How to set Sprite width and height to match parent-object width and height in-code?
I have instantiated a sprite. I have set the sprite as a child of an empty game object ( PARENT ). PARENT has a width and height stored in RectTransform. How can I set the Sprite rect to match the PARENT rect ( I would like the sprite to have the same width and height as the parent object ).
Code
tCardDisplay = GameObject.Find("CardDisplay").transform;
tCardRowPos = GameObject.Find("CardRowPos").transform;
rectCardRowPos = GameObject.Find("CardRowPos").GetComponent<RectTransform>();
GameObject go = new GameObject();
Sprite sp = Instantiate(Resources.Load<Sprite>("card_blank_v000"),
new Vector3(0, 0, 0),
Quaternion.identity);
SpriteRenderer sr = go.AddComponent<SpriteRenderer>();
sr.sprite = sp;
This code loads the Sprite properly. The Sprite is used on multiple screens so I would like to resize it to suit the current screen ( whichever ). Upon Instantiation the Sprite is larger than the PARENT object. I am not sure how to resize the Sprite to match the PARENT object. Thanks for any replies.

I don't have Unity and can't give you a solution that is 100% going to work, but in the SpriteRenderer component you can get a value of SpriteRenderer.Bounds.Extents that will give you the size of a sprite, I would have to toy with it to make sure it will work for you, but here is the documentation on that.
Assuming that parent (below) is the game object that includes SpriteRenderer, this is how it worked for me:
var parent = (gameObject.transform as RectTransform);
var sprite = GetComponent<SpriteRenderer>().sprite;
parent.localScale = parent.rect.size / sprite.rect.size * sprite.pixelsPerUnit;
