Handling events in VB.NET vs C#

[martin rydman]

Hi all!

I've been trying to figure out how to do the stuff below in C#. That is,
declare an event with an arbitrary parameter-list, raise it, and, in a client,
declare a variable WithEvents, and then consume the event. Actually, it's
the parameter-list part that's important (specifically to be able to keep
the arbitrary parameter-list).


In component(CSIEFil):
----------------------
Declare:
Public Event SIEImportProgress(ByRef Message As String)

Raise:
RaiseEvent SIEImportProgress("Some message")


In client:
----------
Declare:
Private WithEvents SIEFil As CSIEFil

Consume:
Private Sub SIEFil_SIEImportProgress(ByRef Message As String) Handles SIEFil.SIEImportProgress


TIA!

Martin,
It should go something like this:

In component(CSIEFil):
public delegate void SIEImportProgressHandle(string Message);

Declare:
public event SIEImportProgressHandler SIEImportProgress;


//Raise:
SIEImportProgress("Some message");


//In client:
----------
Declare:
Private CSIEFil SIEFil;
SIEFil.SIEImportProgress+= new SIEImportProgressHandler (SIEFil_SIEImportProgress);

//Consume:
Private void SIEFil_SIEImportProgress(string strMessage)
{
//Put code here
}
