c# - Attach event to dynamic object

I create a c# dynamic object of a COM-Object on the fallowing way:

dynamic pdfCreator = Activator.CreateInstance(
                       Type.GetTypeFromProgID("PDFCreator.clsPDFCreator"));

The class clsPDFCreator is defining an event calling eReady. But when I try to register an Eventhandler like

pdfCreator.eReady += _PDFCreator_eReady;

I get the error message "Operator '+=' cannot be applied to operands of type 'dynamic' and 'method group'".

How can i register an EventHandler to an Event which is declared of a dynamic object?

Since the delegate type is not known at compile time, you have to specify it. The Action delegate matches methods with no parameters or return value:

pdfCreator.eReady += new Action(_PDFCreator_eReady);
