I used the below code. In my case, I had a semi colon de-limited string as the parameter which is read from web.config. You may change the below code easily if you are passing a List.

public class ActiveDirectoryGroup
{
    public static bool IsInAnyRole(string adRoles)
    {
        return adRoles.Split(Convert.ToChar(";")).Any(role => !string.IsNullOrEmpty(role.Trim()) && HttpContext.Current.User.IsInRole(role.Trim()));
        //If list is passed use below
        //return listParameter.Any(role => !string.IsNullOrEmpty(role.Trim()) && HttpContext.Current.User.IsInRole(role.Trim()));
    }
}

In web.config:

I used it like below in my page load:

if (ActiveDirectoryGroup.IsInAnyRole(ConfigurationManager.AppSettings["ADGroup"]))
{
  //do something
}
