Dealing with a null datetime element within xml using linq
- by diver-d
HI
I have an example document that looks like
<ItemEntry>
<PurchaseDate>2010-03-18T20:36:32.81108+13:00</PurchaseDate>
<StoreGUID>0a0324ad-5f99-486a-a2d0-870bc6991e9f</StoreGUID>
<ExpiryDate />
<CardID>111111</CardID>
<PurchaseAmount>0</PurchaseAmount>
<RedeemedAmount />
<EntryType>1</EntryType>
<RedeemedDate />
<SalesAssistantID>0</SalesAssistantID>
</ItemEntry>
As you can see there are couple of elements ExpiryDate and RedeemedDate are are empty.
var q = from c in xml.Elements("ItemEntry")
select new mdDetail {
PurchaseDate = (DateTime)c.Element("PurchaseDate"),
StoreGUID = (Guid)c.Element("StoreGUID"),
ExpiryDate = (DateTime?)c.Element("ExpiryDate")??DateTime.MinValue,
CardID = (int)c.Element("CardID"),
PurchaseAmount = (double)c.Element("PurchaseAmount"),
RedeemedAmount = (double?)c.Element("RedeemedAmount"),
EntryType = (int)c.Element("EntryType"),
RedeemedDate = (DateTime?)c.Element("RedeemedDate") ??DateTime.MinValue,
SalesAssistantID = (int)c.Element("SalesAssistantID"),
}
;
foreach (var item in q)
{
}
I am not sure how to deal with the null element value,
I have tried ??DateTime.MinValue and ??null however both give me a "
String was not recognized as a valid DateTime." error.
Any suggestions?
Thank you
