What I'd like to Do
I'd like to create a simple C# application that creates a Process object (the application's child process) that runs cmd.exe and, inside that shell, execute the command echo "Hello World!" (or whatever arbitrary string I specified before compiling the application). The C# application, when built and ran, creates and leave the shell in this state:
Attempts
I've searched stackoverflow and MSDN for examples but it's difficult to find the right options to set for Process, ProcessStartInfo. In particular, I tried:
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApp1
{
class Program
{
static void Main(string[] args)
{
/*
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = "echo helloworld!";
string strCmdText;
process.StartInfo = startInfo;
process.Start();
*/
var proc = new Process
{
StartInfo = new ProcessStartInfo
{
FileName = @"cmd.exe", // iexplorer.exe opened up ie!
Arguments = "",
UseShellExecute = false,
RedirectStandardOutput = true,
CreateNoWindow = false,
WorkingDirectory = @"C:\Users\mtran\Desktop\ConsoleApp1",
WindowStyle = ProcessWindowStyle.Normal
}
};
proc.Start();
}
}
}
but either second cmd window (for the child process) never appears (if I set RedirectStandardOutput = false)or the output of from the child process gets written to the parent's cmd window.
