使用函数计算c#中数组之间的欧几里得距离 [英] calculate the Euclidean distance between an array in c# with function

问题描述

我想计算用户输入的点之间的欧几里得距离，如您所见:

I want to calculate a euclidean distance between points that the user enter,so as you can see here :

static void Main(string[] args)
{
    int numtest = int.Parse(Console.ReadLine());
    int[,] points=new int[10,2];
    for (int i = 0; i < numtest; i++)
    {
        Console.WriteLine("point " +(i+1).ToString()+" x: ");
        points[i, 0] = int.Parse(Console.ReadLine());
        Console.WriteLine("point " + (i + 1).ToString() + " y: ");
        points[i, 1] = int.Parse(Console.ReadLine());
    }
}

public float[] calculate(int[,] points)
{
    for (int i = 0; i <points.Length ; i++)
    {

    }
}

c#中是否有任何功能可以做到这一点?

is there any function in c# that can do this ?

我需要在数组中所有点之间具有每个距离值

I need to have each distance value between all points in my array

推荐答案

尝试关注

public void calculate(double[,] points)
{
    var distanceArray = new double[points.Length, points.Length];

    for (int i = 0; i < points.Length; i++)
        for (int j = 0; j < points.Length; j++)
            distanceArray[i, j] = Distance(points[i, 0], points[i, 1], points[j, 0], points[j, 1]);
}

public static double Distance(double x1, double y1, double x2, double y2)
=>  Math.Sqrt(((x1 - x2) * (x1 - x2) + (y1 - y2) * (y1 - y2)));
