QUdpSocket 发送数据

问题：标准范式。

方法：

初始化阶段：

QUdpSocket m_udpSocket = new QUdpSocket(this);

m_udpSocket->open(QUdpSocket::WriteOnly);

m_udpSocket->bind(QHostAddress::LocalHost, 10000);

发送数据阶段：

QByteArray testArray;

testArray.clear();

testArray.resize(8);

......

m_UdpSocket->writeDatagram(testArray, QHostAddress::LocalHost, 12345);

关闭连接阶段：

if (m_udpSocket && m_udpSocket->isOpen())

{

    m_udpSocket->close();

    delete m_udpSocket;

    m_udpSocket = nullptr;

}
