如何在直线/折线c#上查找邻近点

public class Point
{
    public int X { get; set; }
    public int Y { get; set; }
}

public class Line
{
    public List<Point> Points { get; set; }

    public Point FindNearestPoint(Point targetPoint)
    {
        double minDistance = double.MaxValue;
        Point nearestPoint = null;

        foreach (var point in Points)
        {
            double distance = CalculateDistance(point, targetPoint);
            if (distance < minDistance)
            {
                minDistance = distance;
                nearestPoint = point;
            }

    }

    private double CalculateDistance(Point point1, Point point2)
    {
        return Math.Sqrt(Math.Pow(point2.X - point1.X, 2) + Math.Pow(point2.Y - point1.Y, 2));
    }
}

public class Program

        // 创建直线对象并添加点
        Line line = new Line();

            new Point() { X = 1, Y = 1 },
            new Point() { X = 2, Y = 3 },
            new Point() { X = 4, Y = 5 },
            new Point() { X = 6, Y = 7 }
        };

        // 给定目标点
        Point targetPoint = new Point() { X = 3, Y = 4 };

        // 查找最近的点
        Point nearestPoint = line.FindNearestPoint(targetPoint);

        // 输出结果
        Console.WriteLine("最近的点坐标：({0}, {1})", nearestPoint.X, nearestPoint.Y);
    }
