c#对智能卡的操作? c#对ic卡的操作有没有哪位大大做过?就是实现读卡器的读卡和写卡的功能我知道是用接口函数假设我现在买的读卡器已经给了个 xxx.dll的链接库具体下面我该怎么操作呢?抱歉我是个小菜,什么都不会希望能给个思路,最好是代码今天晚上就要用,急等 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 以前看的一本书上有操作ic卡的例子我给你贴出来,但是每个ic卡的链接库应该都是不同的,你看看思路自己编写相关部分吧。下面这个是写IC卡的例子:using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;using System.Runtime.InteropServices;namespace ICw{ public partial class Form1 : Form { public Form1() { InitializeComponent();
