Just execute this code
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Series
{
    class Program
    {
        static void Main(string[] args)
        {
            System.IO.Directory.CreateDirectory(@"c:\Program Files\SubFolder");
            System.Console.ReadKey();
        }
    }
}

You'll want to modify the manifest that gets embedded in the program. This works on Visual Studio 2008 and higher: Project + Add New Item, select "Application Manifest File". Change the element to:

<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

The user gets the UAC prompt when they start the program. Use wisely; their patience can wear out quickly.

The C:\program files folder is protected (by design) in Vista and Windows 7 (and Windows Server 2008 / 2008 R2) - normal user accounts do not have any permission to create directories in there - it's a system folder.
Either you need to run as admin - then you have permission to create directories even in protected system folders - or you create the directories elsewhere and not inside a protected system folder. The second option would be the recommended and preferred option.

hi surya,

the systems which have configured for admin accesss to perticular folders as for your example, program Files, Windows, etc.
If you are not an administrator or your permission does not have access than you can't create any file or folders over there. if you know the password for the administrator than you can create it in a different way.

Hi surya,

If you are not loged on administrator you can't create the new directory in the program files. try to create in some other path.

Directory.CreateDirectory(path);

using System.Security.AccessControl;
using System.Security.Principal;

var dir = System.Environment.ExpandEnvironmentVariables("%systemdrive%\\Program Files");

if (!Directory.Exists(dir))
{
System.IO.Directory.CreateDirectory(dir);
}

You should have the admin rights to create the folder under c:\program files\.

Are you trying to deploy something, then try the Setup project.
