First I'm changing the names slightly to adhere to Unity (and c#) coding conventions. These aren't errors but it's good to stick to:

"Tile_Info" becomes "TileInfo"

“maparray” becomes “map”

“Varriation” becomes “variation”

Now, declare the array like this:

TileInfo[,] map = new TileInfo[width,height];

Next, make sure you populate the array cells with instances of TileInfo, using something like this for each cell which contains a tile:

// fill out the empty array with TileInfo instances:
for (int x=0; x<width; ++x) {
    for (int y=0; y<height; ++y) {
        map[x, y] = new TileInfo();
    }
}

Then you can use the array like this:

TileInfo thisTile = map[x,y];
thisTile.ID = someValue;
thisTile.variation = someValue;

Or directly access the tile's variables:

map[x,y].ID = someValue;
map[x,y].variation = someValue;

And the same for testing:

if (map[x,y].ID == someValue) { ... }

hope this helps!
