A way How to Compile C library into .Net dll?


Can we compile C library as .Net dll (containing and opening access to all C libs functions) by just compiling cpp project containing code like

extern "C" {
#include <library.h>
}

with /clr:pure argument with VS? (VS10)

Or we should do something more trickey?


Solution

  • I found it is the best to use the old style Managed C++ for this.

    CLR:PURE just wont cut it.

    Example:

    extern "C" int _foo(int bar)
    {
      return bar;
    }
    
    namespace Bar
    {
      public __gc class Foo
      {
      public:
        Foo() {}
    
        static int foo(int bar)
        {
          return _foo(bar);
        }
      };
    };
    

    Compile with: /clr:oldSyntax

    Now you can reference the assebmly, and call Bar.Foo.foo() from .NET.
