join(\" \", args));
info.CreateNoWindow = true;
info.Win         


        

Answer 1

Workaround I ended up using to avoid all the complexity:

var outputFile = Path.GetTempFileName();
info = new System.Diagnostics.ProcessStartInfo("TheProgram.exe", String.Join(" ", args) + " > " + outputFile + " 2>&1");
info.CreateNoWindow = true;
info.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
info.UseShellExecute = false;
System.Diagnostics.Process p = System.Diagnostics.Process.Start(info);
p.WaitForExit();
Console.WriteLine(File.ReadAllText(outputFile)); //need the StandardOutput contents

So I create a temp file, redirect both the output and error to it by using > outputfile > 2>&1 and then just read the file after the process has finished.

The other solutions are fine for scenarios where you want to do other stuff with the output, but for simple stuff this avoids a lot of complexity.
