Handling events with C# raised from VB.NET

Question

I'm trying to manage some event.

I've my main project, written in C#, and I've added another project, written in VB.NET.

In the VB.NET project, I've a class, raising an event:

Public Class newMessageArgs
    Inherits EventArgs
    Public Property messageCode As String
    Public Property appName As String
End Class

Public Class EventRaiser

    Event NewMessage As EventHandler

    Sub MessageEvent(ByVal typeEvent As String, ByVal messageCode As String, appName As String)
        If typeEvent = "newMessage" Then
            Dim args As newMessageArgs = New newMessageArgs()
            args.appName = appName
            args.messageCode = messageCode
            RaiseEvent NewMessage(Me, args)
        End If
    End Sub
End Class

The method raising the event, is called from my VB.NET code, but I have to handle it with my C# code. How can I do it?

This event isn't binded to any xaml element.

CODE UPDATED:

Trying to handle the event:

attivazione.EventRaiser raiser = new attivazione.EventRaiser();

raiser.NewMessage += raiser_NewMessage; //error: "no overloads for raiser_NewMessage matches the delegate system.eventhandler", underlining red raiser_NewMessage



private void raiser_NewMessage(object sender, newMessageArgs e)
{
   //handle your event here
}

Attivazione is the name of the class in VB.NET that raises the event.

Answer 1

Are you intend something like this?

var raiser = new EventRaiser();
raiser.NewMessage += raiser_NewMessage;

private void raiser_NewMessage(object sender, EventArgs e)
{
    //handle your event here
}

But newMessageArgs class and NewMessage event should be public in your VB code.

And of course, you should add reference to assembly with your VB code into C# project.
