C#求矩形类面积并比较using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication1 { class Rectangle { private double m, n; public Rectangle(double x, double y) { x=m ; y = n; } public static void Area() { Console.WriteLine("area={0}", x * y); } static void Main() { Retangle.a = new Rectangle(4.5, 7.6); a.Area(); Retangle.b = new Rectangle(3.9, 9.2); b.Area(); if (a > b) Console.WriteLine("a>b"); else Console.WriteLine("a<=b"); Console.Read(); } } } 为什么通不过

Answer 1

using System; using System.Collections.Generic; using System.Text; namespace ConsoleApplication1 { class Rectangle { private double m, n; public Rectangle(double x, double y) { this.m = x; this.n = y; } public double Area() { Console.WriteLine("area={0}", m * n); return m * n; } static void Main() { Rectangle a = new Rectangle(4.5, 7.6); a.Area(); Rectangle b = new Rectangle(3.9, 9.2); b.Area(); if (a.Area() > b.Area()) Console.WriteLine("a>b"); else Console.WriteLine("a<=b"); Console.Read(); } } } 给你修改了 你看是不是这样的结果 打好基础吧 你的函数都没有写好
