[RESOLVED] Embedding DLL resources into Executable (No more ILmerge)

Hello.

I've used ILMerge in the past when I needed to include the DLL's my assemblies depended on and only have to distribute a single exe file.
Jeffrey Richter recently posted some c# code that allows you to embed the DLL's and load them from a byte array as embedded resources.

I wonder if anyone here has done this in VB.net yet?( Without a bunch of off topic discussion about "if this is legal to do")
I've tried to understand how you would do this in VB.net, but I'm kinda at a loss..

Here is the original link

Here's the code sample he gives(in c#), I'm just not sure how to handle the event in VB.net since among many things the sub main is semi hidden and my lack of the appdomain knowledge

Code:

---

AppDomain.CurrentDomain.AssemblyResolve += (sender, args) => {

  String resourceName = "AssemblyLoadingAndReflection." +

      new AssemblyName(args.Name).Name + ".dll";

  using (var stream = Assembly.GetExecutingAssembly().GetManifestResourceStream(resourceName)) {

      Byte[] assemblyData = new Byte[stream.Length];

      stream.Read(assemblyData, 0, assemblyData.Length);

      return Assembly.Load(assemblyData);

  }

};

---

A rough conversion to vb.net

Code:

---

AppDomain.CurrentDomain.AssemblyResolve += Function(sender, args)


Dim resourceName As [String] = "AssemblyLoadingAndReflection." + New AssemblyName(args.Name).Name & ".dll"

Using stream = Assembly.GetExecutingAssembly().GetManifestResourceStream(resourceName)

        Dim assemblyData As [Byte]() = New [Byte](stream.Length - 1) {}

        stream.Read(assemblyData, 0, assemblyData.Length)


        Return Assembly.Load(assemblyData)

End Using

End Function

---

Anyone ever done this before? Perhaps a working code sample?

Thanks in advance!

Never done this but here is how I converted to VB.NET, have not tried it.

Code:

---

Option Strict On
Imports System.Reflection

---

Code:

---

AddHandler AppDomain.CurrentDomain.AssemblyResolve, AddressOf test

---

Code:

---

    Private Function test( _
        ByVal sender As Object, _
        ByVal args As System.ResolveEventArgs) As System.Reflection.Assembly

        Dim resourceName As String = "AssemblyLoadingAndReflection." & _
            New AssemblyName(args.Name).Name & ".dll"

        Using stream = System.Reflection.Assembly.GetExecutingAssembly() _
            .GetManifestResourceStream(resourceName)

            Dim assemblyData(CInt(stream.Length - 1)) As Byte

            stream.Read(assemblyData, 0, assemblyData.Length)

            Return System.Reflection.Assembly.Load(assemblyData)

        End Using
    End Function

---

Ok, just tested it out. Got it working after a little trial and error.

Here was the results.
I placed all the code in the ApplicationEvents.vb

Code:

---

        Private Sub Form1_Startup(ByVal sender As Object, ByVal e As Microsoft.VisualBasic.ApplicationServices.StartupEventArgs) Handles Me.Startup
            AddHandler AppDomain.CurrentDomain.AssemblyResolve, AddressOf LoadDLLFromStream
        End Sub

        Private Function LoadDLLFromStream( _
            ByVal sender As Object, _
            ByVal args As System.ResolveEventArgs) As System.Reflection.Assembly

            Dim resourceName As String = "YourAssemblyName_CaseSensitive." & New AssemblyName(args.Name).Name & ".dll"
            'had to use this line to debug and figure out why it didnt load at first
            Dim resources() As String = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceNames

            Using stream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(resourceName)

                Dim assemblyData(CInt(stream.Length - 1)) As Byte

                stream.Read(assemblyData, 0, assemblyData.Length)

                Return System.Reflection.Assembly.Load(assemblyData)

            End Using
        End Function

---

Worked perfectly after I figured out what the resource name really was...

Thanks for the help.

Good to hear that!
