2.1查找串口

string[] ports = SerialPort.GetPortNames();//获取计算机可用串口
            if (ports.Length > 0)//有可用串口
            {
                comboBoxCOMList.Items.AddRange(ports);//添加到下拉列表
                comboBoxCOMList.SelectedIndex = 0;//默认选择第一项
            }

2.2配置串口参数

            serialPort1.BaudRate = 115200;//波特率115200
            serialPort1.DataBits = 8;
            serialPort1.Parity = Parity.None;
            serialPort1.StopBits = StopBits.One;
            serialPort1.ReceivedBytesThreshold = 1;

2.3寻卡

                string response = "";
                serialPort1.Write(ISO15693Card.COMMAND_WRITE_REG);
                Thread.Sleep(MILLISECOND_IN_SLEEP);
                if (serialPort1.BytesToRead > 0) response = serialPort1.ReadExisting();

                serialPort1.Write(ISO15693Card.COMMAND_SET_AGC);
                Thread.Sleep(MILLISECOND_IN_SLEEP);
                if (serialPort1.BytesToRead > 0) response = serialPort1.ReadExisting();

                serialPort1.Write(ISO15693Card.COMMAND_SET_RECV_MODE);
                Thread.Sleep(MILLISECOND_IN_SLEEP);
                if (serialPort1.BytesToRead > 0) response = serialPort1.ReadExisting();

                serialPort1.Write(ISO15693Card.COMMAND_INVEN_CARD);//寻卡
                Thread.Sleep(MILLISECOND_IN_SLEEP);
                if (serialPort1.BytesToRead > 0) response = serialPort1.ReadExisting();

                List<ISO15693Card> cards = ISO15693CardHandler.InventoryCard(response);

2.4写入和读取

写入:

if (WriteSingleBlock(ISO15693CardHandler.CovertEndian(cards[0].ID), "00", stuffId))
                {
                    this.toolStripStatusLabel2.Text = "写入成功";
                }
                else
                {
                    this.toolStripStatusLabel2.Text = "写入失败";

读取:

ID = ReadSingleBlock(ISO15693CardHandler.CovertEndian(cards[0].ID), "00");

2.5用户提示

                        try
                        {
                            int res = cmd.ExecuteNonQuery();

                            // 根据返回值判断是否插入成功
                            if (res != 0)
                            {
                                this.toolStripStatusLabel2.Text = "打卡成功";
                                id = ID;
                            }
                            else
                            {
                                this.toolStripStatusLabel2.Text = "打卡失败";
                            }
                            sqlConn.Close();
                        }
                        catch(Exception ex)
                        {
                            this.toolStripStatusLabel1.Text = "打卡失败" + ex.Message;
                            this.toolStripStatusLabel2.Text = "";
                        }
                    }
                        else
                    {
                        this.toolStripStatusLabel1.Text ="请不重复打卡";
                        this.toolStripStatusLabel2.Text = "";
                    }
                    }
                    else
                    {
                        this.toolStripStatusLabel2.Text = "";
                        this.toolStripStatusLabel1.Text = "";
                    }
