C# – tool to convert ANSI C code to C#


I need to import some ANSI C code into a project I'm working on. For reasons I prefer not to go into, I want to refactor the code to C# rather than trying to wrap the original code. It will take me perhaps a couple of days to do the work by hand, but before I start, is there an automated tool that can get me most of the way there? I'm a cheapskate and the work I'm doing is pro bono, so free tools only please.

Best Solution

If manual refactoring is "only" going to take a few days, that would get my vote. Depending on what the C code is doing and how it is written (pointers, custom libraries, etc.) an automated converter may just make a mess. And untangling that mess could be a larger task than just converting by hand.
