Look for articles about pinvoke or p/invoke as well as interop services.

HI,
If your are using VisualStudio, it's easy to communicate Interop Service. Add Ref. to that dll by right click. Then a wrapper class will be created automatically . This will do your interop service activities.

Thanks Sam: dll having unmanaged code, is it possible that it is consumed using interop services?

Mahesh: You will need the documentation of how the DLLs are called. If you have documentation and/or sample programs showing how to use the DLLs using C or C++ then you probably can use the DLLs in C#. Do you have the documentation?

Naveen: A DLL can have an entry point; see DllMain Entry Point. A C# library project application exists as a DLL (I think) when built and it must be called using managed code as an object, not as a regular DLL. I assume that Mahesh is asking about a regular DLL; a DLL that has unmanaged code. C# cannot create code for a DLL with unmanarged code.

dll(Dynamic Linking Library) are assembly without entry point, it can be written in C,C++,c# etc , you can use it in in C# , Add reference of the dll in the solution explorer.
