首先是c++写的声明文件
测试程序的目录结构
测试代码c#
// Inclusion guard
#ifndef _DLLTUT_DLL_H_
#define _DLLTUT_DLL_H_
// Make our life easier, if DLL_EXPORT is defined in a file then DECLDIR will do an export
// If it is not defined DECLDIR will do an import
#if defined DLL_EXPORT
#define DECLDIR __declspec(dllexport)
#else
#define DECLDIR __declspec(dllimport)
#endif
// Specify "C" linkage to get rid of C++ name mangeling
extern "C"
{
// Declare 2 functions
DECLDIR int Add( int a, int b );
DECLDIR void Function( void );
}
// End the inclusion guard
#endif
#ifndef _DLLTUT_DLL_H_
#define _DLLTUT_DLL_H_
// Make our life easier, if DLL_EXPORT is defined in a file then DECLDIR will do an export
// If it is not defined DECLDIR will do an import
#if defined DLL_EXPORT
#define DECLDIR __declspec(dllexport)
#else
#define DECLDIR __declspec(dllimport)
#endif
// Specify "C" linkage to get rid of C++ name mangeling
extern "C"
{
// Declare 2 functions
DECLDIR int Add( int a, int b );
DECLDIR void Function( void );
}
// End the inclusion guard
#endif
