Can you include C++ snippets in C#?

Question

Can I include sections of code written in Visual C++ in my C# app, or vise-versa? I know that you can do that in Objective-C, so I wanted to know if it was possible in C# (.NET 4.0).

Answer 1

Sort of. You can't include them directly in C#, but you can use C# and C++/CLI together, and most C++ can also be compiled as C++/CLI.

Answer 2

Do you have C++ DLLs? If so, you can call C++ DLLs from within C#. There are a few questions on StackOverflow that discuss similar topics:

DllImport can be used to indicate the unmanaged code you want to call.

Answer 3

Not directly. You can create a DLL from C++ code and call said code from C#, though.

See: Forum thread on related topic, and an introduction to managed C++. There's also an example of mixing C++ / C# here, although it uses the command line to build the code.
