Make it as a Generic way to Navigate any View controller

    public override void RowSelected(UITableView tableView, NSIndexPath indexPath)
    {
        tableView.DeselectRow(indexPath, false);
        var country = TableItems[indexPath.Row];
        var controller = _navController.TopViewController as GenerateOTPViewController;
        if (controller != null)
        {
            controller.GetCountry(country.CountryName, country.CountryFlag);
            _navController.DismissModalViewController(true);
        }
    }

Hello
How to use instead of GenerateOTPViewController generic way to navigate any viewcontroller using T operator.
