How do I programatically access Type Properties from an Order's line item?

I have defined several products with custom property types, like "Color" and "InternalProductCode". In the checkout.aspx, I am looping through the line items in the basket with code like: Code:
Dim lineItem as BVSoftware.Bvc5.Core.Orders.LineItem
For Each lineItem in Basket.Items
'*** Here, I would like to access the custom property types of the lineItem
How can I get to the values of the custom property types from the line Item? I have looked at the lineItem.AssociatedProduct and everything else I can think of in the debugger. But can't find the right property. Any times?

Does this help? Code:
ProductType pt = ProductType.FindByBvin(lineitem.AssociatedProduct.ProductTypeId);
List<ProductProperty> props = ProductType.FindPropertiesForType(pt.Bvin);
foreach (ProductProperty property in props)
{
string value = InternalProduct.GetPropertyValue(lineitem.AssociatedProduct.Bvin, property.Bvin);
}

Nice. Seems like that would be a handy collection to hang off the LineItem object. There is one problem, though. If the value is a dropdown list item, it looks like I get a BVIN style number, like "1212313-123123-123123-12312312313". How do I look up the string value for that? Just for posterity, here is the code in VB: Code:
Dim pt As ProductType = ProductType.FindByBvin(lineItem.AssociatedProduct.ProductTypeId)
Dim props As System.Collections.Generic.List(Of ProductProperty) = ProductType.FindPropertiesForType(pt.Bvin)
Dim pp As ProductProperty
For Each pp In props
Dim value As String = InternalProduct.GetPropertyValue(lineItem.AssociatedProduct.Bvin, pp.Bvin)
Next
Thanks.

Here is the answer to the second part of the question: If the product type has a list of choices, then Internal.GetPropertyValue(...) will return the bvin of a ProductPropertyChoice object. The ProductPropertyChoice collection must then be searched. The following function handles the details: Code: ''' <summary> ''' Lookup the value of a line item's product type by key. ''' </summary> ''' <param name="lineItem"></param> ''' <param name="key"></param> ''' <returns></returns> ''' <remarks></remarks> Public Shared Function GetProductTypeValue(ByRef lineItem As LineItem, ByVal key As String) As String Dim pt As ProductType = ProductType.FindByBvin(lineItem.AssociatedProduct.ProductTypeId) Dim props As System.Collections.Generic.List(Of ProductProperty) = ProductType.FindPropertiesForType(pt.Bvin) Dim pp As ProductProperty For Each pp In props If pp.DisplayName = key Then Dim ppc As System.Collections.Generic.List(Of ProductPropertyChoice) = ProductPropertyChoice.FindByPropertyID(pp.Bvin) If ppc.Count = 0 Then Return InternalProduct.GetPropertyValue(lineItem.AssociatedProduct.Bvin, pp.Bvin) Else '*** For items with choices, the property value contains the BVIN of the choice... Dim bvin As String bvin = InternalProduct.GetPropertyValue(lineItem.AssociatedProduct.Bvin, pp.Bvin) For Each choice As ProductPropertyChoice In ppc If choice.Bvin = bvin Then Return choice.ChoiceName End If Next Return "" End If End If Next '*** Not found. Return "" End Function
