how to compile C function inside C-Sharp program?

Hi,

I do not know how to code in C Sharp. I want to add a C function to an existing, working C Sharp program, and compile it. Let's say the C function is something like this:

Code:

---


#include "stdio.h"
#include "stdlib.h"
#include "string.h"



Test_Function ( )

{

  /* C codes go here. */

}

---

What do I need to do to make this C Sharp program compile with the above test C function added? I tried adding standard C libraries at the top of the C Sharp program, but it won't compile.



Please help. Thank you.

You can't. You can compile your C function into a .dll and then call the function from inside C#, although you're probably better off just learning C#. What's the function you're trying to implement?

Thanks for your response. I have only a week to get this done. Learning to write in C-Sharp at this moment is not practical.
You mentioned about compiling into a .dll and then calling it from C#. Is this the easiest solution? If so, how do you go about doing this?

Just make a normal DLL, export the functions you want to call from C++, then use the [DllImport] attribute to bring the functions into scope in C#.

See this article: .NET Column: Calling Win32 DLLs in C# with P/Invoke

If learning to write in C# is not practical, I would suggest compiling code into a DLL and interfacing to it from C# is also not particularly practical.

Compiling into a DLL is not necessarily the easiest solution, as it requires particular techniques in C# to access the DLL function, but it is the most practical solution if you don't want to rewrite C code as C#. It does rely on some knowledge of C# though.
