System.OutOfMemoryException -- too many arrays?

Question

Hello, my question is about a c# on .net 2.0 application that I'm building.  I am creating an encyclopedia-like area within the application that holds information about plants.  I've created a few classes for this area that represent different sets of plant information.  Whenever I try to view the details of a plant I'm getting the exception System.OutOfMemoryException and I am having trouble figuring out why. I am using many arrays all at once.  Is it too much for .net to handle?  Can anyone point me toward a more efficient way of coding this?  Here's the portion of offending code:

Thanks,
Joe Dulany

protected void PrintPlantAttributes(plant p)

ArrayList items = new ArrayList();

if (p.height.Length > 0)

{

PlantAttribute paHeight = new PlantAttribute();

paHeight.AttributeName = "Height:";

items.Add(paHeight);

}

if (p.spread.Length > 0)

PlantAttribute paSpread = new PlantAttribute();

paSpread.AttributeName = "Spread:";

paSpread.AttributeList = p.spread.Split(new char[] { ',' });
