在 C# 中编码距离和角度

Question

我正在用 C# 编写我的第一个程序，但在计算距离和角度的方程式时遇到了问题。我的目的是提示输入一个X1，Y1值，一个X2，Y2值，并计算两点之间的距离和角度。我将在下面粘贴我的（非常可怕的）代码。在此先感谢您的帮助！

        //prompt and store the x and y for two points
        Console.WriteLine("Please enter X1:");
        float point1X = float.Parse(Console.ReadLine());
        Console.WriteLine("Please enter Y1:");
        float point1Y = float.Parse(Console.ReadLine());
        Console.WriteLine("Please enter X2:");
        float point2X = float.Parse(Console.ReadLine());
        Console.WriteLine("Please enter Y2:");
        float point2Y = float.Parse(Console.ReadLine());
        Console.WriteLine("");

        //calculate the distance
        double deltaX= Math.Pow(point2X - point1X, 2);
        double deltaY= Math.Pow(point2Y - point1Y, 2);
        Console.WriteLine("double deltaX, double deltaY");
        Console.WriteLine("");

        //calculate the angle
        double angle = Math.Atan2(deltaX, deltaY);
        Console.WriteLine("double angle");
        Console.WriteLine("");

Answer 1

如果这是您搜索的类似内容，那么这是数学，而不是 C# ;-) :

        //calculate the distance
        ...
        Console.WriteLine("Distance : " + Math.Sqrt(deltaX + deltaY));

        //calculate the angle
        double angle = Math.Atan2(point2Y - point1Y, point2X - point1X);
        ...
        Console.WriteLine(angle + " Rad");
        Console.WriteLine(angle * 180 / Math.PI + " Deg");
