推荐答案

如何使用QStringList代替QList<QString>-

QStringList numberList_;    // instead of QList<QString>, use this
QString myString1 = "Hello";
QString myString2 = "World";
numberList_ << myString1;
numberList_ << myString2;

QByteArray byteArray;
QBuffer buffer(&byteArray);
QDataStream out(&buffer);
out << numberList_;

也许QList<QString>也应该代替QStringList.如果不行，那么您可以轻松地将其转换为QStringList.

Probably QList<QString> should also work in place of QStringList. If it doesn't, well, you can convert it pretty easily to QStringList.
