c# – 如何通过套接字发送外部库的可序列化对象？

[Serializable]
    public class SendingObject : MarshalByRefObject
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }

        public SendingObject() { }

        public SendingObject(string firstname,string lastname)
        {
            FirstName = firstname;
            LastName = lastname;
        }

        public override string ToString()
        {
            return string.Format($"Firstname: {FirstName}. Lastname: {LastName}.");
        }
    }

这是我的客户的代码：

class Program
        {
            static void Main(string[] args)
            {   
                string path = @"path to MyLibrary.dll";
                Assembly library = Assembly.LoadFrom(path);

                Type typeObj = library.GetType("MyLibrary.SendingObject");
                var sob = Activator.CreateInstance(typeObj,new object[] {"Bob","Smith"});

                try
                {
                    SendAddUserMessageFromSocket(83,sob);
                }
                catch (Exception exc)
                {
                    Console.WriteLine(exc.Message);
                }

                Console.WriteLine("nTap to continue...");
                Console.ReadKey(true);
            }

            static void SendAddUserMessageFromSocket(int port,object obj)
            {    
                byte[] brr = ObjectToByteArray(obj);

                IPHostEntry ipHost = Dns.GetHostEntry("localhost");
                IPAddress ipAddress = ipHost.AddressList[0];
                IPEndPoint endPoint = new IPEndPoint(ipAddress,port);

                Socket sender = new Socket(ipAddress.AddressFamily,SocketType.Stream,ProtocolType.Tcp);

                sender.Connect(endPoint);

                NetworkStream networkStream = new NetworkStream(sender);

                if (networkStream.CanWrite)
                {
                    networkStream.Write(brr,brr.Length);
                }

                Console.WriteLine("The message was sent.");
            }

            // Convert an object to a byte array
            private static byte[] ObjectToByteArray(Object obj)
            {
                if (obj == null)
                    return null;

                BinaryFormatter bf = new BinaryFormatter();
                MemoryStream ms = new MemoryStream();
                bf.Serialize(ms,obj);

                return ms.ToArray();
            }

            // Convert a byte array to an Object
            private static Object ByteArrayToObject(byte[] arrBytes)
            {
                MemoryStream memStream = new MemoryStream();
                BinaryFormatter binForm = new BinaryFormatter();
                memStream.Write(arrBytes,arrBytes.Length);
                memStream.Seek(0,SeekOrigin.Begin);
                Object obj = (Object)binForm.Deserialize(memStream);

                return obj;
            }
        }

此接收的对象将在服务器端反序列化.这是我服务器的代码.

class Program
    {
        static void Main(string[] args)
        {
            IPHostEntry ipHost = Dns.GetHostEntry("localhost");
            IPAddress ipAddr = ipHost.AddressList[0];
            IPEndPoint endPoint = new IPEndPoint(ipAddr,83);
            Socket socketListener = new Socket(endPoint.AddressFamily,ProtocolType.Tcp);

            string path = @"path to MyLibrary.dll";
            Assembly library = Assembly.LoadFrom(path);
            Type typeObj = library.GetType("MyLibrary.SendingObject");

            try
            {
                socketListener.Bind(endPoint);
                socketListener.Listen(10);
                bool isWorkFinished = false;

                while (!isWorkFinished)
                {
                    Socket handler = socketListener.Accept();
                    byte[] bytes = new byte[2064];

                    // Get data from connected socket to buffer
                    int numberOfReceivedBytes = handler.Receive(bytes);

                    byte[] bytesObject = new byte[numberOfReceivedBytes];

                    for (int i = 0; i < numberOfReceivedBytes; i++)
                        bytesObject[i] = bytes[i];

                    object res = ByteArrayToObject(bytesObject);
                }
            }
            catch (Exception exc)
            {
                Console.WriteLine(exc.Message);
            }

            Console.WriteLine("nTap to continue...");
            Console.ReadKey(true);
        }

        // Convert an object to a byte array
        private static byte[] ObjectToByteArray(Object obj)
        {
            if (obj == null)
                return null;

            BinaryFormatter bf = new BinaryFormatter();
            MemoryStream ms = new MemoryStream();
            bf.Serialize(ms,obj);

            return ms.ToArray();
        }

        // Convert a byte array to an Object
        private static Object ByteArrayToObject(byte[] arrBytes)
        {
            MemoryStream memStream = new MemoryStream();
            BinaryFormatter binForm = new BinaryFormatter();
            memStream.Write(arrBytes,arrBytes.Length);
            memStream.Seek(0,SeekOrigin.Begin);
            Object obj = (Object)binForm.Deserialize(memStream);

            return obj;
        }
    }

我的SendingObject可以序列化,但我尝试反序列化时出错.

The assembly can’t be found:”MyLibrary,Version=1.0.0.0,
Culture=neutral,PublicKeyToken=null”.
