C#如何读取24C64的数据？
现有一读卡机，可以读取24C64的内容，代码如下
using System;
using System.Runtime.InteropServices;
namespace WindowsApplication1
{
[StructLayout(LayoutKind.Sequential)]
public unsafe class IC
{
//对设备进行初始化
[DllImport("Mwic_32.dll", EntryPoint = "auto_init", SetLastError = true, CharSet = CharSet.Ansi, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
public static extern int auto_init(int port, int baud);
//获取设备当前状态
[DllImport("Mwic_32.dll", EntryPoint = "get_status", SetLastError = true, CharSet = CharSet.Ansi, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
public static extern Int16 get_status(int icdev, Int16* state);
//关闭设备通讯接口
[DllImport("Mwic_32.dll", EntryPoint = "ic_exit", SetLastError = true, CharSet = CharSet.Ansi, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
public static extern int ic_exit(int icdev);
//使设备发出蜂鸣声
[DllImport("Mwic_32.dll", EntryPoint = "dv_beep", SetLastError = true, CharSet = CharSet.Ansi, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
public static extern int dv_beep(int icdev, int time);
//向IC卡中写数据
[DllImport("Mwic_32.dll", EntryPoint = "swr_24c64", SetLastError = true, CharSet = CharSet.Ansi, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
public static extern int swr_24c64(int icdev, int offset, int len, char* w_string);
//向IC卡中读数据
[DllImport("Mwic_32.dll", EntryPoint = "srd_24c64", SetLastError = true, CharSet = CharSet.Ansi, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
public static extern int srd_24c64(int icdev, int offset, int len, char* r_string);
// public static extern int srd_24C64_Hex(int icdev,int offset,int le,ref
//检查卡是否正确
[DllImport("Mwic_32.dll", EntryPoint = "chk_24c64", SetLastError = true, CharSet = CharSet.Ansi, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
public static extern int chk_24c64(int icdev);
[DllImport("Mwic_32.dll", EntryPoint = "asc_asc", SetLastError = true, CharSet = CharSet.Ansi, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
public static extern int asc_asc(char* s_string, char* d_string, int len);
[DllImport("Mwic_32.dll", EntryPoint = "hex_asc", SetLastError = true, CharSet = CharSet.Ansi, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
public static extern int hex_asc(char* s_string, char* d_string, int len);
}
}
IC类调用Mwic_32.dll类，
Mwic_32.dll的方法如下：
