我们使用IC读卡器时，一般可分为手动读卡和自动监听读卡两种方式。

其中手动读卡根据IC设备厂商提供的Demo修改一下便可实现，相对简单，本文不做过多介绍。

而自动监听读卡，看起来效果要好的多，用户使用起来也要方便一下。其实现的逻辑大家应该都知道，就是通过开一个多线程来轮训IC卡读卡的结果，下面就详细讲一下具体开发过程。（注：本文的读卡器型号为URF-R330，其他设备原理相同）

建立读卡器SDK引用包，如果有不明白的，可以到设备官网或百度下载设备接口的文档，直接上代码 /// /// common 的摘要说明。 /// public class common { public common() { } public int icdev; // 通讯设备标识符 [DllImport("mwrf32.dll", EntryPoint = "rf_init", SetLastError = true, CharSet = CharSet.Auto, ExactSpelling = false, CallingConvention = CallingConvention.StdCall)] //说明：初始化串口通讯接口 public static extern int rf_init(Int16 port, int baud);

建立多线程方式下读卡类，就是根据上面的SDK封装成可直接使用的多线程读卡类，具体功能请参考代码的注释。 /* *作者：** *时间：2018年6月21日 *说明：多线程方式轮训读取IC卡 *注意：次类只包含IC设备操作内容，具体使用需要参考具体页面（FrmHYK） */ /// /// IC多线程读卡 /// public static class ICTool_Thread { /// /// 通讯设备标识符 /// public static int icdev;

在页面添加多线程处理 ①增加变量 Thread t; ②FormLoad事件 private void FormXXXX_Load(object sender, EventArgs e) { System.Windows.Forms.Control.CheckForIllegalCrossThreadCalls = false; ICTool_Thread.initEquipment();//初始化IC设备 ICTool_Thread.cardNumberReciver = this.txt_XFKH;//设置接受卡号的控件 t = new Thread(new ThreadStart(readCard));//初始化线程 t.Start();//开启线程 }

/// /// 线程方法 /// void readCard() { ICTool_Thread.readCard(2); } ③FormClosed事件 //关闭线程计时器 private void FormXXXX_FormClosed(object sender, FormClosedEventArgs e) { t.Abort(); ICTool_Thread.disposeEquipment(); }

搞定收工，调试运行便可直接数卡读数了
