将事件附加到动态对象 [英] Attach event to dynamic object

问题描述

我以休闲方式创建了一个 COM 对象的 c# 动态对象:

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

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

类 clsPDFCreator 正在定义一个调用 eReady 的事件.但是当我尝试注册一个像

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

pdfCreator.eReady += _PDFCreator_eReady;

我收到错误消息运算符‘+=’不能应用于‘动态’和‘方法组’类型的操作数".

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

如何将 EventHandler 注册到声明为动态对象的 Event?

推荐答案

这个怎么样:

public delegate void eReadyHandler();

static void Main(string[] args)
{
    var comType = Type.GetTypeFromProgID("PDFCreator.clsPDFCreator");
    dynamic pdfCreator = Activator.CreateInstance(comType);
    //dynamic pdfCreator = new PDFCreator.clsPDFCreator();

    //pdfCreator.eReady = null;
    pdfCreator.eReady += new eReadyHandler(_PDFCreator_eReady);
}

public static void _PDFCreator_eReady()
{

}
