C#面向对象习题创建Box盒子类

定义一个带构造方法的Box盒子类。要求可以设置形状，可计算体积和表面积

初学者，作笔记发，代码写的一般。望各位大佬提出批评和建议。

using System.Reflection.Metadata;namespace _3.2
{internal class Program{static void Main(string[] args){Console.WriteLine("长方体输入0,圆柱体输入1");int shp = Convert.ToInt32(Console.ReadLine());if (shp == 0){Console.WriteLine("输入长：");int len = Convert.ToInt32(Console.ReadLine());Console.WriteLine("输入宽：");int wid = Convert.ToInt32(Console.ReadLine());Console.WriteLine("输入高：");int hei = Convert.ToInt32(Console.ReadLine());Box box = new Box(len, wid, hei);int area = box.areaCuboid();int V = box.volumeCuboid();Console.WriteLine("长方体面积是{0}体积是{1}", area, V);}else if (shp == 1) {Console.WriteLine("输入高：");int hei = Convert.ToInt32(Console.ReadLine());Console.WriteLine("输入半径：");int r = Convert.ToInt32(Console.ReadLine());Box box = new Box(r,hei);int area = box.areaCylinder();int V = box.volumeCylinder();Console.WriteLine("圆柱体面积是{0}体积是{1}", area, V);}Console.ReadLine();}}public class Box{public int length, width, height, R;public Box(int len, int wid, int hei)   //构造函数1长方体盒子{length = len;width = wid;height = hei;}public Box(int r,int hei)   //构造函数2圆柱体盒子{R = r;height = hei;}public int areaCuboid() //方法：计算长方体面积{int area = 2*(length*width + width*height + length*height);return area;}public int volumeCuboid() //方法：计算长方体体积{int volume = length*width*height;return volume;}public int areaCylinder()   //方法：计算圆柱体表面积{int area = 2*(int)Math.PI*R*R + 2*(int)Math.PI*R*height;return area;}public int volumeCylinder()     //方法：计算圆柱体体积{int volume = (int)Math.PI * R * R * height;return volume;}}
