Qt读写配置文件

Qt读写配置文件system.ini

头文件的实现

config.h

#ifndef CONFIG_H
#define CONFIG_H

#include <QVariant>
#include <QSettings>

class Config
{

public:
	Config(QString qstrfilename = "");
	virtual ~Config(void);
	void Set(QString, QString, QVariant);
	QVariant Get(QString, QString);

private:
	QString m_qstrFileName;
	QSettings *m_psetting;
};

#endif

源文件的实现

UtilsConfig.cpp

#include "config.h"
#include <QtCore/QtCore>
#include <QDebug>

Config::Config(QString qstrfilename)
{
	if (qstrfilename.isEmpty())
	{
		//ini文件放在源文件目录
		m_qstrFileName = "./sysConfig.ini";
	}
	else
	{
		m_qstrFileName = qstrfilename;
	}

	m_psetting = new QSettings(m_qstrFileName, QSettings::IniFormat);
	qDebug() << m_qstrFileName;
}

Config::~Config()
{
	delete m_psetting;
	m_psetting = 0;
}

void Config::Set(QString qstrnodename, QString qstrkeyname, QVariant qvarvalue)
{
	m_psetting->setValue(QString("/%1/%2").arg(qstrnodename).arg(qstrkeyname), qvarvalue);
}

QVariant Config::Get(QString qstrnodename, QString qstrkeyname)
{
	QVariant qvar = m_psetting->value(QString("/%1/%2").arg(qstrnodename).arg(qstrkeyname));
	return qvar;
}

sysConfig.ini文件位置及内容

文件位置：与main.cpp等文件在同一个目录

文件内容：

[REMOTE_TCP]
IP=172.18.101.124
PORT=6666

[LOCAL_UDP]
PORT=8888

项目源文件使用

主要代码

// 获取配置文件的值
QString TCP_IP = Config().Get("REMOTE_TCP", "IP").toString();
QString TCP_PORT = Config().Get("REMOTE_TCP", "PORT").toString();
QString UDP_PORT = Config().Get("LOCAL_UDP", "PORT").toString();

// 设置配置文件的值
QString m_strTcpIp = "xx.xx.xx.xx";
QString m_strTcpPort = "xx";
QString m_strUdpPort = "xxx";
Config().Set("REMOTE_TCP", "IP", m_strTcpIp);
Config().Set("REMOTE_TCP", "PORT", m_strTcpPort);
Config().Set("LOCAL_UDP", "PORT", m_strUdpPort);
