C# is ideally suited to calling in to "C" functions. One way is to create an C adapter to the C++ functionality:

Step 1: Expose a C function from the DLL:

extern "C" __declspec(dllexport) int someMethod(int paramA);

Step 2: Import in to C#

[DllImport("your.dll", EntryPoint="someMethod")]
public static extern UInt32 NiceNameFunc(UInt32 paramA);

Assuming you want calling native DLL (C++/libs) called from managed (C#) code:

  • make sure your functions are exported form the DLL
  • use whatever favorite linker to link Libs to DLL.
  • create C# class with methods annotated with DllImport
  • make sure your C# project is set for same bitness (x86/x64) as native DLL

If you want compile C++ Libs to managed DLL (assembly) - you can't do that. You may be able to use managed C++ to compile sources to a assembly.
