在C＃中使用CMD.exe时的“多步”命令

Question

I'm trying to use "multi-step" command in ac# script, for example the command "net user usrname *" contains 3 steps to enter a password and then validate, i don't know if it is possible to send extra arguments while the Process is running

My code:

Process p = new Process();
p.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
p.StartInfo.CreateNoWindow = true;
p.StartInfo.FileName = "cmd.exe";
p.StartInfo.Arguments = "/C " + command;
p.StartInfo.WorkingDirectory = startupFolder;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true;
p.StartInfo.UseShellExecute = false;
p.Start();
string output = p.StandardOutput.ReadToEnd();
string error = p.StandardError.ReadToEnd();

You would concatenate each command with "&". For example, "cmd /k echo Test 1 & echo test 2".

Edit:

I created a remote control/remote admin solution a while back that uses this same technique to allow you to run batch and PowerShell scripts against remote computers via the web portal. As shown in the below screenshot, it works.

The C# that executes the command can be found here: https://github.com/Jay-Rad/InstaTech_Client/blob/master/InstaTech_Service/Socket.cs#L614

if (cmdProcess == null || cmdProcess.HasExited)
{
    var psi2 = new ProcessStartInfo("cmd.exe", "/k " + command);
    psi2.RedirectStandardOutput = true;
    psi2.RedirectStandardInput = true;
    psi2.RedirectStandardError = true;
    psi2.UseShellExecute = false;
    psi2.WorkingDirectory = Path.GetPathRoot(Environment.SystemDirectory);

    cmdProcess = new Process();
    cmdProcess.StartInfo = psi2;
    cmdProcess.EnableRaisingEvents = true;
    cmdProcess.OutputDataReceived += async (object sender, DataReceivedEventArgs args) =>
    {
        jsonMessage.Status = "ok";
        jsonMessage.Output = args.Data;
        await SocketSend(jsonMessage);

    };
    cmdProcess.ErrorDataReceived += async (object sender, DataReceivedEventArgs args) =>
    {
        jsonMessage.Status = "ok";
        jsonMessage.Output = args.Data;
        await SocketSend(jsonMessage);
    };
    cmdProcess.Start();
    cmdProcess.BeginOutputReadLine();
    cmdProcess.BeginErrorReadLine();
}
else
{
    cmdProcess.StandardInput.WriteLine(command);
}
