I have an IList , I also have a method which checks if the item is already in list and if it is I need it to be deleted/ removed and add again.
private PurchaseItemViewModel CheckSessionPurchaseItemViewModel(long purchaseLevelId)
{
bool itemFound = false;
PurchaseItemViewModel purItem = new PurchaseItemViewModel();
foreach (var item in UserSession.UserDataPurchaseItems)
{
if (item.PurchaseLevelId == purchaseLevelId)
{
itemFound = true;
purItem.Note = item.Note;
purItem.PurchaseAmount = item.PurchaseAmount;
purItem.PurchaseLevelId = item.PurchaseLevelId;
}
}
if (itemFound)
{
return purItem;
}
return null;
}
If it the above method finds the purchase item then it returns an object else null.
IList<PurchaseItemViewModel> purchaseSessionList = UserSession.UserDataPurchaseItems;
PurchaseItemViewModel pItem = CheckSessionPurchaseItemViewModel(levelId);
if(pItem != null)
{
purchaseSessionList.Remove(item);
}
So the issue is with the below line it is not removing the item , it does not even error.
**purchaseSessionList.Remove(item);**
Use this code for removing:
if(pItem != null) purchaseSessionList.Remove( purchaseSessionList.SingleOrDefault( s => s.PurchaseLevelId== levelId) );
IMHO you don't need to create pItem, would be enough to return false or true or item primary key.
