Writing unmanaged C++ DLLs for use in C#

I'm a Linux C++ developer, and I need to write C++ dlls for windows, which is to be used in C# applications.

The problem is importing the DLLs into C#, which I have no idea how to do it. In my friends' project its probable that any kind of unmanaged dll will be used, and I'm charge of doing this :-D

I need to import all objects and functions in the DLL, and my search has led me to nothing more than DllImport and so.

Thanks so much for helps.

You can use C++/CLI as a wrapper for your unmanaged C++.For more info on C++/CLI and what it does you can use this link

Have you thought to keep the Dll's in C++ (port then recompiled under VS.NET) less effort than a C# port.

I have in the past made a shared memory DLL to allow LabVIEW (Windows7) and a Winforms C#.NET appl. to share data storage via this dll.

There are many ways to go about this. You can write a CLR dll in C++ which puts an interface that C# can directly "talk" to. This is a nice option cause you can keep native C++ still and not have all of your code be CLR based.

Do some searches for C++/CLI

You can also use dllimport and friends and create a standard dll.
