I keep getting a "NullReferenceExeption was unhandled" with "Object reference not set to an instance of an object." written under it. I have all of the images (png) correct with names and added to references.

protected override void LoadContent()
{
spriteBatch = new SpriteBatch(GraphicsDevice);

backGround = Content.Load("Cracked");

player1.playerBlock = Content.Load("square");

player2.playerBlock = Content.Load("square2"); }

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
