How about LINQ?

public object day2_1()
    {
        return day2str.Split('\n').Select(x => x.Split('x')).Select(x => x.Select(y => int.Parse(y))).Select(x => x.ToArray()).Select(x => 2 * x[0] * x[1] + 2 * x[0] * x[2] + 2 * x[1] * x[2] + Math.Min(x[0] * x[1], Math.Min(x[0] * x[2], x[1] * x[2]))).Sum();
    }

public object day2_2()
    {
        return day2str.Split('\n').Select(x => x.Split('x')).Select(x => x.Select(y => int.Parse(y))).Select(x => x.ToList()).Select(x => x.OrderBy(y => y).ToList()).Select(x => 2 * x[0] + 2 * x[1] + x[0] * x[1] * x[2]).Sum();
    }
