C#.Net写的Juliet集程序

选了一门物理学的课，老师留的作业，试着用C#写了下。分享下程序代码和大家交流一下。

代码：

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;

 

namespace WindowsFormsApplication2

{

    public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

        // 复数类

        public class Complex

        {

            //默认构造函数

 

            public Complex()

                : this(0, 0)

            {

            }

 

            // 只有实部的构造函数

 

            public Complex(double real)

                : this(real, 0)

            {

            }

 

            // 由实部和虚部构造

 

            public Complex(double real, double image)

            }
