A more generic way of doing it is to take any IComparable objects.

    public static bool Compare(string op, T left, T right) where T : IComparable {
        switch (op) {
            case "<": return left.CompareTo(right) < 0;
            case ">": return left.CompareTo(right) > 0;
            case "<=": return left.CompareTo(right) <= 0;
            case ">=": return left.CompareTo(right) >= 0;
            case "==": return left.Equals(right);
            case "!=": return !left.Equals(right);
            default: throw new ArgumentException("Invalid comparison operator: {0}", op);
        }
    }
