Question

currently I have a process that runs, but it requires the user to enter

y <return>
<return>

The code I am using is as follows

ProcessStartInfo psi = new ProcessStartInfo();
string exepath = Directory.GetParent(System.Reflection.Assembly.GetExecutingAssembly().Location).ToString();
Process proc = new Process();
psi.FileName = exepath + @"\lib\dnaml";
psi.RedirectStandardInput = true;
psi.Arguments = "y\r \r";
psi.UserShellExecute = true;
proc.StartInfo = psi;
proc.Start();
proc.WaitForExit();

I want to hard type these inputs in. Any suggestions? Thanks

The Arguments property corresponds to the command-line, not data entered via standard input.

The RedirectStandardInput property is part of the puzzle. Then you also need to write to the stream connected to the StandardInput property. Also note that standard input redirection is incompatible with ShellExecute, it needs CreateProcess to work. So set UseShellExecute = false.

psi.RedirectStandardInput = true;
psi.UseShellExecute = false;
proc.StartInfo = psi;
proc.Start();
proc.StandardInput.WriteLine("y ");
proc.StandardInput.WriteLine();
proc.WaitForExit();
