char temp[128] = {0};

//分配空間要給'\0'留個空間，MultiByteToWideChar不會給'\0'空間
wchar_t* wszString = new wchar_t[wcsLen + 1];
//轉換
::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'留個空間
char* szAnsi = new char[ansiLen + 1];
//轉換
//unicode版對應的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，始終得不到ASCII字符，因為VC8下默認的就是寬字符，而UTF-8就是寬字符，所以必須用char*來做ReadString的參數，然后在用函數MultiByteToWideChar轉成UNICODE。如果想得到一行數據，就找標記\r\n就可以
