Answer 1

double CalaGirth(); //接口成员方法(默认抽象公共的) } class Rectangle1 : IShape //实现图形接口的矩形类{public double Length //长度属性{get{return length;}set{if (value < 0){throw new Exception("矩形长度不能为负数！");}else{length = value;}}}public double Width //宽度属性{get{return width;}set{if (value < 0){throw new Exception("矩形宽度不能为负数！");}else{width = value;}}}public Rectangle1() //默认构造函数{ }public Rectangle1(double length, double width) //默认的构造函数{Length = length; Width = width;}public override double CalaArea() //重写继承基类的抽象方法{return length * width;}public override double CalaGirth() //重写继承基类的抽象方法{return 2 * (length + width);}private double length; //私有的长度实例字段 private double width; //私有的宽度实例字段 } sealed class Circle1 : IShape //实现图形接口的圆类{public double Radius //半径属性{get{return radius;}set{if (value < 0){throw new Exception("圆半径不能为负数！");}else{radius = value;}}}public Circle1() //默认的搞函数{ }public Circle1(double radius) //默认的构造函数{Radius = radius;}public sealed override double CalaArea() //重写继承基类的抽象方法{return Math.PI * radius * radius;}public sealed override double CalaGirth() //重写继承基类的抽象方法{return Math.PI * 2 * radius;}private double radius; //私有的半径实例字段}}错误1 “WpfApplication1.Rectangle1.CalaArea()”: 没有找到适合的方法来重写 错误2 “WpfApplication1.Rectangle1.CalaGirth()”: 没有找到适合的方法来重写错误3 “WpfApplication1.Circle1.CalaArea()”: 没有找到适合的方法来重写 错误4 “WpfApplication1.Circle1.CalaGirth()”: 没有找到适合的方法来重写
