            // 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);

推荐答案

您是否已将数据加载到HexViewer？你应该注意确认中断/分隔符是CR，NL还是CR + NL字符。扫描仪可能与运行代码的设备/ PC不同，因此 Environment.NewLine 可能不匹配。

Have you loaded the data into a HexViewer? You heed to confirm if the break/seperator is a CR, NL, or CR+NL character(s). The scanner may not be using the same as the device/PC running your code, so Environment.NewLine may be a mismatch.
