LINQ - Select Statement - The null value cannot be assigned to a member with type System.Int32 which
- by thiag0
I am trying to achieve the following...
_4S.NJB_Request request =
(from r in db.NJB_Requests
where r.RequestId == referenceId
select r).Take(1).SingleOrDefault();
Getting the following exception...
Message:
The null value cannot be assigned to a member with type System.Int32 which is a non-nullable value type.
StackTrace:

I have verified that 'referenceId' does have a value.
Anyone know why this would happen in a select statement?
Thanks!
