NullReferenceException

I keep getting NullReferenceException when I create a spirte. It only happens when I close the application, but strangely not the first time I run the application, only after that. I must not be disposing of the texture properly. Can anyone help Here is some of my code:

        private void OnDeviceLost(object sender, EventArgs e)
        {
            if (Tile.sprite != null)
            {
               Tile.sprite.Dispose();
                Tile.sprite = null;
            }
        }

I also tried similiar code in the OnDestroyDevice method and still get the exception. Thank you for any suggestions.

    I tried that and it did not work. I think it has something to do with static members, but I'm new at this so maybe not.

    You should also consider adding another condition to the if, making sure that Tile itself is not null. Therefore, instead of

    if (Tile.sprite != null)

    you should have

    if (Tile != null && Tile.sprite != null)

  • Roger Willcocks

    That's a good idea. I already removed Tile.sprite and created a spirte in the current class and still get the exception. I'm going nuts!

    hy. it might have an answer for you ...or not. maybe you should give up this line

    Tile.sprite = null ; // .sprite is already disposed.
