Programmatically assigned network service access to folder using c#

Question

I have an installer that runs some c# code. I want the c# code to give 'full control' to a folder for the 'network service' account. Is this possible?

I see some examples online with connecting to a domain. But the network service is not on a domain it's a local account and I just wanted to know how to do it in c#?

Cheers

DirectoryInfo dirInfo = new DirectoryInfo("C:\\TestDir2");
DirectorySecurity dirSecurity = dirInfo.GetAccessControl();

dirSecurity.AddAccessRule(new FileSystemAccessRule("ASPNET", FileSystemRights.Write|FileSystemRights.DeleteSubdirectoriesAndFiles, InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit, PropagationFlags.InheritOnly, AccessControlType.Allow));

dirInfo.SetAccessControl(dirSecurity);
