Question

Is there any way to run command prompt commands from within a C# application? If so how would I do the following:

if you want to run the command in async mode - and print the results. you can you this class:

    public static class ExecuteCmd
{
    /// <summary>
    /// Executes a shell command synchronously.
    /// </summary>
    /// <param name="command">string command</param>
    /// <returns>string, as output of the command.</returns>
    public static void ExecuteCommandSync(object command)
    {
        try
        {
            // create the ProcessStartInfo using "cmd" as the program to be run, and "/c " as the parameters.
            // Incidentally, /c tells cmd that we want it to execute the command that follows, and then exit.
            System.Diagnostics.ProcessStartInfo procStartInfo = new System.Diagnostics.ProcessStartInfo("cmd", "/c " + command);
            // The following commands are needed to redirect the standard output. 
            //This means that it will be redirected to the Process.StandardOutput StreamReader.
            procStartInfo.RedirectStandardOutput =  true;
            procStartInfo.UseShellExecute = false;
            // Do not create the black window.
            procStartInfo.CreateNoWindow = true;
            // Now we create a process, assign its ProcessStartInfo and start it
            System.Diagnostics.Process proc = new System.Diagnostics.Process();
            proc.StartInfo = procStartInfo;
            proc.Start();

            // Get the output into a string
            string result = proc.StandardOutput.ReadToEnd();

            // Display the command output.
            Console.WriteLine(result);
        }
        catch (Exception objException)
        {
            // Log the exception
            Console.WriteLine("ExecuteCommandSync failed" + objException.Message);
        }
    }

    /// <summary>
    /// Execute the command Asynchronously.
    /// </summary>
    /// <param name="command">string command.</param>
    public static void ExecuteCommandAsync(string command)
    {
        try
        {
            //Asynchronously start the Thread to process the Execute command request.
            Thread objThread = new Thread(new ParameterizedThreadStart(ExecuteCommandSync));
            //Make the thread as background thread.
            objThread.IsBackground = true;
            //Set the Priority of the thread.
            objThread.Priority = ThreadPriority.AboveNormal;
            //Start the thread.
            objThread.Start(command);
        }
        catch (ThreadStartException )
        {
            // Log the exception
        }
        catch (ThreadAbortException )
        {
            // Log the exception
        }
        catch (Exception )
        {
            // Log the exception
        }
    }

}

Answer 2

You can achieve this by using the following method (as mentioned in other answers):

strCmdText = "'/C some command";
Process.Start("CMD.exe", strCmdText);

When I tried the methods listed above I found that my custom command did not work using the syntax of some of the answers above.

I found out more complex commands need to be encapsulated in quotes to work:

string strCmdText;
strCmdText = "'/C cd " + path + " && composer update && composer install -o'";
Process.Start("CMD.exe", strCmdText);
