第七周学习内容

实现一下测试代码功能

      //测试代码1：二维坐标点类
        Point pPoint = new Point(45, 56);
        Console.WriteLine(pPoint.X);// 应该输出45
        Console.WriteLine(pPoint.Y);//应该输出56
        Point pPoint2 = new Point();
        Console.WriteLine(pPoint2.X);//输出默认值10；
        Console.WriteLine(pPoint2.Y);//输出默认值20；
        
       // 测试代码2：矩形类
        Rectangle pRectangle = new Rectangle(5.5, 4.0);
        Console.WriteLine(pRectangle.L);// 输出矩形的长 = 5.5；
        Console.WriteLine(pRectangle.W);// 输出矩形的宽 = 4.0；
        Console.WriteLine(pRectangle.GetArea());// 输出矩形的面积 22.0；
        Console.WriteLine(pRectangle.GetPerimeter());// 输出矩形的周长 19.0
        
        //// 测试代码3: 文本读取类,用于读取txt文本对象，需在D盘目录下建立一个名称为test的文本文档。
        //// 文本内容为 hello CSharp.文本读取的相关方法需百度。
        //TxtReader pReader = new TxtReader("d://test.txt");//构造函数传入的是文件的路径
        //string pContent = pReader.ReadContent();// 通过读取内容的函数能够读取其所有内容
        //Console.WriteLine(pContent); // 输出的内容应该为hello CSharp
        
         // 测试代码4：文本创建类，用于创建txt文本对象。相关内容自行百度学习。
        string pFileSavePath = "D://txtWriter.txt";
        TxtWriter pWriter = new TxtWriter(pFileSavePath);// 构造函数传入需要创建的txt文件的路径
        pWriter.WriteContent("Hello CSharp");  // WriteContent方法写入文本
        TxtReader pReader = new TxtReader(pFileSavePath);
        string pWriteContent = pReader.ReadContent();
        Console.WriteLine(pWriteContent);// 输出的内容应该为Hello CSharp;
        
         //// 测试代码5：多边形类，继承与多态练习，多态与继承的概念可以自行百度
        Polygon pPolygon1 = new RectangleClass(4, 5);// 构造函数传入长和宽
        Polygon pPolygon2 = new SquareClass(5);     // 构造函数传入边长
        Console.WriteLine(pPolygon1.GetArea());     // 应该输出20
        Console.WriteLine(pPolygon2.GetArea());     // 应该输出25

测试1：

class Point
{
    private int x;
            public int X
    {
        get
        {
            return x;
        }
        set
        {
            x = value;
        }
    }
     private int y;
    public int Y
    {
        get
        {
            return y;
        }
        set
        {
            y = value;
        }
    }
    public Point(int x = 10, int y = 20)
    {
        this.x = x;
        this.y = y;
    }
}
