参考博客：

QT5修改windows电脑IP地址_fangye945a的博客-CSDN博客_qt 修改ip

1、创建一个QWidget项目，更改UI界面为

2、.pro中加上：

QT       += network

QT       += networkgreaterThan(QT_MAJOR_VERSION, 4): QT += widgetsTARGET = ChangeIP
TEMPLATE = app# The following define makes your compiler emit warnings if you use
# any feature of Qt which has been marked as deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS# You can also make your code fail to compile if you use deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0SOURCES += \main.cpp \mainwindow.cppHEADERS += \mainwindow.hFORMS += \mainwindow.ui

3、.h

#ifndef MAINWINDOW_H
#define MAINWINDOW_H#include <QMainWindow>namespace Ui {
class MainWindow;
}class MainWindow : public QMainWindow
{Q_OBJECTpublic:explicit MainWindow(QWidget *parent = 0);~MainWindow();private slots:void on_showIPButton_clicked();void on_changeIPButton_clicked();private:Ui::MainWindow *ui;
};#endif // MAINWINDOW_H

4、.cpp

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QProcess>
#include <QDebug>
#include <QHostAddress>
#include <QNetworkInterface>MainWindow::MainWindow(QWidget *parent) :QMainWindow(parent),ui(new Ui::MainWindow)
{ui->setupUi(this);
}MainWindow::~MainWindow()
{delete ui;
}void MainWindow::on_showIPButton_clicked()
{QList<QNetworkInterface> network = QNetworkInterface::allInterfaces();    // 获取所有的接口foreach(QNetworkInterface net, network){QString netName = net.humanReadableName();  // 获取网络名称QList<QNetworkAddressEntry> list = net.addressEntries();  // 获取IP地址与子网掩码等foreach(QNetworkAddressEntry address,list){if(address.ip().protocol() == QAbstractSocket::IPv4Protocol)  // 获取IPv4的地址{qDebug() << "网卡名："<< netName<< " IPv4：" << address.ip().toString()<< " 子网掩码：" << address.netmask().toString();}}}
}void MainWindow::on_changeIPButton_clicked()
{//netsh interface ip set address \"以太网\" static 192.168.10.4 255.255.255.0 192.168.10.1QProcess *process = new QProcess();QString cmd = "netsh interface ip set address ";cmd += "\"";     //网卡名称要加双引号cmd += ui->networkNameEdit->text();cmd += "\" ";cmd += "static ";cmd += ui->ipEdit->text(); //IPcmd += " ";cmd += ui->netmaskEdit->text(); //子网掩码cmd += " ";cmd += ui->gatewayEdit->text(); //网关qDebug()<< "cmd = " << cmd;process->start(cmd);   //执行dos命令process->waitForFinished(); //等待执行完成delete process;
