Compiling and Running Code

1. Save the following code in file 'cmdexe.cs'. The FileName and Arguments makes the program run with it's process hidden in background:

class Cmdexec {
        static void Main(){
                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 echo 'fire' > C:\\Users\\<username>\\Desktop\\cs-file";
                process.StartInfo = startInfo;
                process.Start();
        }
}

2. Compile the code to an executable format (.exe):

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\csc.exe .\cmdexe.cs
