Return multiple values to a method caller

Question

I read the C++ version of this question but didn\'t really understand it.

Can someone please explain clearly if it can be done and how?

Answer 1

Ways to do it:

1) KeyValuePair (Best Performance - 0.32 ns):

    KeyValuePair Location(int p_1, int p_2, int p_3, int p_4)
    {                 
         return new KeyValuePair(p_2 - p_1, p_4-p_3);
    }

2) Tuple - 5.40 ns:

    Tuple Location(int p_1, int p_2, int p_3, int p_4)
    {
          return new Tuple(p_2 - p_1, p_4-p_3);
    }

3) out (1.64 ns) or ref 4) Create your own custom class/struct

ns -> nanoseconds
