如何在C#中将IPv4地址转换为整数？

using System;
using System.Net;
using System.Numerics;

class Program
{
    static void Main()
    {
        string ipAddress = "192.168.1.1";
        IPAddress address = IPAddress.Parse(ipAddress);
        byte[] bytes = address.GetAddressBytes();
        BigInteger result = 0;

        for (int i = 0; i< bytes.Length; i++)
        {
            result = result << 8;
            result += bytes[i];
        }

        Console.WriteLine($"IPv4地址 {ipAddress} 对应的整数为：{result}");
    }
}
