Error in script - 'Results' is not a member of 'Microsoft.SqlServer.Dts.Tasks.ScriptTask.ScriptObjectModel'

Question

I'm trying to set up a script task in SSIS (my first attempt at doing so, so bear with me).    Part of this is code I have pulled from other examples I found on the internet.    
        Dts.TaskResult = Dts.Results.Success
on the above line, I'm getting error
'Results' is not a member of 'Microsoft.SqlServer.Dts.Tasks.ScriptTask.ScriptObjectModel'
Can you tell me what's wrong?
Imports System
Imports System.Data
Imports System.Math
Imports Microsoft.SqlServer.Dts.Runtime
<System.AddIn.AddIn("ScriptMain", Version:="1.0", Publisher:="", Description:="")> _
<System.CLSCompliantAttribute(False)> _
Partial Public Class ScriptMain
 Inherits Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTARTScriptObjectModelBase
 Enum ScriptResults
  Success = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Success
  Failure = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure
 End Enum
    Public Sub Main()
        Dim mgr As ConnectionManager
        mgr = Dts.Connections("FTP_Connect")
        Dim conn As FtpClientConnection
        conn = New FtpClientConnection(mgr.AcquireConnection(DBNull.Value))
        Dim fileNames(0) As String
        fileNames(0) = "LEVEL01.TESTFILE"  'user can avoid using / in file name here
        Try
            conn.Connect()
            conn.ReceiveFiles(fileNames, "c:\holddata", True, True)
        Catch ex As Exception
        Finally
            conn.Close()
        End Try
        Dts.TaskResult = Dts.Results.Success
    End Sub
End Class

I think error is here - Dts.TaskResult = Dts.Results.Success, it can't find the enumerator
name "Results". The enumerator name that you gave (or by default) "ScriptResults"
Enum
ScriptResults
  Success = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Success
  Failure = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure
 End Enum
So, try with this statement 
 Dts.TaskResult = Dts.ScriptResults.Success
//this is last 3rd line from bottom
