Execute .c file to generate .exe from c# Form Application

I'm trying to use gcc compiler to get Output exe file. When I perform this from file explorer and cmd manually it work as expected but through Code no output is generated. I'm new to this C# and any help would be really appreciated.
Process process = new Process()
ProcessStartInfo startInfo = new ProcessStartInfo();
process.StartInfo.WorkingDirectory = #"C:\Users\abc\Documents\Visual Studio 2017\Projects\CodeJam_FormApplication\CodeJam_FormApplication";
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = "/C gcc Test.c -o Output.exe";
process.StartInfo = startInfo;
process.Start();

How to execute repeated dos commands using c#

I am using below codes with c# for executing doss command in the comment line i executed notepad and in the comment line i tried to execute excel but nobody running if i comment any one from notepad or excel then it executes. I want to execute dos commands one by one weather previous command finish its process or not.
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 notepad";
startInfo.Arguments = "/C excel";
process.StartInfo = startInfo;
process.Start();

By setting the Arguments property twice you are replacing "/C notepad" with "/C excel". The process is launching cmd.exe and passing only "/C excel" to it as an argument.
I suspect that cmd.exe cannot find the Excel exe when it's passed as a "/C" argument. This would explain why you don't see anything executing. You may need to specify the complete path to Excel.
If you want to execute both Notepad and Excel, you will need to launch them one after another by first setting one argument then calling Start for each application.
Something like this:
System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
process.StartInfo = startInfo;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = "/C notepad";
process.Start();
startInfo.Arguments = "/C {Insert the full path to Excel exe}excel";
process.Start();
Alternatively, you can launch both applications launched from the process rather then as parameters to cmd.exe. Process itself is cmd.exe. This will allow the OS to have a better chance of finding the application using the Windows Path variables
Something like this:
System.Diagnostics.ProcessStartInfo startInfo = new ProcessStartInfo();
System.Diagnostics.Process process = new System.Diagnostics.Process();
process.StartInfo = startInfo;
startInfo.FileName = "notepad";
process.Start();
startInfo.FileName = "excel";
process.Start();

Working with the command prompt in C#

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;

Execute a Batch File From C#

I have a small problem. Okay let's say from my C# console application I want to run a batch file that will take an argument. The string variable at the stop of my C# application will be the string argument to pass to the batch file. How would I go about doing it?
Here is my code so far my C# console program:
//String argument to pass to the batch file
string message = "Hello World";
System.Diagnostics.Process process = new System.Diagnostics.Process();
//startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
startInfo.FileName = "Greetings.bat";
startInfo.Arguments = "/C " + message;
process.StartInfo = startInfo;
process.Start();
My Batch File
CLS
#ECHO OFF
ECHO %1

You can give argument like this.
ProcessStartInfo psi = new ProcessStartInfo(filePath);
psi.WindowStyle = ProcessWindowStyle.Hidden;
psi.Arguments = "value1";

Executing command-prompt command in C#

:)
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");
