How AddHandler from C# DLL to VB Proj

Someone know how addhandlers from C# DLL to VB App. When I try to use AddHandler into my VB project, the Visual Studio returns:

Error BC30676 'DebugMessageEvent' is not an event of 'Debugger'...

Attachment 142821

If I go to the 'DebugMessageEvent' definition from VB Proj (Auto-Converted from the DLL called DLLNAMESPACE), I get the follow code:

Code:

---

Public Class Debugger
    Public DebugMessageEvent As EventHandler(Of DebugMessageArgs)

    Public Shared ReadOnly Property Instance As Debugger

    Public Class DebugMessageArgs
        Inherits EventArgs

        Public Sub New()

        Public Property Message As Object
    End Class
End Class

---

The VB Project (Doesn't Work)

Code:

---

AddHandler Instance.DebugMessageEvent, AddressOf console_DebugMessageEvent

---

Another C# project (Works)

Code:

---

Debugger.Instance.DebugMessageEvent += console_DebugMessageEvent;

---

The DLL C# Code

Code:

---

public sealed class Debugger
{
    private static readonly Lazy<Debugger> instance = new Lazy<Debugger>(() => new Debugger());

    private Debugger()
    {

    }

    public static Debugger Instance
    {
        get { return instance.Value; }
    }

    public EventHandler<DebugMessageArgs> DebugMessageEvent;

    public class DebugMessageArgs : EventArgs
    {
        public object Message { get; set; }
    }

    private void RaiseDebugMessageEvent(object message)
    {
        DebugMessageEvent?.Invoke(this, new DebugMessageArgs
        {
            Message = message
        });
    }

    internal void DebugMessage(object data)
    {
        RaiseDebugMessageEvent(data);
    }
}

---

All the rest of DLL functions works as expected.

It's not actually declared as an event, for some curious reason. If it were an event, it would look like:

Code:

---

public event EventHandler<DebugMessageArgs> DebugMessageEvent;

---

Since it's not an event, it's just a delegate field, and that means AddHandler/RemoveHandler won't work with it. You'll have to do something janky like:

Code:

---

Dim handler As New EventHandler(Of DebugMessageEventArgs)(AddressOf yourHandler)
Debugger.Instance.DebugMessageEvent = handler

---

This isn't a "C# to VB" problem, this is a "the person writing the code made a bad mistake" problem.

When I try your code with:

Code:

---

Imports DLLNAMESPACE
Public Class myclass
        ...
        Dim fixDebugMessageEvent As New EventHandler(Of Debugger.DebugMessageArgs)(AddressOf console_DebugMessageEvent)
        Private Sub backup(...)
                Debugger.Instance.DebugMessageEvent = fixDebugMessageEvent
                ...
        End Sub
        ...
        Private Sub console_DebugMessageEvent(sender As Object, e As Debugger.DebugMessageArgs)
        Console.WriteLine("Consola RoboSharp: " & e.Message)
    End Sub
        ...
End Class

---

also with:

Code:

---

Imports DLLNAMESPACE
Public Class myclass
        ...
        Private Sub backup(...)
                Debugger.Instance.DebugMessageEvent = New EventHandler(Of Debugger.DebugMessageArgs)(AddressOf console_DebugMessageEvent)
                ...
        End Sub
        ...
        Private Sub console_DebugMessageEvent(sender As Object, e As Debugger.DebugMessageArgs)
        Console.WriteLine("Consola RoboSharp: " & e.Message)
    End Sub
        ...
End Class

---

I get a new error:

Code:

---

Exception thrown: 'System.InvalidOperationException' in System.dll

---

Maybe I should mod the DLL code

Thanks,
