最近在C++編程中經常遇到需要多字節字符與寬字節字符相互轉換的問題，一直自己貼那幾句代碼。覺得麻煩，于是就自己寫了一個類來封裝wchar_t與char類型間的轉換，其他的，諸如：CString/ LPWSTR/TCHAR CHAR/LPSTR之間也是一樣用
#include
using namespace std;
class CUser
{
public:
CUser();
virtual~ CUser();
char* WcharToChar(wchar_t* wc);//寬字節轉單字節
wchar_t* CharToWchar(char* c); //單字節轉寬字節
void Release();//釋放資源
private:
char* m_char;
wchar_t* m_wchar;
};
/////////////////////////////////////////////////////////////////////////////////////
/*字符類型 wchar_t char
/*獲取字符長度 wcslen() strlen()
/*連接兩個字符串 wcscat() strcpy()
/*復制字符串 wcscpy() strcpy()
/*比較兩個字符串 wcscmp() strcmp()
/*具體參數詳見www.linuxidc.com*/
////////////////////////////////////////////////////////////////////////////////////
CUser::CUser()
:m_char(NULL)
,m_wchar(NULL)
{
}
CUser::~CUser()
{
Release();
}
char* CUser::WcharToChar(wchar_t* wc)
{
Release();
int len= WideCharToMultiByte(CP_ACP,0,wc,wcslen(wc),NULL,0,NULL,NULL);
m_char=new char[len+1];
WideCharToMultiByte(CP_ACP,0,wc,wcslen(wc),m_char,len,NULL,NULL);
m_char[len]='/0';
return m_char;
}
wchar_t* CUser::CharToWchar(char* c)
{
Release();
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]='/0';
return m_wchar;
}
void CUser::Release()
{
if(m_char)
{
delete m_char;
m_char=NULL;
}
if(m_wchar)
{
delete m_wchar;
m_wchar=NULL;
}
}
使用的時候非常簡單了：
?
?
WCHAR* wc=findData.cFileName;
CUser u;
char* c=u.WcharToChar(wc);
cout CUser u;
char* pBuffer=u.WcharToChar(szFullPath);
cout
