        List<char> _barcode = new List<char>(10);
        public Form1()
        {
            InitializeComponent();

        }

        private void Form1_KeyPress(object sender, KeyPressEventArgs e)
        {
            TimeSpan elapsed = (DateTime.Now - _lastKeystroke);
            if (elapsed.TotalMilliseconds > 100)
                _barcode.Clear();

            // record keystroke & timestamp
            _barcode.Add(e.KeyChar);
            _lastKeystroke = DateTime.Now;

            // process barcode
            if (e.KeyChar == 13 && _barcode.Count > 0)
            {

                    string msg = new String(_barcode.ToArray());

                string[] lines = msg.Split(new string[] { Environment.NewLine }, StringSplitOptions.None);

                if (lines.Length > 5)
                {
                    string msg1 = lines[1].Substring(lines[1].IndexOf(":") + 1);
                    label3.Text = msg1;
                    string msg2 = lines[2].Substring(lines[2].IndexOf(":") + 1);
                    label4.Text = msg2;
                    string msg3 = lines[3].Substring(lines[3].IndexOf(":") + 1);
                    label5.Text = msg3;
                    string msg4 = lines[4].Substring(lines[4].IndexOf(":") + 1);
                    label6.Text = msg4;
                    label2.Text = lines[5].Substring(lines[5].IndexOf(":") + 1);
                }
                    _barcode.Clear();
            }
        }
    }
}

msg variable in debug have values of scanning qr code

but problem now

How to split them to lines as above ?

I would recommend that you create a console test app with a hardcoded 'sample' barcode string so you can step through and debug your code in order to get your parsing code working.

That being said, is the barcode format exactly what you have posted above? If so, I'm counting 9 lines of data, not 5 (assuming the first line begins with "30 General..."). When you split, each line will be returned in the array even if the line is empty. You can change this behavior by specifying a different StringSplitOptions value other than None.
