Unity 3D: how to create Texture2D from Sprite2D

private Texture2D GetSpriteTexture(Sprite sprite)
{
    int x = Mathf.FloorToInt(sprite.rect.x);
    int y = Mathf.FloorToInt(sprite.rect.y);
    int w = Mathf.FloorToInt(sprite.rect.width);
    int h = Mathf.FloorToInt(sprite.rect.height);
    Color[] pixels = sprite.texture.GetPixels(x, y, w, h);
    var texture = new Texture2D(w, h, TextureFormat.ARGB32, false);
    texture.SetPixels(pixels);
    texture.Apply();
    return texture;
