Remove all directory permissions & set new permissions using C#

Question

I want to remove previously set directory permissions to a folder & set new permissions as per requirement.

I have referred this link Remove All Directory Permissions

but once i removed all permission it never allows me to set new rules.

my code

 DirectoryInfo myDirectoryInfo = new DirectoryInfo("D:\\Shared\\Testing");
                DirectorySecurity myDirectorySecurity = myDirectoryInfo.GetAccessControl();
                string User = System.Environment.UserDomainName + "\\" + Convert.ToString(dt_UserDetails.Rows[i]["AD_NAME"]);

                AuthorizationRuleCollection rules = myDirectorySecurity.GetAccessRules(true, true, typeof(System.Security.Principal.NTAccount));

                myDirectorySecurity.SetAccessRuleProtection(true, false);

                if (Convert.ToInt16(dt_UserDetails.Rows[i]["ACCESS_CONTROL_TYPE"]) == 1)
                {
                    new FileSystemAccessRule(User, FileSystemRights.ChangePermissions, AccessControlType.Allow);

                }
                else if (Convert.ToInt16(dt_UserDetails.Rows[i]["ACCESS_CONTROL_TYPE"]) == 0)
                {
                    new FileSystemAccessRule(User, FileSystemRights.ChangePermissions, AccessControlType.Deny);                    
                }

                myDirectoryInfo.SetAccessControl(myDirectorySecurity);

Is there any solution for this?

@EhsanSajjad i have tried that code already. but if i remove all permissions and try to set new then I'm unable to do it — user2148124, Jan 18 '16 at 10:53
Well, if you remove all permissions then the code itself no longer has permission to change permissions... so this behaviour is correct. You have to leave the permission that allows your code to alter the other permissions intact while it's running. — Neil Hewitt, Jan 18 '16 at 11:29
