Is it Possible to Return a Reference to a Variable in C#? [duplicate]

Answer 1

After some thinking, why not send the value to be set with the function like this:

void SetElement(double value)
{
   ......
   // Calculate x,y,z
   doubleArray[x,y,z]=value;
}

and use it:

void func()
{
   SetElement(5.0);
}

However, I will still choose one of your helpful answers...
