Console commands

    I have tested it now, but i don't receive the full output iether. Check this example at GotDotNet: netstat in C#.

  • Joe H

    Use my first code sample and when the process is idle and you received all information just kill the process and it stops running. Then code code will continue.

    I never tested the code and just wrote it out the head.

    thanks but i want this:

    " i want to execute cmd commands but do not show cmd... "

    You need to read until the process has exited:


    try
    {
    ProcessStartInfo info = new ProcessStartInfo("cmd.exe","netstat -n");
    info.RedirectStandardInput = true;
    info.RedirectStandardOutput = true;
    info.CreateNoWindow = true;
    info.WindowStyle = ProcessWindowStyle.Hidden;
    info.UseShellExecute = false;
    Process process = Process.Start(info);

    using( StreamReader reader = process.StandardOutput )
    {
    while( !process.HasExited )
    {
    string line = reader.ReadLine();
    Debug.WriteLine( line, "Console output" );
    }
    }
    }
    catch (Exception ex)
    {
    Console.WriteLine(ex.ToString());
    }


    Or when you use netstat only once:

    try
    {
    ProcessStartInfo info = new ProcessStartInfo("cmd.exe","netstat -n");
    info.RedirectStandardInput = true;
    info.RedirectStandardOutput = true;
    info.CreateNoWindow = true;
    info.WindowStyle = ProcessWindowStyle.Hidden;
    info.UseShellExecute = false;
    Process process = Process.Start(info);
    process.WaitForExit();

    using( StreamReader reader = process.StandardOutput )
    {
    string fullOuput = reader.ReadToEnd();
    Debug.WriteLine( fullOuput, "Console output" );
    }
    }
    catch (Exception ex)
    {
    Console.WriteLine(ex.ToString());
    }

    Check the Process and the ProcessStartInfo classes.

    thanks,, this is my code:


    try
                {
                    ProcessStartInfo info = new ProcessStartInfo("cmd.exe","netstat -n");
                    info.RedirectStandardInput = true;
                    info.RedirectStandardOutput = true;
                    info.CreateNoWindow = true;
                    info.WindowStyle = ProcessWindowStyle.Hidden;
                    info.UseShellExecute = false;
                    Process process = Process.Start(info);
                    System.IO.StreamReader rdr = process.StandardOutput;
                    int count = rdr.Read();
                    char[] text = new char[count];
                    rdr.Read(text, 0, text.Length);
                    rdr.Close();
                    string x = null;
                    foreach (char c in text)
                    {
                        x = x + c;
                    }
                    Console.WriteLine(x);
                }
                catch (Exception ex)
                {
                    Console.WriteLine(ex.ToString());
                }
     


    but my result is this:

    Microsoft Windows XP [Version 5.1.2600]... <--- this allways shows up when u open the cmd,,, how can i get the result of the command netstat - n or maybe dir =(

    ProcessStartInfo info = new ProcessStartInfo( @"cmd" );
    info.RedirectStandardInput = true;
    info.RedirectStandardOutput = true;
    info.CreateNoWindow = true;
    info.WindowStyle = ProcessWindowStyle.Hidden;
    Process process = Process.Start( info );


    Use the StandardInput stream property to send command and StandardOutput stream to read the responses.
