读取数组值 C++/CLI

  • 772
DWORD dwType = REG_SZ;
HKEY hKey = 0;
String^ value;
DWORD value_length = 1024;
RegOpenKey(HKEY_CURRENT_USER, _T("Software\\Valve\\Steam"), &hKey);
RegQueryValueEx(hKey, _T("Language"), NULL, &dwType, (LPBYTE)&value, &value_length);

下午好，问题是，为什么这段代码不行，敲出错误？请帮忙。如果是这样，则需要返回值String^

    稍微调整一下您的解决方案。像这样尝试

        DWORD dwType = REG_SZ;
    HKEY hKey = 0;
    String^ value;
    DWORD bufSize = 1024;
    LPVOID buf = new char[bufSize];
    RegOpenKey(HKEY_CURRENT_USER, L"Software\\Valve\\Steam", &hKey);
    RegQueryValueEx(hKey, L"Language", NULL, &dwType, (BYTE*)buf, &bufSize);
    WCHAR *wch = reinterpret_cast<WCHAR *>(buf);
    value = gcnew String(wch);
