QT实现windows下获取CPU、内存及磁盘信息

一.目的

QT代码实现windows下获取CPU、内存及磁盘信息。

二.代码实现

1.获取CPU和内存信息

   #include <Windows.h>

    // 获取CPU信息

    SYSTEM_INFO systemInfo;

    GetSystemInfo(&systemInfo);

    qDebug() << "CPU Architecture:" << (systemInfo.wProcessorArchitecture == PROCESSOR_ARCHITECTURE_AMD64 ? "AMD64" : "x86");

    qDebug() << "Number of Processors:" << systemInfo.dwNumberOfProcessors;

    // 获取内存信息

    MEMORYSTATUSEX statex;

    statex.dwLength = sizeof (statex);

    GlobalMemoryStatusEx (&statex);

    qDebug() << "Total Physical Memory:" << statex.ullTotalPhys / (1024.0 * 1024.0) << "MB";

qDebug() << "Available Physical Memory:" << statex.ullAvailPhys / (1024.0 * 1024.0) << "MB";

2.获取磁盘信息

#include <QStorageInfo>

//获取当前系统盘的磁盘情况

    QStorageInfo storageInfo = QStorageInfo::root();

    storageInfo.refresh();  // 刷新信息，获取最新的磁盘信息

    qDebug() << "总大小:" << storageInfo.bytesTotal() / (1024 * 1024 * 1024) << "GB";

    qDebug() << "可用空间:" << storageInfo.bytesAvailable() / (1024 * 1024 * 1024) << "GB";

    // 获取指定路径的磁盘情况

    QString path = "D:/"; // 替换为你想查询的磁盘或目录路径

    QList<QStorageInfo> storageInfos = QStorageInfo::mountedVolumes();

    for (const QStorageInfo &storageInfo : storageInfos) {

        if (storageInfo.rootPath() == path) {

            qDebug() << "Total Disk Space:" << storageInfo.bytesTotal() / (1024.0 * 1024.0) << "MB";

            qDebug() << "Available Disk Space:" << storageInfo.bytesAvailable() / (1024.0 * 1024.0) << "MB";

            qDebug() << "Device Name:" << storageInfo.name();

            qDebug() << "File System Type:" << storageInfo.fileSystemType();

            break; // 找到匹配的存储设备后退出循环

        }

    }
