今天是暑假过后，上课的一天，一个暑假在迷茫中和发呆中度过没有对所学的东西进行任何复习

。所以在上课中对老师所复习的以前内容都快记不清啦！所以要在今后奋斗

。对今天上课的练习进行一下总结。首先创建Person类并添加相应的字段与方法和构造函数，并且有num字段能够记录这个类生生成了多少个具体的对象。using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace 练习
{
    class Person
    {
        public string name;
        public int age;
        public char sex;
        private static int count;

        public static int GetCircleCount()
        {
            return count;
        }

        public Person()
        {
        }

        public Person(string xm)
        {
            name = xm;
            count++;
        }
        public Person(int nl)
        {
            age = nl;
            count++;
        }
        public Person(char xb)
        {
            sex = xb;
            count++;
        }
    }
}

首先是定义的person类并对对象进行定义好各个输出

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace 练习
{
    class Program
    {
        static void Main(string[] args)
        {
            Person p = new Person("Tom");
            Console.WriteLine(p.name);
            Console.WriteLine(Person.GetCircleCount());

            Person p1 = new Person(20);
            Console.WriteLine(p1.age);
            Console.WriteLine(Person.GetCircleCount());

            Person p2 = new Person('男');

            Console.WriteLine(p2.sex);
            Console.WriteLine(Person.GetCircleCount());

            Console.ReadKey();

｝

｝对对象进行具体描述在控制台输出

2分别使用面向过程的方法和面向对象的方法，完成如下命题：求两点之间的距离。这是分别用面向对象和过程进行输出

class Program
{
static void Main(string[] args)
{
int x1 = -1;
int y1 = -1;
int x2 = int.Parse(Console.ReadLine());
int y2 = int.Parse(Console.ReadLine());
int xdiff = x2 - x1;
int ydiff = y2 - y1;
double distance = Math.Sqrt(xdiff * xdiff + ydiff * ydiff);
Console.WriteLine(distance);这是面向过程代码完全可见

//int x1 = int.Parse(Console.ReadLine());
//int y2 = int.Parse(Console.ReadLine());
//Point d1 = new Point();
//Point d2 = new Point(x1, y2);
//double distance = d1.Distance(d2);
//double distance2 = d2.Distance(d1);
//Console.WriteLine(distance);
//Console.WriteLine(distance2);
Console.ReadKey();
}
}
private int x;
private int y;

public Point()
{
x = -1;
y = -1;
}
public Point(int x1, int y2)
{
x = x1;
y = y2;
}
public double Distance(Point d)
{
int xdiff = x - d.x;
int ydiff = y - d.x;
return Math.Sqrt(xdiff * xdiff + ydiff * ydiff);
}
