c# - 改进代码，添加 Goto 或循环功能

Question

我正在尝试在我的代码中添加 Goto 或类似功能。这个游戏是基于汉谟拉比游戏。我正在尝试删除代码中显示“请重置”的部分并返回问题。

此外，一旦游戏完成，我希望它循环回来并为年份增加价值，但同时也保留原始游戏的价值。

Answer 1

首先，您需要根据职责将程序划分为功能（关注点分离）

class Program
{
    static void Main(string[] args)
    {
        Random rnd = new Random();
        int land = 1000, people = 100, landprice = rnd.Next(17, 26);
        int foodin = 0, landin = 0, landout = 0, seeds = 0;
        int foodcost = 20, food = 2800, totalfoodcost = 0;
        int year = 0;

        for (; year < <break_condition> ; year++)
            StartMyGame(land, foodin, foodcost, year);
     } 
}

此外，您还可以使用goto statement

class Program
{
    static void Main(string[] args)
    {
        Random rnd = new Random();
        int land = 1000, people = 100, landprice = rnd.Next(17, 26);
        int foodin = 0, landin = 0, landout = 0, seeds = 0;
        int foodcost = 20, food = 2800, totalfoodcost = 0;
        int year = 0;

        game_start_pos:

        StartMyGame(land, foodin, foodcost, year++);

        if (!<your_break_condition> )
            goto game_start_pos:
     } 
}
