class Program
    {
        static void Main(string[] args)
        {

            string ins = "";
            string[] sparr;
            double[] parr = new double[4];
            do
            {
                Console.Write("输入一组（2个点坐标数据，输入end退出)：");
                ins = Console.ReadLine();

                sparr =  ins.Trim().Replace("  "," ").Split(' ');


                if (ins == "end")
                {
                    break;
                }else if (sparr.Length < 4)
                {
                    Console.WriteLine("输入错误！");

                }else
                {

                    for (int i = 0; i < 4; ++i)
                    {
                        parr[i] = int.Parse(sparr[i]);
                    }
                    Console.WriteLine(" 两点距离：{0}", dis(parr[0], parr[1], parr[2], parr[3]));
                    
                }

                Console.WriteLine("----------------------------------------------");
                


            } while (true);


            Console.Write("按下回车键程序退出...");
            Console.Read();
            
        }

        static double dis(double x1, double y1, double x2, double y2)
        {
            double dx, dy;
            dx = x2 - x1;
            dy = y2 - y1;
            return Math.Sqrt(dx * dx + dy * dy);
        }
    }

需要完善对输入合法性的判断
