代码如下:
#include
using namespace std;
class CUser
{
public:
CUser();
virtual~ CUser();
char* WcharToChar(wchar_t* wc);//宽字节转单字节
wchar_t* CharToWchar(char* c); //单字节转宽字节
void Release();//释放资源
private:
char* m_char;
wchar_t* m_wchar;
};

{

int len= WideCharToMultiByte(CP_ACP,0,wc,wcslen(wc),NULL,0,NULL,NULL);

}

{

int len = MultiByteToWideChar(CP_ACP,0,c,strlen(c),NULL,0);
m_wchar=new wchar_t[len+1];
MultiByteToWideChar(CP_ACP,0,c,strlen(c),m_wchar,len);
m_wchar[len]='';
return m_wchar;
}
void CUser::Release()
{
if(m_char)
{
delete m_char;
m_char=NULL;
}
if(m_wchar)
{
delete m_wchar;
m_wchar=NULL;
}
}
使用的时候非常简单了：
代码如下:
WCHAR* wc=findData.cFileName;
CUser u;
char* c=u.WcharToChar(wc);
cout
