How can I use C code in a C# Project? Wrapper class?

Question

I have a C code and I want to use this in C#.

Is there a possibillity except rewriting this code?

Answer 1

Here i got a great tool ,SWIG , can do that. which support a lot of different language, include C# and java.

Answer 2

Build the C code as a DLL, and then use "P/Invoke" to call it. You'll need to learn a bit about interop, which is an area I don't know very much about, I'm afraid – but here are a few links:

• A rather old article, but it looks fairly good
• BCL Team Blog talking about the P/Invoke Interop Assistant
• A recent MSDN Magazine article
• The MSDN interop guide
