Get image of xml

Good morning.

I have an xml where I keep the routes of some images.

my application creates a button for each route I have in the post xml, but I can not get the button to be created with the image in the routes, put an image of? which I think is the one with unity by default.

Would someone know how to help me and tell me where the fault is?

with this I read the xml (it works well)

 public Datos ReadXmlTest() {
        XmlSerializer serializer = new XmlSerializer(typeof(Datos));
        StreamReader reader = new StreamReader(xmlPath);
        Datos data = (Datos)serializer.Deserialize(reader);
        reader.Close();

        return data;
    }

and then I have this one to generate the buttons for each element in the xml (it works fine) and then the part to put the image that works badly ..

  void Awake() {
        string path = "C:/datos.xml";
        XmlManager xmlMng = new XmlManager(path);

        data = xmlMng.ReadXmlTest();

        foreach (var juego in data.Juegos) {
            Button newButton = Instantiate(buttonPrefab);
            newButton.transform.SetParent(layout);
            newButton.GetComponent<AppButton>();

            Sprite imageSprite = new Sprite();
            Texture2D SpriteTexture = Texture(path);
            imageSprite = Sprite.Create(SpriteTexture, new Rect(, , SpriteTexture.width, SpriteTexture.height), new Vector2(, ), 100.0f);
            newButton.image.sprite = imageSprite;
        }
    }

    public Texture2D Texture(string Path) {

        Texture2D Texture2D;
        byte[] FileData;

        if (File.Exists(Path)) {

            FileData = File.ReadAllBytes(Path);
            Texture2D = new Texture2D(1, 1);

            if (Texture2D.LoadImage(FileData))
                return Texture2D;

        }
        return null;
    }

my xml is:

<?xml version="1.0" encoding="utf-8"?>
<Datos>
  <dato>

    <prueba>
      <ruta>C:/exe.exe</ruta>
      <img>C:/Titulo.png</img>
    </prueba>


     <prueba>
      <ruta>C:/exe1.exe</ruta>
      <img>C:/titulo1.png</img>
    </prueba>


  <Datos>
