Thread: Can I integrate C and C# code?

you're going to get yelled at for posting the same thing in two threads.

But to answer. you can integrate them by using a C++/CLI module. C++/CLI can do managed and unmanaged code together in an assembly. The C# can then use the C++ assembly almost as if it is C# code

Sorry about posting in two threads. I should have read the guidlines. I was hoping that if the C# programmers didn't have experience in this, maybe the C programmers would.

oh, no prob. Just be glad I got to you first Others throw punches.

I've been using C++/CLI for a couple months now. Many of the people here hate it, but I see it as extremely useful for bringing existing code to .NET.

As Fyb already said, you have to write a dll to integrate your C/C++ code with .NET. You can either write a normal C dll and call it through interop like any other C dll in C#. This is somewhat ugly on the C# side of the program, but you could use the same dll from your C programs. Somewhat nicer from a .NET point of view is writing a managed wrapper, also called a mixed mode dll. C++/CLI compiles to a normal .NET assembly, that looks, behaves and works the same as any dll written in C#. In C++/CLI you can include unmanaged code. Most of the time this is used to bring legacy C code into a new .NET application.
