Need help for search optimization

Question

I am fairly new to programming and i need some help with optimizing. Basically a part of my method does:

for(int i = 0; i < Tiles.Length; i++)
{
    x = Tiles[i].WorldPosition.x;
    y = Tiles[i].WorldPosition.y;
    z = Tiles[i].WorldPosition.z;

    Tile topsearch = Array.Find(Tiles,
        search => search.WorldPosition == Tiles[i].WorldPosition +
            new Vector3Int(0,1,0));

    if(topsearch.isEmpty)
    {
        // DoMyThing
    }
}

So i am searching for a Tile in a position which is 1 unit above the current Tile. My problem is that for the whole method it takes 0.1 secs which results in a small hick up..Without Array.Find the method is 0.01 secs.

I tried with a for loop also, but still not great result, because i need 3 more checks for the bottom, left and right..

Can somebody help me out and point me a way of acquiring some fast results? Maybe i should go with something like threading?
