SharePoint 2013 WCF Reading a list with a column to allow multiple lookup values

Question

Hi Team,
I'm using SP2013 default WCF in _vti/bin/ListData.svc to read a list.
This list has a look up column and it allows multiple values. While I read the list, I'm not able to retrieve this column as list.
For Example, my parent list is 'VehicleList' and this has a column called-ColorLookUp (lookup with allow multiple values) linked to the 'ColorsList'.
Pseudo Code:
var vehicleItemsList=spcontext.VehicleList.toList(); 
foreach(var item in vehicleItemsList)
var colorItemList=item.ColorLookUp
I'm expecting the 'colorItemList' should have values but it always gives me the count=0. But the same lookup column works if I dont allow multiple values.
Please help me on this.
thanks

Hi,
For the Lookup column, “Expand” is required if you want to get it through ListData.svc.
A code snippet for your reference:
var items = dc.List1.Expand("MyLookupColumn1");
foreach (var item in items)
Console.WriteLine(item.Title);
foreach (var lk in item.MyLookupColumn1)
Console.WriteLine(lk.Title + "---" + lk.Path);
Feel free to reply if there still any questions.
Thanks
