Hi there i know this has been covered before, but we're still not quite
getting there.

We found the following post
http://blogs.msdn.com/yuxiangxu/archive/2004/06/29/169123.aspx on Andy
Xu's blog. However we tried to do a quick code translation from VB.NET
to C# - and we may have got this wrong. But the code does not work as
expected.

Taking the code in Andy's blog post, we have come up with the following
code, and when run we get an invalid cast exception. Any ideas please?:

OrderForm cartOrderForm = basket.OrderForms[0];
ISimpleList discountApplicationRecords;
int campaignItemID;
decimal discountAmount;

//assume basket pipeline is exeecuted and we get the orderForm in
variable cartOrderForm

discountAmount = 0;
foreach(LineItem item in cartOrderForm.LineItems)
{

if(!(item["_itemlevel_discounts_applied"].Equals(System.DBNull.Value)))
{
discountApplicationRecords =
(ISimpleList)item["_itemlevel_discounts_applied"];

foreach(System.Collections.IDictionary discountApplicationRecord in
discountApplicationRecords)
{
campaignItemID = (int)discountApplicationRecord["discount_id"];

if(campaignItemID == 1)
{
discountAmount +=
(decimal)discountApplicationRecord["cy_discount_amount"];
}
}
}
}

return discountAmount;

Sorry, i should have said where this error was happening !!

its the cast to IDictionary of the foreach part where the cast
exception occurs.

TIA
