如何在.NET中将double值舍入到选定的小数位数？

using System;

class Program
{
    static void Main()
    {
        double value = 123.456789;
        int decimalPlaces = 2;

        double roundedValue = RoundToSpecifiedDecimalPlaces(value, decimalPlaces);

        Console.WriteLine($"Original value: {value}");
        Console.WriteLine($"Rounded value: {roundedValue}");
    }

    static double RoundToSpecifiedDecimalPlaces(double value, int decimalPlaces)
    {
        double factor = Math.Pow(10, decimalPlaces);
        return Math.Round(value * factor) / factor;
    }
}
