将 Dll 嵌入并加载到项目中 - VB.NET / C#

Question

I am currently programming an analyze program to check for trojans and malware. For this I also use Fiddler Core to intercept and analyze traffic of those trojans.

Fiddler Core comes additionally with 3 dlls which need to be in the same start folder as the program itself. As I want my Startup folder to be Exe only without any additional dlls displayed I embedded these 3 dlls in my project as resource and load them in ApplicationEvents.

This way works with all DLLs except one, the CertMaker.dll. It is responsible for creating the root certificate which is needed to intercept the requests.

If I embed the CertMaker.dll it works up to the point that a root certificate is created, but then it does not intercept the requests. I can't get any queries in. It only works if I write the CertMaker.dll from memory into the startup folder but as I wrote above I want the startup folder to be the exe only.

Here is my code in case you need it:

ApplicationEvents.vb:

Namespace My
Partial Friend Class MyApplication
    Private WithEvents Domain As AppDomain = AppDomain.CurrentDomain
    Private Function DomainCheck(sender As Object, e As System.ResolveEventArgs) As System.Reflection.Assembly Handles Domain.AssemblyResolve
        If e.Name.Contains("BCMakeCert") Then
            Return System.Reflection.Assembly.Load(My.Resources.Dll1)
        ElseIf e.Name.Contains("CertMaker") Then
            Return System.Reflection.Assembly.Load(My.Resources.Dll2)
        ElseIf e.Name.Contains("FiddlerCore4") Then
            Return System.Reflection.Assembly.Load(My.Resources.Dll3)
        Else
            Return Nothing
        End If
    End Function
End Class
End Namespace

It works only if I write the CertMaker.dll to the Startup Folder:

 Dim appPath As String = Application.StartupPath()
 File.WriteAllBytes(appPath & "/CertMaker.dll", My.Resources.Dll2)

Is there another way to include and load the dll in the project without the dll appearing in the same startup folder ? I would like to be able to send the program later as a file without the dlls being in the folder.

Answer 1

Use AppDomain.Current.Load(assembly) method if the fiddler's assemblies are.Net based.
