小弟這學期開始學C# 這是某一次的作業但是我想了很久想不出來QQ 寫一支 console 程式將梯形、平行四邊形、矩形與正方形實體化，並印出：梯形的高、平行邊之和（即上底+下底）、面積；平行四邊形的底、高、面積；矩形的長、寬、面積；正方形的邊長、面積。 Quadrilateral public class Point { public double X { get; private set; } public double Y { get; private set; } public Point( double xCoordinate, double yCoordinate ) { X = xCoordinate; Y = yCoordinate; } public override string ToString() { return string.Format( "( {0:F1}, {1:F1} )", X, Y ); } } public class Quadrilateral { public Point Point1 { get; private set; } public Point Point2 { get; private set; } public Point Point3 { get; private set; } public Point Point4 { get; private set; } public Quadrilateral( double x1, double y1, double x2, double y2, double x3, double y3, double x4, double y4 ) { Point1 = new Point( x1, y1 ); Point2 = new Point( x2, y2 ); Point3 = new Point( x3, y3 ); Point4 = new Point( x4, y4 ); } public override string ToString() { return string.Format( "Coordinates of Quadrilateral are:\n{0}", GetCoordinatesAsString() ); } public string GetCoordinatesAsString() { return string.Format( "{0}, {1}, {2}, {3}\n", Point1, Point2, Point3, Point4 ); } } Subclasses public class Trapezoid : Quadrilateral { public double GetHeight() {} public double GetArea() {} public double GetSumOfTwoSides() {} } public class Parallelogram : Trapezoid { public double GetWidth() {} } public class Rectangle : Parallelogram {} public class Square : Parallelogram {} 可以幫解的話感激不盡 --
