关于从C＃到C ++ DLL项目访问COM对象 [英] About accessing COM objects from C# to C++ dll project

问题描述

我在c＃应用程序中工作。我通过C ++ DLL项目的包装器使用了一些方法。

I am working in c# application. I have used some method through wrapper from C++ dll project.

我想将数据作为参数传递给c＃到C ++ dll的包装器方法。

I want to pass data as an argument to wrapper methods from c# to C++ dll.

这个问题可能有两种方法。

there may be two ways for this issue.

1）以基本数据类型作为参数发送数据，2）发送COM对象作为参数。

1)send data in basic data types as arguments and 2) send COM object as argument.

目前，我在C＃中使用COM对象。那么，请告诉我如何在C ++ DLL中使用COM对象？

currently, I am using COM objects in C#.So, Please tell me how to use COM object in C++ dll?

提前致谢。
