C# .NET智能卡-序列化/反序列化远程对象。输入流的格式无效
我使用的是.NET智能卡，它与.NET远程处理的概念相同 因此，我的智能卡（作为服务器）具有以下服务：C# .NET智能卡-序列化/反序列化远程对象。输入流的格式无效,c#,.net,serialization,smartcard,gemalto,C#,.net,Serialization,Smartcard,Gemalto,我使用的是.NET智能卡，它与.NET远程处理的概念相同 因此，我的智能卡（作为服务器）具有以下服务： public class MyService : MarshalByRefObject { string a = "abC"; public byte[] MySampleMethod() { MyService obj = new MyService(); return help.ObjectToByteArray( obj);

Gemalto.NET智能卡仅支持通过引用进行封送，因此可以在客户端访问服务器中的任何基元和结构类型，而无需序列化，因为您已经通过远程调用对对象进行了引用： 因此，首先注册您的服务：
public class MyServer
{
/// <summary>
/// specify the exposed remote object URI.
/// </summary>
private const string REMOTE_OBJECT_URI = "MyService.uri";
/// <summary>
/// Register the server onto the card.
/// </summary>
/// <returns></returns>
public static int Main()
{
// Register the channel the server will be listening to.
ChannelServices.RegisterChannel(new APDUServerChannel());
// Register this application as a server
RemotingConfiguration.RegisterWellKnownServiceType(typeof(MyService), REMOTE_OBJECT_URI, WellKnownObjectMode.Singleton);
return 0;
}
}
public class MyClient
{
private const string URL = "apdu://selfdiscover/MyService.uri";
public static void Main()
{
// create and register communication channel
APDUClientChannel channel = new APDUClientChannel();
ChannelServices.RegisterChannel(channel);
// get the referenc to remote object
MyService service = (MyService)Activator.GetObject(typeof(MyService), URL);
Console.WriteLine(service.MySampleMethod());
MyService.Person person = service.getPerson();
Console.WriteLine(person.getName());
Console.WriteLine(person.getId());
Console.ReadLine();
// unregister the communication channel
ChannelServices.UnregisterChannel(channel);
}
}
上面的十六进制字符串中缺少了“T”：P，说真的，我不是.NET卡专家，但是客户机如何知道序列化了哪种类型的对象？如果可能的话，请显示完整的二进制格式。你说的“客户端如何知道”是什么意思，实际上我在客户端添加了server.exe的引用，如果这是你要求的，你有更多的数据吗？上面的“起始内容”中缺少第一个字节，它似乎是某种类型的指示符，它以
