LinqToXML why does my object go out of scope? Also should I be doing a group by?
- by Kettenbach
Hello All,
I have an IEnumerable<someClass>. I need to transform it into XML. There is a property called 'ZoneId'. I need to write some XML based on this property, then I need some decendent elements that provide data relevant to the ZoneId. I know I need some type of grouping. Here's what I have attempted thus far without much success. **inventory is an IEnumerable<someClass>. So I query inventory for unique zones. This works ok.
var zones = inventory.Select(c => new {
ZoneID = c.ZoneId
, ZoneName = c.ZoneName
, Direction = c.Direction
}).Distinct();
No I want to create xml based on zones and place. ***place is a property of 'someClass'.
var xml = new XElement("MSG_StationInventoryList"
, new XElement("StationInventory"
, zones.Select(station =>
new XElement("station-id", station.ZoneID)
, new XElement("station-name", station.ZoneName))));
This does not compile as "station" is out of scope when I try to add the "station-name" element. However is I remove the paren after 'ZoneId', station is in scope and I retreive the station-name. Only problem is the element is then a decendant of 'station-id'. This is not the desired output. They should be siblings. What am I doing wrong? Lastly after the "station-name" element, I will need another complex type which is a collection. Call it "places'. It will have child elements called "place". its data will come from the IEnumerable and I will only want "places" that have the "ZoneId" for the current zone. Can anyone point me in the right direction? Is it a mistake select distinct zones from the original IEnumerable? This object has all the data I need within it. I just need to make it heirarchical. Thanks for any pointers all.
Cheers,
