Find programmatically if under C++ or C++/CLI

问题

I would like my C++/CLI headers to compile even when under another platform. Of course I am not expecting to compile them but just ignore them.

Would this be appropriate ? (_MSC_VER)

#ifdef _MSC_VER

    using namespace System;

        namespace ENMFP {

            public ref struct Data {
            };
        }

#endif

Thanks !

You can use the __cplusplus_cli predefined macro documented here:

#ifdef __cplusplus_cli

using namespace System;

namespace ENMFP
{
    public ref struct Data
    {
        // ...
    };
}

#endif  // __cplusplus_cli
