格式powershell输出至最低

Question

我正在从QProcess中调用PowerShell

    QProcess p;

    p.start("powershell.exe", QStringList() << "get-wmiobject win32_networkadapter -filter 'netconnectionstatus = 2' | select netconnectionid");

    if (p.waitForFinished())
        while(p.canReadLine())
        {
            auto line = QString::fromStdString(p.readLine().toStdString());
            qDebug() << line;
        }

，从QTCreator输出中，我

"\r\n"
"\r\n"
"netconnectionid : Ethernet\r\n"
"\r\n"
"netconnectionid : VirtualBox Host-Only Network\r\n"
"\r\n"
"\r\n"
"\r\n"

想将PowerShell输出降低到

"Ethernet"
"VirtualBox Host-Only Network"

如何将PowerShell输出格式化为最小值？
