Convert a QByteArray to a QVariantList

[franco.amato]

Qt isn't syntactically different in C#; it is written and works exactly the same way as it does anywhere else.

It isn't the language that's at fault.

OK so let me know why this code doesn't work:

//fp data
QByteArray b = user->fingerData(); //<-- return a reference to a QByteArray containing the fingerprint data
 
QVariant v(b);
QVariantList fingerData;
 
fingerData.append(v);

//fp data
QByteArray b = user->fingerData(); //<-- return a reference to a QByteArray containing the fingerprint data

QVariant v(b);
QVariantList fingerData;

fingerData.append(v);

To copy to clipboard, switch view to plain text mode 

I need to convert QByteArray b to QVariantList fingerData.
I'm sure I'm doing some mistake but I don't know which one. Instead in C# I don't have to convert anything.
I prefere C++ to C# but I can not loose 1 week to discover how to do a conversion.

What do you mean by "it doesn't work"? It doesn't compile, it crashes when ran?

Instead in C# I don't have to convert anything.

If you were using Qt bindings in C# to access the COM server you'd have to do the exact same conversion. Don't blame the language, as somebody already said. You are using Qt wrapper over C++ (or probably even C) interface to (D)COM. If you have trouble using Qt structures with COM, maybe you should make a bare C/C++ WinAPI call to the COM server. You will probably get some wacky structure in return but maybe this structure will be documented by MSDN good enough for you to understand how to use it.
