连接到C＃中的COM事件 - 支持受管和非受管服务器

本文介绍了连接到C＃中的COM事件 - 支持受管和非受管服务器的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我正在编写需要连接到COM事件的C＃代码。我实现了使用 IConnectionPointContainer和IConnectionPoint，因此：I'm writing C# code that needs to connect to COM events. I implemented the use ofIConnectionPointContainer and IConnectionPoint thus: IConnectionPointContainer connectionPointContainer = internalGenerator as IConnectionPointContainer; if (connectionPointContainer == null) { Debug.Fail("The script generator doesn't support the required interface - IConnectionPointContainer"); throw new InvalidCastException("The script generator doesn't support the required interface - IConnectionPointContainer"); } Guid IID_IScriptGeneratorEvents = typeof(IScriptGeneratorCallback).GUID; connectionPointContainer.FindConnectionPoint(ref IID_IScriptGeneratorEvents, out m_connectionPoint); m_connectionPoint.Advise(this, out m_cookie); $ bThe problem is that when the COM server is actually implemented in .Net (say, C#), after .Net creates it, it handles it as a .Net object, not a COM object. Since the .Net object doesn't implement the IConnectionPointContainer interface, I get null when trying to cast the object to that interface.任何想法如何解决这个问题？ 我当然可以在C＃COM服务器中实现IConnectionPointContainer，但是我想要一个更简单的解决方案，我可以很容易地解释给需要实现COM服务器的其他开发人员。Any idea how can i workaround this?I can of course implement IConnectionPointContainer by myself in the C# COM server, however I would like a simpler solution, which I can easily explain to other developers which need to implement the COM server. PS我必须使用IConnectionPointContainer作为COM服务器可以在非.NET（C ++，Java）中实现。P.S I must use IConnectionPointContainer as the COM server may be implemented in non-.Net (C++, Java).谢谢， InbarThanks,Inbar推荐答案我没有找到办法。 最后，我将在.Net中定义另一个接口，并将编写2个代码路径，一个用于.Net对象，一个用于真正的COM对象。I didn't find a way to do this.Eventually I will define another interface in .Net and will write 2 code paths, one for .Net objects and one for real COM objects. 这篇关于连接到C＃中的COM事件 - 支持受管和非受管服务器的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
