Question

I want to use a Tuple but in C# 2, it does not exist. I think to replace it by KeyValuePair.

Is it the best way to do this ?

Answer 1

A simple class holding two generic members is probably the best option. This is essentially what Tuple<T1,T2> is.

If you know the types you are using, it is better to create a class with members of those types – this way you can use good naming for the class and members to ensure good readability (which a generic type like Tuple obscures).

From you comment, I would suggest that creating a small wrapper class (or possibly struct) to hold the int values will be the best choice.

Untested:

public class Point
{
   public Point(int xPos, int yPos)
   {
     this.xPos = xPos;
     this.yPos = yPos;
   }

   int xPos;
   int yPos;

   public int XPos { get { return xPos;} set { xPos = value;} }
   public int YPos { get { return yPos;} set { yPos = value;} }
}
