Run Command Prompt Commands

this is all you have to do run shell commands from C#

string strCmdText;
strCmdText= "/C copy /b Image1.jpg + Archive.rar Image2.jpg";
System.Diagnostics.Process.Start("CMD.exe",strCmdText);

EDIT:

This is to hide the cmd window.

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 copy /b Image1.jpg + Archive.rar Image2.jpg";
process.StartInfo = startInfo;
process.Start();

EDIT 2:

It is important that the argument begins with /C, otherwise it won't work. As @scott-ferguson said: /C carries out the command specified by the string and then terminates.

Tried RameshVel's solution but I could not pass arguments in my console application. If anyone experiences the same problem here is a solution:

using System.Diagnostics;

Process cmd = new Process();
cmd.StartInfo.FileName = "cmd.exe";
cmd.StartInfo.RedirectStandardInput = true;
cmd.StartInfo.RedirectStandardOutput = true;
cmd.StartInfo.CreateNoWindow = true;
cmd.StartInfo.UseShellExecute = false;
cmd.Start();

cmd.StandardInput.WriteLine("echo Oscar");
cmd.StandardInput.Flush();
cmd.StandardInput.Close();
cmd.WaitForExit();
Console.WriteLine(cmd.StandardOutput.ReadToEnd());

var proc1 = new ProcessStartInfo();
string anyCommand; 
proc1.UseShellExecute = true;

proc1.WorkingDirectory = @"C:\Windows\System32";

proc1.FileName = @"C:\Windows\System32\cmd.exe";
proc1.Verb = "runas";
proc1.Arguments = "/c "+anyCommand;
proc1.WindowStyle = ProcessWindowStyle.Hidden;
Process.Start(proc1);
