The inDirection should be the velocity of your ball and the inNormal should be the unit vector that is perpendicular to your wall.

Try putting this in your ball object:

void OnCollisionEnter(Collision collision)
{
    Vector2D inDirection = GetComponent().velocity;
    Vector2D inNormal = collision.contacts[0].normal;
    Vector2D newVelocity = Vector2D.Reflect(inDirection, inNormal);
}

NOTE: I cannot currently test that code, so it may need tweaking in terms of the names of things.
