C#偏移垂直于给定线段的点

using System;

public class Program
{
    public static void Main()
    {
        // 定义线段的起始点和终点坐标
        double startX = 0;
        double startY = 0;
        double endX = 5;
        double endY = 5;

        // 定义偏移距离
        double offsetDistance = 2;

        // 计算线段的方向向量
        double directionX = endX - startX;
        double directionY = endY - startY;

        // 计算垂直于线段的向量
        double perpendicularX = -directionY;
        double perpendicularY = directionX;

        // 计算偏移垂直于线段的点的坐标
        double offsetX = startX + offsetDistance * perpendicularX;
        double offsetY = startY + offsetDistance * perpendicularY;

        // 输出偏移垂直于线段的点的坐标
        Console.WriteLine("偏移垂直于给定线段的点的坐标为：({0}, {1})", offsetX, offsetY);
    }
