Using system;using system.collections.generic;using system.linq;using system.web;///<summary>///chouxiang Summary description///</summary> abstract class Wuyu {public class Operation {private double number            A = 0;            Private double numberb = 0;                Public double Numbera {get {return numbera;}            set {Numbera = value;}                } public double Numberb {get {return numberb;}            set {Numberb = value;}    }} public abstract double Xiaole (double A, double b);        } class Jiafa:wuyu {public override double Xiaole (double A, double b) {return a + B; }} class Jianfa:wuyu {public override double Xiaole (double A, double b) {Retu        RN A-B;            }} class Chengfa:wuyu {public override double Xiaole (double A, double b) {return a * b; }} class Chufa:wuyu {public override double Xiaole (double A, double b) {return A/        b }    }
