在C＃项目中使用COM dll

Question

I have all COM dll generated from a C++ library project. I want to use it in my C# project. I guess, I should import the xxxLib.dll file from the C++ library project, and import it to my C# project. But this xxxLib.dll is not generated in my C++ project. But I could see that xxx.dll and xxx.tlb are generated

Answer 1

You just register the dll with regsvr32 .

Then add a reference, go to the COM tab, and choose your COM dll.
