德卡T10读卡器 读取身份证号码和身份证UID

这个简单的测试项目，界面上有个timer控件，设计的是3秒执行一下读取身份证的动作，目前想到的是这种循环方式，德卡T10这个机子，身份证放上去，不会自动去执行读取的操作。

1.界面

2.界面的代码 Form1.cs 如下

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Threading;

namespace IDCard
{
    public partial class Form1 : Form
    {
        public static string StrCardNo = "1";   //记录下的 上次有效的身份证号
        public Form1()
        {
            InitializeComponent();
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            textBox8.Focus();
            PersonInfo person = new PersonInfo();
            int result = IDCard.GetCardInfo.getCardInfo(ref person);
            if (result < 0)//未读取到身份证
            {
                return;
            }
            string strCardNoThis="";    //本次读取到的身份证号
            if (person.IdNumber == null)
            {
                strCardNoThis = "";
            }
            else
            {
                strCardNoThis = person.IdNumber;
                //如果记录的上次的有效号和 本次的号 一样，处理掉 不用
                if (StrCardNo.Equals(strCardNoThis))
                {
                    return;
                }
                else  //如果和之前的不一样，赋值为最新
                {
                    StrCardNo = strCardNoThis;
                    textBox8.Text = strCardNoThis;
                }
            }

            //显示读取到的身份证UID
            if (person.UID == null || person.UID.Equals(""))
            {
                textBox1.Text = "未读取到身份证UID";
            }
            else
            {
                textBox1.Text = person.UID;
            }
        }
    }
}

3.读取身份证逻辑代码 GetCardInfo.cs 如下
