Run Command Prompt Commands

You can do this using CliWrap in one line:

var result = await Cli.Wrap("cmd")
    .WithArguments("copy /b Image1.jpg + Archive.rar Image2.jpg")
    .ExecuteBufferedAsync();

var stdOut = result.StandardOutput;

if you want to keep the cmd window open or want to use it in winform/wpf then use it like this

    string strCmdText;
//For Testing
    strCmdText= "/K ipconfig";

 System.Diagnostics.Process.Start("CMD.exe",strCmdText);

/K

Will keep the cmd window open

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
        }
    }

}

This can also be done by P/Invoking the C standard library's system function.

using System.Runtime.InteropServices;

[DllImport("msvcrt.dll")]
public static extern int system(string format);

system("copy Test.txt Test2.txt");

Output:

      1 file(s) copied.

I have the following method, which I use to run the command prompt commands from C#

In first parameter pass the command you want to run

public static string RunCommand(string arguments, bool readOutput)
{
    var output = string.Empty;
    try
    {
        var startInfo = new ProcessStartInfo
        {
            Verb = "runas",
            FileName = "cmd.exe",
            Arguments = "/C "+arguments,
            WindowStyle = ProcessWindowStyle.Hidden,
            UseShellExecute = false,
            CreateNoWindow = true,
            RedirectStandardOutput = true,
            RedirectStandardError = false
        };

        var proc = Process.Start(startInfo);

        if (readOutput)
        {
            output = proc.StandardOutput.ReadToEnd(); 
        }

        proc.WaitForExit(60000);

        return output;
    }
    catch (Exception)
    {
        return output;
    }
}

you can use simply write the code in a .bat format extension ,the code of the batch file :

c:/ copy /b Image1.jpg + Archive.rar Image2.jpg

use this c# code :

Process.Start("file_name.bat")

You can use RunProcessAsTask pacakge and run your process async and easily like this:

var processResults = await ProcessEx.RunAsync("git.exe", "pull");
//get process result
foreach (var output in processResults.StandardOutput)
{
   Console.WriteLine("Output line: " + output);
}

This may be a bit of a read so im sorry in advance. And this is my tried and tested way of doing this, there may be a simpler way but this is from me throwing code at a wall and seeing what stuck

If it can be done with a batch file then the maybe over complicated work around is have c# write a .bat file and run it. If you want user input you could place the input into a variable and have c# write it into the file. it will take trial and error with this way because its like controlling a puppet with another puppet.

here is an example, In this case the function is for a push button in windows forum app that clears the print queue.

using System.IO;
using System;

   public static void ClearPrintQueue()
    {

        //this is the path the document or in our case batch file will be placed
        string docPath =
         Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
        //this is the path process.start usues
        string path1 = docPath + "\\Test.bat";

        // these are the batch commands
        // remember its "", the comma separates the lines
        string[] lines =
        {
            "@echo off",
            "net stop spooler",
            "del %systemroot%\\System32\\spool\\Printers\\* /Q",
            "net start spooler",
            //this deletes the file
            "del \"%~f0\"" //do not put a comma on the last line
        };

        //this writes the string to the file
        using (StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "test.bat")))
        {
            //This writes the file line by line
            foreach (string line in lines)
                outputFile.WriteLine(line);
        }
        System.Diagnostics.Process.Start(path1);

    }

IF you want user input then you could try something like this.

This is for setting the computer IP as static but asking the user what the IP, gateway, and dns server is.

you will need this for it to work

public static void SetIPStatic()
    {
//These open pop up boxes which ask for user input
        string STATIC = Microsoft.VisualBasic.Interaction.InputBox("Whats the static IP?", "", "", 100, 100);
        string SUBNET = Microsoft.VisualBasic.Interaction.InputBox("Whats the Subnet?(Press enter for default)", "255.255.255.0", "", 100, 100);
        string DEFAULTGATEWAY = Microsoft.VisualBasic.Interaction.InputBox("Whats the Default gateway?", "", "", 100, 100);
        string DNS = Microsoft.VisualBasic.Interaction.InputBox("Whats the DNS server IP?(Input required, 8.8.4.4 has already been set as secondary)", "", "", 100, 100);



        //this is the path the document or in our case batch file will be placed
        string docPath =
         Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
        //this is the path process.start usues
        string path1 = docPath + "\\Test.bat";

        // these are the batch commands
        // remember its "", the comma separates the lines
        string[] lines =
        {
            "SETLOCAL EnableDelayedExpansion",
            "SET adapterName=",
            "FOR /F \"tokens=* delims=:\" %%a IN ('IPCONFIG ^| FIND /I \"ETHERNET ADAPTER\"') DO (",
            "SET adapterName=%%a",
            "REM Removes \"Ethernet adapter\" from the front of the adapter name",
            "SET adapterName=!adapterName:~17!",
            "REM Removes the colon from the end of the adapter name",
            "SET adapterName=!adapterName:~0,-1!",
//the variables that were set before are used here
            "netsh interface ipv4 set address name=\"!adapterName!\" static " + STATIC + " " + STATIC + " " + DEFAULTGATEWAY,
            "netsh interface ipv4 set dns name=\"!adapterName!\" static " + DNS + " primary",
            "netsh interface ipv4 add dns name=\"!adapterName!\" 8.8.4.4 index=2",
            ")",
            "ipconfig /flushdns",
            "ipconfig /registerdns",
            ":EOF",
            "DEL \"%~f0\"",
            ""
        };

        //this writes the string to the file
        using (StreamWriter outputFile = new StreamWriter(Path.Combine(docPath, "test.bat")))
        {
            //This writes the file line by line
            foreach (string line in lines)
                outputFile.WriteLine(line);
        }
        System.Diagnostics.Process.Start(path1);

    }

Like I said. It may be a little overcomplicated but it never fails unless I write the batch commands wrong.
