比.Net Micro Framework还小的.net Framework

这是飞天的最新一款智能卡产品，前短时间抽时间研究了一下，整体感觉还不错，实现了clr中有关文件操作（有些函数好像有些问题）、加密算法等指令。

由于我们这边的项目组开发的就是MF3.0的文件系统，所以对它们这个这么小的东东有CPU、有操作系统，支持clr，并且支持文件系统很感兴趣。

它的文件系统是FAT16（MF实现的是FAT32，这就要求存储空间至少有32.52M），通过PC上的一个程序可以实现上下传文件。此外该系统最大的特点就是可以执行.net程序。

下面是简单的程序，一个是运行在智能卡上（server），一个运行在普通PC上。

//服务端程序，需要用上面的工具（load file）把编译好的程序上传到智能卡上，然后在设置运行即可。

using System.Runtime.Remoting;

using System.Runtime.Remoting.Channels;

using SmartCard.Runtime.Remoting.Channels.APDU;

public class MyServer

///<returns></returns>

public static int Main()

{

//Register communication channel for server to start listening

ChannelServices.RegisterChannel(new APDUServerChannel());

//Register application as a service

RemotingConfiguration.RegisterWellKnownServiceType(typeof(MyService), REMOTE_OBJECT_URI, WellKnownObjectMode.Singleton);

return 0;

}

}

}

//客户端程序，在PC机上运行，可以远程执行服务端上的函数有点DCOM的感觉。
