cache.Remove(key);
}

public List<Product> GetProductList()
{
// This returns a list of product objects.
}
public void LoadAllProducts(ICacheManager cache)
{
List<Product>list = GetProductList();
for (int i = 0; i < list.Count; i++)
{
Product newProduct = list[i];
cache.Add(newProduct.ProductID, newProduct);
}
}
