LINQ basic learning question

Hello.  Why does this work: Dim db AsNew SafeTekUSADataClassesDataContextDim
FName = (From p In db.Company_Memberships Where p.EmpUserID = user_currentUserID
Select p.FirstName).First.ToString()

Label10.Text = FName

_________

But this one doesn't?  It only returns one record so the "First, is
actually selecting the only possible record.  If someone can help me undestand
this I would appreciate it!Dim db AsNew SafeTekUSADataClassesDataContext

Dim FName = From p In db.Company_Memberships Where p.EmpUserID =
user_currentUserID Select p.FirstName.ToString()

Label10.Text = FName

Your second query is returning a result set of all those records matching your
WHERE clause. Even though this may return a single record, it is returned as an
IEnumerable result set which contains a single element. Therefore, this result
set CAN NOT be applied to the Text property of your Label.

Your first query guarantees that a single object will be returned and the
FirstName of that object CAN be applied to the Text property of your Label.

Great, thanks much!
