直接贴文件如下：

#ifdef  NDEBUG#define assert(_Expression)     ((void)0)#define assertMsg(_Expression, _Msg) ((void)0)#else#include <crtdefs.h>#include "assert.h"#define assert(_Expression) (void)( (!!(_Expression)) || (_wassert(_CRT_WIDE(#_Expression), _CRT_WIDE(__FILE__), __LINE__), 0) )#define assertMsg(_Expression, _Msg) (void)( (!!(_Expression)) || (_wassert(_CRT_WIDE(_Msg), _CRT_WIDE(__FILE__), __LINE__), 0) )#endif

另有一种不太好看的：

assert(a == b && "A is not equal to B");
