How to return two variables with return?

Question

C++ / C#

This is part of the learning task. It uses my returned value to test the length from segment to point in various cases. I can safely return one of them, but I do not know how to do it together.

public static double GetDistanceToSegment(double ax, double ay, double bx, double by, double x, double y)
    {
      double result = 0;
      double sabx = (ax + bx) / 2;
      double saby = (ay + by) / 2;

      double tandotrez1x = x - ax;
      double tandotrez1y = y - ay;
      double tandotrez2x = x - bx;
      double tandotrez2y = y - by;
      double otrezx = bx - ax;
      double otrezy = by - ay;
      double primouotrezx = sabx - x;
      double primouotrezy = saby - y;

      
      if ((otrezx*primouotrezx+otrezy*primouotrezy)==0)
            {
         result = Math.Pow(Math.Pow(primouotrezx, 2) + (Math.Pow(primouotrezy, 2)), 0.5);
            }
      return result;		
  
      double dlina1 = Math.Pow(Math.Pow(otrezx, 2) + Math.Pow(otrezy, 2), 0.5);
      double dlina2 = Math.Pow(Math.Pow(tandotrez1x, 2) + Math.Pow(tandotrez1y, 2), 0.5);
      double dlina3 = Math.Pow(Math.Pow(tandotrez2x, 2) + Math.Pow(tandotrez2y, 2), 0.5);
      double poluperimetr = (dlina1 + dlina2 + dlina3) / 2;
      double square = Math.Pow(poluperimetr*(poluperimetr-dlina1) * (poluperimetr - dlina2) * (poluperimetr - dlina3), 0.5); //S=1/2*h*a h=2S/a
      double h = 2 * square / dlina1;
      return h;
      


    }

Answer 1

Is very necessary that that use "tuple".
Not the best practice, as they say, but if you need it this way and not otherwise, then why not.

public (int, string) GetUser(){
int a = 14;
string b = "Roman";
return (a,b)
}

Answer 2

complement responders
, you can add arguments to the function, defining them as reference (ref or out keyword), respectively, one or all of the return values ​​can be placed there

Answer 3

There are several options:
1. Return an array
2. Declare your structure or class, which will contain the two required values ​​as fields or properties
3. Return a tuple

Answer 4

return returns something that contains 2 values ​​is either a class or a struct or a perverted delimited string (don't do that)
