The following code I am using to find the number of read bytes from QFile. With some files it gives the correct file size, but with some files it gives me a value that is approximatively fileCSV.size()/2. I am sending two files that have same number of characters in it, but have different file sizes link text. Should i use some other objects for reading the QFile?
QFile fileCSV("someFile.txt");
if ( !fileCSV.open(QIODevice::ReadOnly | QIODevice::Text))
emit errorOccurredReadingCSV(this);
QTextStream textStreamCSV( &fileCSV ); // use a text stream
int fileCSVSize = fileCSV.size());
qint64 reconstructedCSVFileSize = 0;
while ( !textStreamCSV.atEnd() )
{
QString line = textStreamCSV.readLine(); // line of text excluding '\n'
if (!line.isEmpty())
{
reconstructedCSVFileSize += line.size(); //this doesn't work always
reconstructedCSVFileSize += 2;
}
else
reconstructedCSVFileSize += 2;
}
I know that reading the size of QString is wrong, give me some other solutions if you can.
Thank you.
