从windows注册表中以wstring形式获取REG_DWORD

#include <iostream>
#include <Windows.h>
#include <string>

int main() {
    HKEY hKey;
    DWORD value;
    DWORD valueType;
    WCHAR buffer[256];
    DWORD bufferSize = sizeof(buffer);

    // 打开注册表键
    if (RegOpenKeyEx(HKEY_CURRENT_USER, L"Software\\MyApp", 0, KEY_READ, &hKey) == ERROR_SUCCESS) {
        // 获取注册表键的值
        if (RegQueryValueEx(hKey, L"MyValue", NULL, &valueType, reinterpret_cast<LPBYTE>(&value), &bufferSize) == ERROR_SUCCESS) {
            // 检查值的数据类型是否为REG_DWORD
            if (valueType == REG_DWORD) {
                // 将DWORD类型的值转换为wstring
                std::wstring valueString = std::to_wstring(value);
                std::wcout << L"获取到的值为：" << valueString << std::endl;
            }
        }

        RegCloseKey(hKey);
    }

    return 0;
