[SOLVED]How to Convert between QList<double> and QByteArray

sharethl

may be this example is correct, but the byte array it outputs is 164 bytes, suppose to be 160 bytes.
@QByteArray byteArray;
QDataStream stream(&byteArray, QIODevice::WriteOnly);

QList<double> data;
for(int i=0;i<20; i++){
    data.append(i+0.5);
}
stream << data;@

And how to convert byteArray back to QList<double>?

Thanks

Well, just found it, Share to your guys.

QList<double> to bytearray,
@ QByteArray byteArray;
QDataStream stream(&byteArray, QIODevice::WriteOnly);

    QList<double> data;
    for(int i=0;i<20; i++){
        data.append(i+0.5);
    }
    stream << data;

@

ByteArray back to QList<double>

@QList<double> data;
QDataStream stream(&byteArray, QIODevice::ReadWrite);
stream >> data;@
