}

如果不需要main函数，则复制下面的

using System;
class Program
{
    public static void start()
    {
        char i1;
        int gens, count;
        count = 0;
        int[] start;
        int[] rules = new int[8];
        i1 = (char)int.Parse(Console.ReadLine());
        gens = int.Parse(Console.ReadLine());
        string str = Console.ReadLine();
        start = new int[str.Length];
        for (int i = 0; i < str.Length; i++)
        {
            if (str[i] == '-')
            {
                start[i] = 0;
            }
            else
            {
                start[i] = 1;
            }
        }
        for (int i = 0; i < 8; i++)
        {
            if ((i1 & 0x80) == 0x80)
            {
                rules[i] = 1;
            }
            else
            {
                rules[i] = 0;
            }
            i1 <<= 1;
        }
        int[] gen = new int[start.Length];
        for (int i = 0; i < gens; i++)
        {
            count++;
