Populate dropdown box from SQL Server using a function - vb.net

Question

I am trying to follow this video that is written in C# and convert it to vb (to Populate a dropdown box from SQL Server using a function)
here is the working C# code:
private list<product> getallprodcuts()
{
Try
{
using(PropSolWebDBEntities db= new PropSolWebDBEntities())
list<product> products = (from x in db.product select x).tolist;
}
catch(exception)
{
Return Null;
}
}
And the vb that I cant get to work:
Private Function getallproducts() As List( Of<product>)
Try
Dim db As New PropSolWebDBEntities
Dim products As list <product> = (from x in db.product select x).tolist
Return products
Catch ex As Exception
Return vbNull
End Try
End Function
What am I doing wrong?

Answer 1

List should be translated as List(of product).
return null should be translated as Return Nothing.
Use using instead of declaring the db variable.
I don't compile the code, but it's like this:
Private Function getallproducts() As List(Of product)
Try
Using db As New PropSolWebDBEntities
Dim products As list(Of product) = (From x In db.product Select x).ToList()
Return products
End Using
Catch ex As Exception
Return Nothing
End Try
End Function

You don't need the LINQ part since you are not filtering/grouping/ordering by. The Using block takes care of your context disposal for you. You just missed some syntax difference.
Private Function getallproducts() As List(Of product)
Dim results As List(Of product) = Nothing
Using db As New PropSolWebDBEntities
results = db.product.ToList
End Using
Return results
End Function
