Create a .net class and run it as object from your AutoIt script

Recommended Posts

Write a code file in your @ScriptDir like hello.vb

Imports System.Collections.Generic
Imports System.Text
Imports System.Runtime.InteropServices

Namespace myDotNetLibrary
  <ClassInterface(ClassInterfaceType.AutoDual)> _
  Public Class myDotNetClass
    Private myProperty As String

    Public Sub New()
    End Sub

    Public Function myDotNetMethod(input As String) As String
      Return "Hello " & input
    End Function

    Public Property myDotNetProperty() As String
        Return myProperty
      End Get
      Set(ByVal value As String)
        myProperty = value
      End Set
    End Property

  End Class
End Namespace

and run it from your AutoIt script

$vbc = "C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\vbc.exe" ;  ; check the path of your version
$RegAsm = "C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe" ; check the path of your version

RunWait($vbc & " /target:library hello.vb", @ScriptDir, @SW_HIDE) ; compile the .net DLL
RunWait($RegAsm & " /codebase hello.dll", @ScriptDir, @SW_HIDE) ; register the .net DLL

$obj = ObjCreate("myDotNetLibrary.myDotNetClass")
$obj.myDotNetProperty = "AutoIt-World"
ConsoleWrite("! " & $obj.myDotNetMethod($obj.myDotNetProperty) & @CRLF)

RunWait($RegAsm & " /unregister hello.dll", @ScriptDir, @SW_HIDE) ; unregister the .net DLL

dito for C#: multsub.cs

using System;
using System.Collections.Generic;
using System.Runtime.InteropServices;

namespace myCSLibrary
  public class MultSubClass
    private int myProperty;
    public MultSubClass()
    public int mult2(int input)
      return 2 * input;
    public int sub1(int input)
      return input - 1;

    public int myDotNetProperty {
      get { return myProperty; }
      set { myProperty = value; }

and the AutoIt script:

$csc = "C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\csc.exe" ; check the path of your version
$RegAsm = "C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe" ; check the path of your version

RunWait($csc & " /target:library multsub.cs", @ScriptDir, @SW_HIDE) ; compile the .net DLL
RunWait($RegAsm & " /codebase multsub.dll", @ScriptDir, @SW_HIDE) ; register the .net DLL

$obj = ObjCreate("myCSLibrary.MultSubClass")
$obj.myDotNetProperty = 3
ConsoleWrite("! " & $obj.sub1($obj.mult2($obj.sub1($obj.mult2($obj.myDotNetProperty)))) & @CRLF)

RunWait($RegAsm & " /unregister multsub.dll", @ScriptDir, @SW_HIDE) ; unregister the .net DLL

Tested with Windows XP SP3 and .net Framework 3.5/4

Hi paulpmeier,

what a shame, that I've never seen before this thread. :D

I like this idea, to make NET available with AutoIt. Because that, I feeled me free to cast this in an function - hope you like it.

The function loads given .vb or .cs file and register the related dll file. On AutoIt-Exit or new call of this function, the dll will unregister.

I've implemented an automatically NET-detection. On my system (Win7 pro, 32bit, SP1) the required files only included in NET2.0 and 4.0. Because that, I ask only for this installation folder.

Here is the function:

#Region - TimeStamp
; 2011-11-08 13:43:46   v 0.1
#EndRegion - TimeStamp

    Local $sRoot = RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework", "InstallRoot")
    If @error Then Return SetError(3,0,0) ; == NET Framework 2.0 or 4.0 required!
    Local $aFolder = _FileListToArray($sRoot , "*", 2), $sNETFolder = ''
    For $i = $aFolder[0] To 1 Step -1
        If StringRegExp($aFolder[$i], "v4\.0\.\d+", 0) Then
            $sNETFolder = $aFolder[$i]

    If $sExt = '.vb' Then
        RunWait($sRoot & $sNETFolder & "\vbc.exe /target:library " & $sVB_CS_File, @ScriptDir, @SW_HIDE) ; compile the .net DLL
        RunWait($sRoot & $sNETFolder & "\csc.exe /target:library " & $sVB_CS_File, @ScriptDir, @SW_HIDE) ; compile the .net DLL
    $__User_NET_Dll = StringTrimRight($sVB_CS_File, 2) & 'dll'
    $__RegAsmPath = $sRoot & $sNETFolder & "\RegAsm.exe"
    RunWait($__RegAsmPath & " /codebase " & $__User_NET_Dll, @ScriptDir, @SW_HIDE) ; register the .net DLL
    Return 1
EndFunc  ;==>_NETFramework_Load

Func __UnLoad_NET_Dll()
    RunWait($__RegAsmPath & " /unregister " & $__User_NET_Dll, @ScriptDir, @SW_HIDE) ; unregister the .net DLL

Now your example looks so:

#include 'NETFramework.au3'

$obj = ObjCreate("myDotNetLibrary.myDotNetClass")
$obj.myDotNetProperty = "AutoIt-World"
ConsoleWrite("! " & $obj.myDotNetMethod($obj.myDotNetProperty) & @CRLF)

_NETFramework_Load('multsub.cs') ; == unload automatically "hello.vb"
$obj = ObjCreate("myCSLibrary.MultSubClass")
$obj.myDotNetProperty = 3
ConsoleWrite("! " & $obj.sub1($obj.mult2($obj.sub1($obj.mult2($obj.myDotNetProperty)))) & @CRLF)

But now I've a question:

To create own classes and use them - it works fine. Have you always tried to get access to existing NET classes on this way?

Hallo BugFix,

danke für Ihre schöne Funktion, sie macht die Einbindung von .Net-DLLs in AutoIt-Skripte einfacher und eleganter.

Ich bin nicht der große .Net-Experte und da im Mai keiner auf diesen Post hier reagierte, habe ich das Thema auch nicht weiterverfolgt.

Was den Zugriff auf vorhandene .Net-Klassen angeht, habe ich noch versucht die Ideen von

Robert Giseke umzusetzen. Giseke hat ein C# Project Template for Unmanaged Exports geschrieben, mit dem ich eine .Net-DLL erzeugt habe, die auf die DateTime.AddDays-Methode zugreift.


Anbei meine ungeordneten Experimente incl. Links.

Ich hoffe, das hilft Ihnen etwas weiter. Für tiefergehende Informationen müsste ich mich leider erst selbst wieder in die Thematik einarbeiten.

Viele Grüße

Vielen Dank Paul, für Code und Links.

Ich werde in nächster Zeit versuchen mich in diese Thematik etwas tiefer einzuarbeiten. Ich möchte einige NET-Controls in AutoIt verfügbar machen (z.B. Progressbar mit Text-Eigenschaft). Sollten diese Versuche Erfolg haben, werde ich das auch im Forum posten.


So, that you have a chance to understand:

My destination is to learn something more about NET and, if possible, create functions to get acces of some NET-controls (i.e. progress bar with text-property).

If successful, i'll post it.

Best Regards BugFix
