Answer 1

What you refer to is called indexers . In c#, to create indexers, you use the keyword this , followed by square brackets and then get (and an optional set):

public int this[int index]
{
    get { return arr[i]; }
    set { arr[i] = value; }
}

In your case it's not really obvious what your code should go, but I think you are looking for something like this:

private int xx[2];

public int this[index] 
{
    get { return xx[index]; }
    set { xx[index] = value; }
}
