我用IPEndpoint创建一个TcpClient，并用打开的连接打开一个NetworkStream。

stream = client.GetStream();

Stream定义为NetworkStream，client定义为TCPClient。我想使用流每秒发送序列化对象。为此，我有一个定时器，它通过BinaryFormatter发送每一秒钟的信息。

formatter.Serialize(stream, object);

对象在本例中是序列化类。在另一边，我使用一个TcPListener并使用

stream = listener.AcceptTcpClient().GetStream();

在那之前，一切都按计划进行。第一个对象有我想要的信息，我甚至能够访问这些信息。只要我想从同一个流中获取第二个对象，我就会收到一个NullReferenceException。

streamObject = deserialiser.Deserialize(stream);

我不反序列化到特定的类型，所以我可以筛选对象并启动不同的方法。*注意，我使用两个不同的类发送和接收，两个类运行在不同的程序中。

我的问题是:有没有可能在相同的流中发送多个对象，中间有一个时间间隔，然后在另一端反序列化它，而不是每次都打开和关闭一个流？

*一些附加信息:

计时器作为线程在Windowsservice中运行。第一个对象将按照上面提到的方式发送，但是第二个对象不会。

这里询问的是我收到的堆栈跟踪。

下面是我的Page_Load方法。

protected void Page_Load（object sender，EventArgs e）{recient=new serverrecient（）；recive.recivestreamobject（）；firstdate.text=recive.ui.servername；}

一旦我定义recient，连接就会打开。这里是整个类ServerRecient的代码。

  public class ServerRecive
 {
public ObjectTypeUI ui {get; set;}
public ObjectTypeSI si { get; set; }
public ObjectTypeDI di { get; set; }

TcpListener listener;
NetworkStream stream;

BinaryFormatter deserialiser;

public ServerRecive ()
{
 deserialiser = new BinaryFormatter();
 Initialize();
}

private void Initialize ()
{
listener = new TcpListener (IPAddress.Any, *port*);
listener.Start();
stream = listener.AcceptTcpClient().GetStream();
}


public void ReciveStreamObject()
{
object Object = new object();
try
 {
  Object = deserialiser.Deserialize(stream);
 }
 catch (Exception e) {}

 if (Object.GetType() == typeof(ObjectTypeSI))
 {
  si = (ObjectTypeSI)Object;
 }
 else if (Object.GetType() == typeof(ObjectTypeUI))
 {
  ui = (ObjectTypeUI)Object;
 }
 else if(Object.GetType() == typeof(ObjectTypeDI))
 {
  di = (ObjectTypeDI)Object;
 }
}
}

我没有任何具体的大小对象，因为他们包含不同的信息。

@Nelus我做了一些变通方法来获得异常。现在我收到了这个例外
