Calling a C Function from CSharp

[Guest]

Is there someone who can tell me how to call a piece of legacy code written in C from a CSharp program? I downloaded Eric Gunnerson's stuff and it doesn't work

I want to reuse a string manipulator which was written in C in ancient times to operate on some strings I am reading with a C# program I'm working on now.

Use PInvoke, MC++, or wrap the lagacy code within a COM component.
The MSDN contains tons of information on these topics.

Well if it is a routine in a DLL you can use the [DLLImport("mydll.dll")] attribute on a method that defines that routine

Or you can port it
