Building a large string in vb.net

I have a form that has 3 Tabs and a user will populate dropdowns on the form and then press save.

I then write the string to a text file with a separator between each answer, is there a better way of doing it other than what I have done below?

Dim tesstring As String = " test " & _
         Separator & _
         answer1 & _
         Separator & _
         answer2 & _
         Separator & _
         answer 3 & _
         Separator & _
         answer4 & _
         Separator & _
         answer5 & _
         Separator & _
         Combo_BS.SelectedItem.ToString.Substring(0, 6) & _
         Separator & _
         answer6 & _
         Separator & _
         answer7 & _
         Separator & _
         answer8 & _
         Separator & _
         answer9 & _
         Separator & _
         answer10 & _
         Separator & _
         answer11 & _
         Separator & _
         answer12 & _
         Separator & _
         answer13 & _
         Separator & _
         answer14 & _
         Separator & _
         answer15 & _
         Separator & _
         answer16 & _
         Separator & _
         answer17 & _
         Separator & _
         answer18 & _
         vbCrLf

To expand on Jon's answer, create a collection of answers. For example, if all the answers are in textboxes in a panel called 'Panel1':

    Dim answers = From x In Me.Panel1.Controls.OfType(Of TextBox)() Select x.Text
    Dim tesstring As String = String.Join(Separator, answers)

Yes. Create an array of all the values, and then use String.Join:

Dim tesstring As String = String.Join(Separator, values) & vbCrlf

Ideally, don't have 18 different answer variables to start with - can't those be in a collection?
