c# 2d How to compare two GameObjects ?

Hello,

I am trying to compare a GameObject that is inside an array of GameObjects (which is the map) to just another GameObject, in this case I am trying to see if where the player stands in the map is water, but even when I know for sure it is water they don't compare. can you plz help me ? , this is my code:

 (a script)
 
 public static GameObject[] map;
 map = new GameObject[10];
 
 (b script)
 
 map[0] = Water;
 
 (c script)
 
 if (map[0] == Water) {
             print ("Works");
         } else {
             print ("Doesn't Work");
         }
