I'm trying to run CMD from my code. This is the line that I run in my command line, and it works when I run it manually:
C:\Dev\MySite\web\Website\comparison-tool\data\ & node csvToJson.js
This is what I have in my code:
string commandText = String.Format("/C {0}{1} & node csvToJson.js", root, csvToJsonFolder);
Process.Start("CMD.exe", commandText);
commandText evaluates to /C C:\Dev\MySite\web\Website\comparison-tool\data\ & node csvToJson.js
It runs without error, but nothing seems to have happened. The command prompt doesn't open, so I can't see any errors that may have occurred. The command is supposed to result in a file being written to a particular folder, and when I run the command manually the file gets written, but when I run my code the file does not get written.
EDIT: I changed my code to this:
Process process = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.WindowStyle = ProcessWindowStyle.Normal;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = commandText;
startInfo.RedirectStandardOutput = true;
startInfo.UseShellExecute = false;
process.StartInfo = startInfo;
process.Start();
string result = process.StandardOutput.ReadToEnd();
The result is just an empty string. There is no error message or anything.
The problem was in my command text, I forgot "cd". Should have been "/C cd C:\Dev\MySite\web\Website\comparison-tool\data\ & node csvToJson.js"

In c#, run new process cmd and send out command(ex.. ping 127.0.0.1 -t) to cmd
Then redirect Standardoutput to Console..
But in compile I cannot see cmd which is working in pop up window, only know that command is working on hidden state.
How can I show up command prompt like console pop up?? I want to see console window and command prompt at the same time..
If I don't redirect from cmd and only send the command(ex dir) to cmd,
still command prompt window does't showed up and only see console window..
Process proc_cmd = new Process();
ProcessStartInfo startinfo = new ProcessStartInfo();
startinfo.FileName = "cmd.exe";
startinfo.WorkingDirectory = #"c:\";
startinfo.UseShellExecute = false;//to use RedirectStandard~
startinfo.RedirectStandardInput = true;
startinfo.RedirectStandardOutput = true;
startinfo.RedirectStandardError = true;
proc_cmd.EnableRaisingEvents = false;
proc_cmd.StartInfo = startinfo;
proc_cmd.Start();
proc_cmd.StandardInput.Write(#"ping 127.0.0.1 -t" +
Environment.NewLine);
proc_cmd.StandardInput.Close();
type start in command prompt:
start
This will open up a new cmd window.
You may need something like this if you need to view the console on debug:
startInfo.CreateNoWindow = false;
First of all, i searched a lot to avoid asking a duplicate question. If there is one, i will delete this question immediately.
All the solutions on the web are suggesting to use Process.StartInfo like this one
How To: Execute command line in C#, get STD OUT results
I dont want to run a batch file, or an .exe.
I just want to run some commands on cmd like
msg /server:192.168.2.1 console "foo" or ping 192.168.2.1
and return the result if there is one.
How can i do that ?
Those commands are still exe files, you just need to know where they are. For example:
c:\windows\system32\msg.exe /server:192.168.2.1 console "foo"
c:\windows\system32\ping.exe 192.168.2.1
The only proper way to do this is to use Process.Start. This is demonstrated adequately in this question, which is itself a duplicate of two others.
However, as DavidG says, the commands are all exe files and you can run them as such.
Apparently, i found an answer
while (true)
{
Console.WriteLine("Komut giriniz.");
string komut = Console.ReadLine();
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
//startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = "/C" + komut;
startInfo.RedirectStandardOutput = true;
startInfo.UseShellExecute = false;
process.StartInfo = startInfo;
Console.WriteLine(process.Start());
string line = "";
while (!process.StandardOutput.EndOfStream)
{
line = line + System.Environment.NewLine + process.StandardOutput.ReadLine();
// do something with line
}
Console.WriteLine(line);
Console.ReadLine();
}
seems like if you can run cmd.exe with arguments including your command.
thanks for contributing.
I am working on a project of remotely receiving commands from a server, but I am facing a problem when working with the command prompt locally. Once I get it working locally, then I will move to remote communication.
Problem:
I have to completely hide the console, and client must not see any response when the client is working with the command line but it will show a console for a instance and then hide it.
I had to use c# to send a command to cmd.exe and receive the result back in C#. I have done it in one way by setting the StandardOutput... and input to true.
The commands are not working. For example, D: should change the directory to D and it does, but after that, if we use dir to see the directories in D, it does not show the appropriate directories.
Here is my code:
First Method
Process process = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = "/C " + textBoxInputCommand.Text + " >> " + " system";
process.StartInfo = startInfo;
process.Start();
Second Method
ProcessStartInfo procStartInfo = new ProcessStartInfo("cmd", "/c " + textBoxInputCommand.Text);
procStartInfo.WorkingDirectory = #"c:\";
procStartInfo.RedirectStandardOutput = true;
procStartInfo.UseShellExecute = true;
procStartInfo.UseShellExecute = false;
Process proc = new Process();
proc.StartInfo = procStartInfo;
proc.Start();
string result = proc.StandardOutput.ReadToEnd();
richTextBoxCommandOutput.Text += result;
I want the program to run as administrator because the exe it generates does not run commands when it runs from the C drive.
Try not to run the commands by passing them to cmd instead write the commands passed by the client to a.bat file execute the .bat. file from your program this will probably hide your command prompt window.
You can also use process.OutputDataRecieved event handler to do anything with the output.
If you want to execute command using administrator rights you can use runascommand. It is equivalent to the sudo command in Linux. Here is a piece of code may be it will help you
var process = new Process();
var startinfo = new ProcessStartInfo(#"c:\users\Shashwat\Desktop\test.bat");
startinfo.RedirectStandardOutput = true;
startinfo.UseShellExecute = false;
process.StartInfo = startinfo;
process.OutputDataRecieved += DoSomething;
process.Start();
process.BeginOutputReadLine();
process.WaitForExit();
//Event Handler
public void DoSomething(object sener, DataReceivedEventArgs args)
{
//Do something
}
Hope it helps you.
You could hide command prompt window by adding this line of code:
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
or do not create it at all
startInfo.CreateNoWindow = true;
Here can be found a few awarding solutions:
Run Command Prompt Commands
I try to run a process.start() for command in command line, and try to get the output into string or some usefull locaiton. The output will consist of several rows ( like DIR command ). I read how to do it but it doesn' t work for me. It runs but then got into loop and does not stop.See below. any ideas?
ProcessStartInfo myProcessStartInfo = new ProcessStartInfo("cmd.exe",
#" /k dir");
Process myProcess = new Process();
myProcess.StartInfo.RedirectStandardOutput = true;
myProcess.StartInfo.UseShellExecute = false;
myProcess.StartInfo.FileName = "cmd.exe";
myProcess.StartInfo.Arguments = #" /k dir";
myProcess.Start();
string ppp = myProcess.StandardOutput.ReadToEnd();
myProcess.WaitForExit();
Your process will never exit on its own because you're passing the /K flag to cmd.exe which will keep the window open (and hence the process alive) after it runs your command.
/K Carries out the command specified by string but remains
I think what you're looking for here is to use /C which will close the command window after it runs your command.
/C Carries out the command specified by string and then terminates

I have a software which can be executed via command line, and now I want it to be executed directly from my C# app. Sadly, there is no error but I still can't do it. :(
The path of .exe file of the software is C:\program files\mysoftware.exe
The command I would like to input is
cd c:\program files\mysoftwareFolder
enter
mysoftware.exe d:\myfolder\file1.xxx d:\myfolder\file2.xxx -mycommand
enter
exit
The commands above work so well in the actual command prompt, but they just don't work from my C# code.
Here is the code:
Process cmdprocess = new Process();
System.Diagnostics.ProcessStartInfo startinfo = new System.Diagnostics.ProcessStartInfo();
startinfo.FileName = "cmd";
startinfo.WindowStyle = ProcessWindowStyle.Hidden;
startinfo.CreateNoWindow = true;
startinfo.RedirectStandardInput = true;
startinfo.RedirectStandardOutput = true;
startinfo.UseShellExecute = false;
cmdprocess.StartInfo = startinfo;
cmdprocess.Start();
System.IO.StreamReader sr = cmdprocess.StandardOutput;
System.IO.StreamWriter sw = cmdprocess.StandardInput;
sw.WriteLine(#"echo on");
sw.WriteLine(#"c:");
sw.WriteLine(#"cd" +#"program files\mysoftwarefolder");
sw.WriteLine(#"mysoftware.exe" +#"d:\myfolder\file1.xxx" +#"d:\myfolder\file2.xxx" +#"-mycommand");
sw.WriteLine(#"exit");
sw.Close();
sr.Close();
I guess the incorrect parts might be "startinfo.FileName = "cmd";" or the way I typed the command in the code, but I have no idea how to correct them. :(
Please tell me what I did wrong. I appreciate every answer from you! :)))
UPDATE Thank you for your helps! I tried writing the command in batch file, but it only works in debugging mode. (I forgot to tell you guys that I am developing a web service.) When I run my external project which will use this C# service, it won't work. I don't know whether I should add something to my code or not.
help meeeeee pleaseeeee (T___T)
Write these commands in a batch file and execute the batch file.
In batch file:
cd c:\program files\mysoftwareFolder
mysoftware.exe
d:\myfolder\file1.xxx
d:\myfolder\file2.xxx -mycommand
exit
Code:
Process cmdprocess = new Process();
ProcessStartInfo startinfo = new ProcessStartInfo();
startinfo.FileName = "path to batchfile.bat";
startinfo.WindowStyle = ProcessWindowStyle.Hidden;
startinfo.CreateNoWindow = true;
startinfo.RedirectStandardInput = true;
startinfo.RedirectStandardOutput = true;
startinfo.UseShellExecute = false;
cmdprocess.StartInfo = startinfo;
cmdprocess.Start();
Instead of:
startinfo.FileName = "cmd";
Directly use
startinfo.FileName = #"c:\program files\mysoftwarefolder\mysoftware.exe";
Then pass the arguments to the start info as
startinfo.Arguments = #"d:\myfolder\file1.xxx " +#"d:\myfolder\file2.xxx " +#"-mycommand";
So the whole code looks like:
Process p = new Process();
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.FileName = #"c:\program files\mysoftwarefolder\mysoftware.exe";
p.StartInfo.Arguments = #"d:\myfolder\file1.xxx " +#"d:\myfolder\file2.xxx " +#"-mycommand";
p.Start();
string output = p.StandardOutput.ReadToEnd();
p.WaitForExit();
If you need to see output from your program you can simply use the output string.
2 things: I think you have spacing problems and you're not reading the result of these commands. cmd is probably telling you ..."is not recognized as an internal or external command"
If you look at what you're throwing at cmd, it will be:
echo on
c:
cdprogram files\mysoftware folder
mysoftware.exed:\myfolder\file1.xxx
That won't work when you try it in cmd. CMD is almost certainly kicking back error messages at you, but you're never reading from sr so you'll never know it.
I'd add in some spaces and include all the paths in quotes internally like so:
sw.WriteLine(#"echo on");
sw.WriteLine(#"c:");
sw.WriteLine("cd \"program files\\mysoftwarefolder\"");
sw.WriteLine("mysoftware.exe \"d:\\myfolder\\file1.xxx\" d:\\myfolder\\file2.xxx\" -mycommand");
sw.WriteLine(#"exit");
