    }


    public static bool IsLessThenOrEqualTo(this T value, T other)
         where T : System.IComparable
    {
        var result = value.CompareTo(other);
        return result == -1 || result == 0;
    }


    public static bool IsGreaterThenOrEqualTo(this T value, T other)
         where T : System.IComparable
    {
        var result = value.CompareTo(other);
        return result == 1 || result == 0;
    }
