CreateDelegate error

[Max]

Hello,

I'm using late binding to automate to multiple versions of MS Outlook and I'm getting an ArgumentException when I create a delegate.

System.ArgumentException: Error binding to target method.
at System.Delegate.InternalCreate(Object target, String method, Boolean ignoreCase)
at System.Delegate.CreateDelegate(Type type, Object target, String method)

and it happens on the last line of this code:

Type oType = Type.GetTypeFromProgID("Outlook.Application");
oApp = Activator.CreateInstance(oType);
 
oInspectors = oApp.GetType().GetProperty("Inspectors").GetValue(oApp, null);
 
e_NewInspector = oInspectors.GetType().GetEvent("NewInspector");
d_NewEventDelegate = Delegate.CreateDelegate(e_NewInspector.EventHandlerType,
this, "Inspectors_NewInspector");
 

The class that is supposed to handle the event is defined as follows:

private void Inspectors_NewInspector(object insp, System.IntPtr param){ .... }
 

The debugger loads the assemblies from the GAC:
Loaded 'c:\windows\assembly\gac\microsoft.office.interop. outlook\11.0.0.0__71e9bce111e9429c\microsoft.offic e.interop.outlook.dll',
No symbols loaded.
Loaded 'c:\windows\assembly\gac\office\11.0.0.0__71e9bce1 11e9429c\office.dll', No symbols loaded.

Can someone tell me what I'm doing wrong?
