I need to convert a QString
which is
already in hexadecimal format to a QByteArray
. For example:
QString a = "AF5603B4"
Should be stored in QByteArray
as:
QByteArray ba[4] = { 0xAF, 0x56, 0x03, 0xB4 }
How do I do this in Qt 5.9? I have tried using many methods but all of these convert the string characters to their ASCII values and then give that hexadecimal value.
I found Convert.toByte
method to use in C# ; is there an equivalent in Qt I can use?
You can use
ByteArray::fromHex
function like this:Output:
And to convert QByteArray to Hex string:
