asp.net 读取身份证源码

一般来说winform应用程序解决这个问题起来时很容易的，web应用程序就麻烦一点了。 这里我说说我的解决思路： 一、你必要有联机型居民身份证阅读器一个（带驱动光盘），这里我用的是精伦电子公司的iDR200,并有这个阅读器的开发接口说明。 二、新建一个winform控件项目ReadCardControl，添加一个主类ReadCard 1、 声明dll入口 [DllImport("Sdtapi.dll")] private static extern int InitComm(int iPort);//初始化 [DllImport("Sdtapi.dll")] private static extern int Authenticate();//卡认证 [DllImport("Sdtapi.dll")] private static extern int ReadBaseInfos(StringBuilder Name, StringBuilder Gender, StringBuilder Folk, StringBuilder BirthDay, StringBuilder Code, StringBuilder Address, StringBuilder Agency, StringBuilder ExpireStart, StringBuilder ExpireEnd);//读取数据，推荐使用 [DllImport("Sdtapi.dll")] private static extern int CloseComm();//关闭端口 [DllImport("Sdtapi.dll")] private static extern int ReadBaseMsg(byte[] pMsg, ref int len);//读取数据，这里不用 [DllImport("Sdtapi.dll")] private static extern int ReadBaseMsgW(byte[] pMsg, ref int len);//读取数据，这里不用 [DllImport("kernel32.dll")] private static extern int Beep(int dwFreq, int dwDuration);//用来大吼一声 2、读卡方法 private string[] arrys = null;//声明用来保存身份证信息的数组 public void OnTimer() { StringBuilder Name = new StringBuilder(31); StringBuilder Gender = new StringBuilder(3); StringBuilder Folk = new StringBuilder(10); StringBuilder BirthDay = new StringBuilder(9); StringBuilder Code = new StringBuilder(19); StringBuilder Address = new StringBuilder(71); StringBuilder Agency = new StringBuilder(31); StringBuilder ExpireStart = new StringBuilder(9); StringBuilder ExpireEnd = new StringBuilder(9); //int len = 0; //string[] temp; char[] param = { '\0' }; byte[] pMsg = new byte[256]; string[] baseinfo = new string[9]; //打开端口 int intOpenRet = InitComm(1001); if (intOpenRet != 1) { //SetText("阅读机具未连接", lblMsg); return; } //卡认证 int intReadRet = Authenticate(); if (intReadRet != 1) { //SetText("卡认证失败", lblMsg); CloseCo
