菜鸟求助
本人刚学习ｃ＃对ｃａｄ的ActiveX Automation技术开发！想通过wenjian.Utility.GetEntity(out ReturnObj, out pickPoint, pickPrompt);获得ｃａｄ中的对象（ｗｅｎｊｉａｎ是定义的ｄｕｃｏｍｅｎｔ对象），出现未处理 System.Runtime.InteropServices.COMException

及其在工程中的应用，感觉和上面的例子一样的，代码成功的生成，就是无法调用com组件啊！
高手们请帮帮吧 --------------------编程问答-------------------- 是不是没添加com组件的引用啊？？ --------------------编程问答-------------------- 已经加了！
错误帮助器指示是库函数的错误！
不知怎解决啊！
补充：.NET技术 , C#
