Spawn process, redirect StdOut

I'm trying to spawn cmd.exe and write its output to a file. Here's the code:

Code:

m_File=File.CreateText("output.txt");
	
proc=new Process();
proc.StartInfo.FileName="cmd.exe";
proc.StartInfo.UseShellExecute=false;
proc.StartInfo.RedirectStandardOutput=true;
proc.Start();
m_Out=proc.StandardOutput;

Thread thd=new Thread(new ThreadStart(ReadStdOut));

proc.WaitForExit();
.
.
.

public void ReadStdOut()
{
	for (;;)
	{
		string Output=m_Out.ReadLine();
		if (null==Output)
			break;
               m_File.WriteLine(Output);				
	}
	proc.WaitForExit();
}

I can see an empty console flash quickly on the screen, but the process seems to end straight away, and nothing is written to the file. Shouldn't it write the prompt to the file, and then wait for something from STDIN?

If there is an easier way to do this I would love to know.

Code:

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.IO;
using System.Text;

namespace RedirectStandardOutput
{
    class Program
    {
        static void Main(string[] args)
        {
            Process cmdProcess = new Process();
            StreamWriter outStream = new StreamWriter("output.txt");

            cmdProcess.StartInfo.FileName = "cmd.exe";
            cmdProcess.StartInfo.UseShellExecute = false;
            cmdProcess.StartInfo.RedirectStandardOutput = true;

            cmdProcess.Start();

            outStream.Write(cmdProcess.StandardOutput.ReadToEnd());
            
            cmdProcess.WaitForExit();

            outStream.Close();
        }
    }
}

Since stdout is being redirected, if you run this you'll see a blank console (cmd.exe), but if you feed it something like "dir", the output will end up in output.txt.

Does that help?

That works nicely, thanks. I'm going to be expanding upon this basic functionality though, so I will likely have more questions.
