Hello Mohaammed,
var qrText = textBox1.Text + "\n" +
    textBox2.Text + "\n" +
    textBox3.Text + "\n" +
    textBox4.Text + "\n" +
    textBox5.Text;

pictureBox1.Image = qrcode.Draw(qrText, 50);
You can decode the QR code and assigning the data to the different textboxes again.
var bitmap = new Bitmap(pictureBox1.Image);
var lumianceSsource = new BitmapLuminanceSource(bitmap);
var binBitmap = new BinaryBitmap(new HybridBinarizer(source));
var reader = new MultiFormatReader();
Result result = null;
try
{
    result = reader.Decode(binBitmap);
}
catch (Exception err)
{
    // Handle the exceptions, in a way that fits to your application.
}
var resultDataArray = result.Text.Split(new char[] {'\n'});
// Only if there were 5 linebreaks to split the result string, it was a valid QR code.
if (resultDataArray.length == 5)
{
    textBox1.Text = resultDataArray[0];
    textBox2.Text = resultDataArray[1];
    textBox3.Text = resultDataArray[2];
    textBox4.Text = resultDataArray[3];
    textBox5.Text = resultDataArray[4];
}
