You'd have to compile the .c file into a DLL, and then you could use P/Invoke to create a C# binding to it

One way is to use C++/CLI as intermediary between your C and C#

C# -> C++/CLI -> C

other way is to expose your C functions and use P/Invoke in C#.

The first choice (using C++/CLI) is less portable, since, AFAIK, the only C++/CLI compiler available is Visual Studio's – dario_ramos Aug 18 '11 at 16:34

Yes. This is called interop and it can be done in various ways. One of them is called Pinvoke - you create a DLL that exports the function you want to call from c# and pinvoke will take care of the rest. I suggest you read about it in microsoft's docs.
