设计一个点类，线段类继承点类
实现几个方法就行
编好的话加分，二十几行左右就可以了

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

namespace Line
{
class Program
{
static void Main(string[] args)
{
point A = new point(0,0);
A.write();
point B = new point(1,1);
B.write();
line line = new line(A, B);
line.writeLine();
}
}

/// <summary>
/// 点类
/// </summary>
public class point
{
private double x;
private double y;
public point()
{

}
public point(double X,double Y)
{
x = X;
y = Y;
}

public double X
{
set { x = value ; }
get { return x; }
}
