C# 如何在不创建实例的情况下访问变量？

Question

这就是我想要做的：

public class Worker
{
    public int wage;

    public void pay()
    {
        Economy.money -= this.wage;
        // I want the money(of the economy) to be subtracted by the wage of the worker.
    }
}

public class Economy
{
    public int money;
}

如果能有1个以上的经济就好了

所以我希望经济体（工人所属）的货币减去工人的工资。

我该怎么做？

Answer 1

如果您想要多个经济体，那么您需要一个属性来跟踪每个工人属于哪个经济体。然后您可以使用该参考从正确的经济中减去工资：

public class Worker {

    public Economy InEconomy { get; private set; }
    public int Wage { get; private set; }

    // set the econdomy and wage in the constructor
    public Worker(Economy economy, int wage) {
        this.Wage = wage;
        this.InEconomy = economy;
    }

    public void Pay() {
        InEconomy.money -= this.Wage;
    }
}

public class Economy {
    public int money;
}
