 上述代码中所用到的类  将数据转化成x、y的点。

public class DataInfo
    {
        private DataInfo()
        {

        }

        public DataInfo(double x, double y, double inCurvature = 0)

        }
        public double X { get; set; }
        public double Y { get; set; }
        public double curvature { get; set; }

        public override bool Equals(object obj)
        {
