从C#中的角度计算圆周长上的点？

using System;

class CirclePoints
{
    static void Main()
    {
        double radius = 5; // 圆的半径
        int pointsCount = 10; // 需要计算的点的数量

        for (int i = 0; i< pointsCount; i++)
        {
            double angle = (double)i / pointsCount * 2 * Math.PI;
            double x = radius * Math.Cos(angle);
            double y = radius * Math.Sin(angle);
            Console.WriteLine($"Point {i + 1}: ({x}, {y})");
        }
    }
}
