I'm trying to use a multidimensional array of structs in C#. After some time I have managed to write a single row array without fixed length. The code is as follows:

public GameObject block;
public GameObject emptySpace;

public struct cell {
    public int cellRotation;
    public GameObject cellBlock;

    public cell(int r, GameObject b){
        cellRotation = r;
        cellBlock = b;
    }
}

void Start () {
    cell[] map = {
        new cell(90, block), new cell(180, emptySpace), new cell(270, block)
    };
}

I can access the structs' properties easily by doing something like map[0].cellRotation

My question is, how can I define a new multidimensional array of structs of fixed length (say [2,3]) and how could I access it later on? Every single thing I've tried returns an error.

Thanks
