Question

这是一堂课为什么在MySales上获取和设置，以及theUnits使我的程序无法正常工作？香港专业教育学院试图评论它，删除它，什么都行不通。我无法弄清楚它为什么不起作用

    public class salesinvoice

        private double Netmoney;

        private double StateValue;
        private double LocalValue;
        private double stateTax = 0.0745;

        public double theUnits

        }
        public void NetSales()
        {
            Netmoney = theUnits * MySales;
        }

        public void StateTax()
        {
            StateValue = Netmoney * stateTax;
        }

        public void LocalTax()
        {
            LocalValue = Netmoney * localTax;
        }

        public void GrossSales()
        {
            Newmoney = Netmoney + StateValue + LocalValue;
        }
    }
}

如果您希望C＃为您生成访问者，请使用

public double theUnits { get; set;}

如果你想自己处理它们，你需要一个像这样的私人副本：

private double _theUnits;
public double theUnits { 
    get { return this._theUnits; } 
    set { this._theUnits = value; }
}

在我的课程中获取并设置让我的程序中断？
