c# EndLisp event handler

[adsylva]

Trying to write an event handler for a lisp routine ending.  This is what I've come up with Based on other event handlers examples;

[CommandMethod("Test1")]

static

public void Test1() // This method can have any name

{

 .....

Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;

doc.LispEnded +=

new ???????(OnLispEnded);

....

}

private void OnLispEnded(object sender, CommandEventArgs e)

{

Editor ed = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor;

Document doc = sender as Document;

ed.WriteMessage("...LispEnded = " + e.ToString());

}

Is this heading in the right direction?  What would ??????? be?

Thanks, Andrew

something like this:

public void Test1()
{
 Document doc = Application.DocumentManager.MdiActiveDocument;
 doc.LispEnded += new System.EventHandler(OnLispEnded);
}

private void OnLispEnded(object sender, System.EventArgs e)
{
}
