1）字符转换函数char *_itoa( int value, char *string, int radix ); char *_i64toa( __int64 value, char *string, int radix ); char * _ui64toa( unsigned _int64 value, char *string, int radix ); wchar_t * _itow( int value, wchar_t *string, int radix ); wchar_t * _i64tow( __int64 value, wchar_t *string, int radix ); wchar_t * _ui64tow( unsigned __int64 value, wchar_t *string, int radix ); double atof( const char *string ); int atoi( const char *string ); __int64 _atoi64( const char *string ); long atol( const char *string ); int sprintf( char *buffer, const char *format [, argument] ... ); int swprintf( wchar_t *buffer, const wchar_t *format [, argument] ... ); void CString::Format( LPCTSTR lpszFormat, ... ); void CString::Format( UINT nFormatID, ... ); 其他方法：可以用CString类的Format()方法，具体实现如下： int i = 2008; CString str; str.Format("%d", i); 这样就OK了。 函数解析： CString::Format void Format( LPCTSTR lpszFormat, ... ); void Format( UINT nFormatID, ... );
