Content not loading from class

Question

Im trying to build a break out game using C# and the XNA framework. I've placed the brick into a seperate class and created an array for 10 bricks to load. However, when I run the game, no bricks are actually appearing and I can't seem to find the error as Visual Studio isn't flagging anything.

Brick class:

class bricks
{
    Texture2D brickimg;
    Rectangle rectangle;
    int[] brickXPos = new int[50];
    int[] brickYPos = new int[50];

    public bricks(Texture2D NewTexture, Rectangle newRectangle)
    {
        brickimg  = NewTexture;
        rectangle = newRectangle;
    }

    public void Initialize()
    {
        for (int i = 0; i < 50; i++)
        {
            brickXPos[i] = 300 + i * 60;
            brickYPos[i] = 100;
        }
    }

    public void Update()
    {
    }

    public void Draw(SpriteBatch spritebatch)
    {
        for (int i = 0; i < 50; i++)
        {
           spritebatch.Draw(brickimg, new Vector2(brickXPos[i], brickYPos[i]), rectangle, Color.White);
        }
    }
}

Main program:

/// <summary>
/// This is the main type for your game
/// </summary>
public class Breakout : Microsoft.Xna.Framework.Game
{
    GraphicsDeviceManager graphics;
    SpriteBatch spriteBatch;

    public Breakout()

        graphics = new GraphicsDeviceManager(this);

        graphics.PreferredBackBufferHeight = 768;
        graphics.ApplyChanges();
        Content.RootDirectory = "Content";
    }

        BackgroundImg = Content.Load<Texture2D>("starfield");
        bricks = new bricks(Content.Load<Texture2D>("redbrick"),new Rectangle());

            this.Exit();

        base.Update(gameTime);
    }

    /// <summary>

    /// <param name="gameTime">Provides a snapshot of timing values.</param>
    protected override void Draw(GameTime gameTime)
    {
        GraphicsDevice.Clear(Color.CornflowerBlue);

        // TODO: Add your drawing code here

        base.Draw(gameTime);
        spriteBatch.Begin();
            spriteBatch.Draw(BackgroundImg, Vector2.Zero, Color.White);
            bricks.Draw(spriteBatch);
            spriteBatch.End();
    }
}

Answer 1

You never Initialise the bricks object.
You need to call bricks.Initialise(); function somewhere (preferably in the initialise function of the Breakout class).

I would also recommend you to use a bit cleaner code standard.
Class names usually start with upper case, ie: Bricks instead of bricks, in your case, the class and the instance of the class have the same name (bricks) which could create confusion and even should create a compiler error (I think?).
(The 'NewTexture' variable in the constructor of the brick class also suffer from bad naming, should probably rather be named newTexture, especially due to the fact that the Rect is called newRectangle, - but this is not a code-review site, so ill leave that issue for now!).

Answer 2

Try passing null into the sourceRectangle parameter of spriteBatch.Draw in your bricks class. I think the rectangle you're passing in is no good.

spritebatch.Draw(brickimg, new Vector2(brickXPos[i], brickYPos[i]), null, Color.White);
