Sure:

C:\Program Files\Autodesk\AutoCAD Civil 3D 2013\Sample\Civil 3D API\DotNet\VB.NET\AlignmentSample

The same example shipped with C3D2010-2012

Replace this code in the CreateAlignmentsByLWPolyline function:

         dObjId = CreatePolyline()
         If (dObjId.IsNull) Then
             m_Editor.WriteMessage("Sample Alignment: Error creating a polyline." + Convert.ToChar(10))
             Return False
        End If

With this:

            Dim dObjId As ObjectId
            dObjId = SelectPolyline()
            If (dObjId.IsNull) Then
                m_Editor.WriteMessage("Sample Alignment:  Error getting a polyline." + Convert.ToChar(10))
                Return False
            End If

Then add this Function to the end of the class:

        Public Function SelectPolyline() As ObjectId
            Dim oPoly As ObjectId = Nothing
            Dim entOpts As New PromptEntityOptions("Select polyline:")
            entOpts.SetRejectMessage("...not a LWPolyline, try again!")
            entOpts.AddAllowedClass(GetType(Polyline), True)
            Dim entRes As PromptEntityResult = m_Editor.GetEntity(entOpts)
            If entRes.Status = PromptStatus.OK Then
                oPoly = entRes.ObjectId
            End If
            Return oPoly
        End Function
