C # program calls CMD to execute command

In the Windows environment, the command-line program for Cmd.exe, is a 32-bit command-line program, Microsoft Windows system based on the Windows command interpreter, similar to Microsoft's DOS operating system. Enter some commands, Cmd.exe can be executed, such as input shutdown-s will shut down in 30 seconds. In short, it is very useful. Open method: Start-All Programs-attachments or start-find-Input: Cmd/cmd.exe enter. It can also execute a bat file.

The following is an introduction to executing commands using C # programs called CMD:

Code:

1 usingSystem;2 usingSystem.Collections.Generic;3 usingSystem.Linq;4 usingSystem.Text;5 usingSystem.Threading.Tasks;6 usingSystem.Diagnostics;7 8 namespaceCmddemo9 {Ten     class Program One     { A         Static voidMain (string[] args) -         { -Console.WriteLine ("Please enter the command you want to execute:"); the             stringStrinput =console.readline (); -Process p =NewProcess (); -             //set up the application to start -p.StartInfo.FileName ="Cmd.exe"; +             //whether to start with the operating system shell -P.startinfo.useshellexecute =false; +             //accept input from the calling program AP.startinfo.redirectstandardinput =true; at             //Output Information -P.startinfo.redirectstandardoutput =true; -             //Output Error -P.startinfo.redirectstandarderror =true; -             //do not show program window -P.startinfo.createnowindow =true; in             //Start the program - P.start (); to  +             //send input information to the CMD window -P.standardinput.writeline (strinput+"&exit"); the  *P.standardinput.autoflush=true; $ Panax Notoginseng              //Get output Information -             stringStrouput =p.standardoutput.readtoend (); the             //wait for the program to finish executing the exit process + p.waitforexit (); A p.close (); the  + Console.WriteLine (strouput); -  $ Console.readkey (); $         } -     } -}
