Null Deference findings are most often associated with FOR EACH loops. This finding can be dropped by rewriting the loop as a simple FOR loop.
For instance, this code:
Dim MyList As New List(Of String) For Each Item As String In MyList Item = Item & ": LOOPED!," Next
could be rewritten like this to drop the Null Dereference finding:
Dim MyList As New List(Of String) For StringIndex As Integer = 0 To MyList.Count - 1 Step 1 MyList(StringIndex) = MyList(StringIndex) & ": LOOPED!," Next
