This should get you started:
public class Program
{
public static void Main(string[] args)
{
var proc = new Process
{
StartInfo = new ProcessStartInfo
{
FileName = "cmd.exe",
CreateNoWindow = true,
UseShellExecute = false,
RedirectStandardInput = true,
RedirectStandardOutput = true,
RedirectStandardError = true
}
};
proc.Start();
new Thread(() => ReadOutputThread(proc.StandardOutput)).Start();
new Thread(() => ReadOutputThread(proc.StandardError)).Start();
while (true)
{
Console.Write(">> ");
var line = Console.ReadLine();
proc.StandardInput.WriteLine(line);
}
}
private static void ReadOutputThread(StreamReader streamReader)
{
while (true)
{
var line = streamReader.ReadLine();
Console.WriteLine(line);
}
}
}
The basics are:
- open cmd.exe process and capture all three streams (in, out, err)
- pass input from outside in
- read output and transfer to your own output.
The "Redirect" options are important - otherwise you can't use the process' respective streams.
The code above is very basic, but you can improve on it.
