      strSentence = strSentence + char(13) + char(10);//得到的是一行
      char temp[128] = {0};

     int wcsLen = ::MultiByteToWideChar(CP_UTF8, NULL, temp, strlen(temp), NULL, 0);
     //分配空間要給'\0'留個(gè)空間，MultiByteToWideChar不會(huì)給'\0'空間
     wchar_t* wszString = new wchar_t[wcsLen + 1];
     //轉(zhuǎn)換
     ::MultiByteToWideChar(CP_UTF8, NULL, temp, strlen(temp), wszString, wcsLen);
     //最后加上'\0'
     wszString[wcsLen] = '\0';
    
     int ansiLen = ::WideCharToMultiByte(CP_ACP, NULL, wszString, wcslen(wszString), NULL, 0, NULL, NULL);
     //同上，分配空間要給'\0'留個(gè)空間
     char* szAnsi = new char[ansiLen + 1];
     //轉(zhuǎn)換
     //unicode版對應(yīng)的strlen是wcslen
     ::WideCharToMultiByte(CP_ACP, NULL, wszString, wcslen(wszString), szAnsi, ansiLen, NULL, NULL);
     //最后加上'\0'
     szAnsi[ansiLen] = '\0';

    ............szAnsi就是最終的結(jié)果

     if(wszString)
     {
      delete []wszString;
      wszString = NULL;
     }

    
     if (szAnsi)
     {
      delete []szAnsi;
      szAnsi = NULL;
     }
   }

}
但在VC8.0下，就不一樣了。如果用CString來做ReadString的參數(shù)，始終得不到ASCII字符，因?yàn)閂C8下默認(rèn)的就是寬字符，而UTF-8就是寬字符，所以必須用char*來做ReadString的參數(shù)，然后在用函數(shù)MultiByteToWideChar轉(zhuǎn)成UNICODE。如果想得到一行數(shù)據(jù)，就找標(biāo)記\r\n就可以
