在进行调试时，输入了数据，但在输出结果的时候，窗口突然消失了！但用逐步调试的时候却没有什么问题？求解！！
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Class
{
class Program
{
static void Main(string[] args)
{
int x2 = int.Parse(Console.ReadLine());
int y2 = int.Parse(Console.ReadLine());
Point p1 = new Point();
Point p2 = new Point(x2, y2);
double distance = p1.DistanceTo(p2);
Console.WriteLine(distance);

}
}
}











新建一个类



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

namespace Class
{
class Point
{
private int x;
private int y;

public Point()
{
x = -1;
y = -1;
}
public Point(int z, int h)
{
x = z;
y = h;
}
public double DistanceTo(Point p)
{
int xdis = x - p.x;
int ydis = y - p.y;
return Math.Sqrt(xdis * xdis + ydis * ydis);
}
}
}


[解决办法]
Console.WriteLine(distance);
Console.ReadKey();
