Question

I am coding in vb.net.
At times the data is empty/null this is due to user’s input into the db.
i will like to bypass it, however i get no luck.

here is snippet of my code:

If hct.mydbvalue.name IsNot Nothing Then
   dr("mydbvalue") = hct.mydbvalue.name
End If

I still get an error:

System.NullReferenceException: Object reference not set to an instance of an object.

is there a way if it is a null value to not do anything?

Both @FishBasketGordo and @Yuck are correct, you need to check the full object path for nullability:

If (hct IsNot Nothing) AndAlso (hct.mydbvalue IsNot Nothing) AndAlso (hct.mydbvalue.name IsNot Nothing) Then
   dr("mydbvalue") = hct.mydbvalue.name
End If
