神思通用100型读身份证

之前为了能做硬件操作学习了C++，一直停留在试验阶段。由于之前项目都是HIS做好读卡对接了，就直接C#调HIS的dll了，一直没实际用C++对接过读卡器。这次终于有了个读卡机会，还有厂商配合，哈哈。

采用C++包装读卡操作为一个读卡方法如下：

//检验读身份证包装
#include <iostream>
#include "windows.h"
using namespace std;//读身份证对外函数
extern "C" __declspec(dllexport) const char* LISReadIDCard();//方法定义

}

该项目先编译成exe控制台测试可不可以读身份证。如果控制台好使了再编译成dll供C#调用。这里碰到一个坑是我以Debug模式编译的exe到没开发环境的电脑就算安装VC2015运行时还报错。后面宏伟兄发现我是Debug编译导致的。由于之前一直用C#写，C#的Debug编译没影响，所以不知道还要这出（这里要记得以Release模式编译额）。

然后碰到的问题就是开始C++包装的方法返回string。然后在C#用String接返回值程序会崩溃。

这里给C++方法返回改为const char*（即字符串指针），然后C#用IntPtr接指针，然后从指针取字符串数据。

C#包装如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;
using System.Windows.Forms;
using ReadCardService;namespace HLJHYZYYReadCard
{public class ReadCard : IReadCard{/// <summary>/// 读身份证/// </summary>/// <returns></returns>[DllImport("LISReadCard.dll")]public static extern IntPtr LISReadIDCard();/// <summary>/// 读卡1-就诊卡，2-医保卡，3-身份证/// </summary>/// <param name="type">卡类型</param>/// <returns></returns>public string Read(string type){IntPtr ret = LISReadIDCard();string str = Marshal.PtrToStringAnsi(ret);if (str.Substring(0, 3) == "-1^"){return "";}str = str.Replace("^","&");return str;}}
}

最终把接口实现配置到公共读卡程序里，让程序通过反射加载调用，程序再模拟条码枪，就把身份证读卡模拟为扫码操作了，界面只要实现回车事件处理即可。

最终刷一次就等于一次扫码

总算是把C++和C#结合用起来了，积累、成长、坚持
