C＃如何在不创建实例的情况下访问变量？

Question

这是我想做的事：

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; 
} 

我想，如果我能有超过1个经济。

所以我想把工人的工资减去经济（工人所属的）的钱。

我该怎么做？

Answer 1

如果你想要多个经济体，那么你需要一个能够追踪每个工人属于哪个经济体的财产。然后，您可以使用该参考来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; 
}
