How To Convert DT_NTEXT To DT_WSTR In Script Component

The IC column referenced in the script below is DT_NTEXT, so when I run it the output value column gets "Microsoft.SqlServer.DTS.Pipeline.BlobColumn" instead of the individual codes (separated by "*"). Also, there is only 1 output row per input row, instead of 1 output row per code.

I found some references to the GetBobData() method, but replacing Row.IC.ToString() with Row.IC.GetBlobData(0, CInt(Row.IC.Length)).ToString() puts "System.Byte[]" in the value output column. There is still only output row per input row.

So how do I convert the IC column to a String that can be Split()?Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
Dim seq As Integer = 0
For Each code As String In Row.IC.ToString().Split("*"c)
'Add a row to the output buffer:
Output0Buffer.AddRow()

'Preserve columns from the input buffer:
Output0Buffer.itemid = Row.itemid
Output0Buffer.attributeid = Row.attributeid
'Output0Buffer.IC = Row.IC

'Add output columns:
Output0Buffer.seq = seq
Output0Buffer.value = code
seq += 1
Next
End Sub
