Hi,
I want to send XML data from a server to some clients over a network
connection using the TCP/IP protocol. If I send the XMLs as byte
arrays I need to insert header information in the data to distinguish
the XMLs from each other in the stream of data. Is there any way to
avoid this (for instance by sending SOAP telegrams))?
I have tried using the XMLSerializer.S erialize(stream ) to serialize
the XML telegrams and send them over the socket connection but when I
want to use the XMLSerializer.D eserialize(stre am) to read the sent
telegrams it either newer finishes or returns a xml parse error.
//Send the XML
ShoppingList myList = new ShoppingList();
myList.AddItem( new ShoppingItem("e ggs", 1.49));
myList.AddItem( new ShoppingItem("g round beef", 3.69));
myList.AddItem( new ShoppingItem("b read", 0.89));
XmlSerializer s = new XmlSerializer(t ypeof(ShoppingL ist));
stream = new NetworkStream(m _socWorker);
s.Serialize(str eam, myList);
//Receive the XML
// Deserialization
ShoppingList newList;
XmlSerializer s = new XmlSerializer(t ypeof(ShoppingL ist));
newList = (ShoppingList)s .Deserialize(st ream);
What am I doing wrong? Will the Deserialize() method be able to
separate the XML telegrams in the stream automatically?
Best regards,
Kim

Unfortunately, no. What you should do is before each serialized type
you want to send, send the length of the XML document you are going to send.
Then, on the other side, take note of the length, and only read that much
into a byte array, or something of the sort, and then pass that to the
XmlSerializer. Finally, repeat for all other instances.

Thank you for your answer.
I am a bit disappointed that the XMLSerializer.D eserialize(Stre am)
method is actually more or less useless when trying to read from a
Networkstream. It would be nice to have a some sort of class that you
could just wrap around the whole thing and then you could send the
objects from one computer and receive the objects on another computer
as an object array without having to worry about separating the data.
Best regards,
Kim Therkelsen

Hi,
If you can manage both sides of the application, I would suggest using
Web Services Enhancements SOAP messaging over tcp.
If not, Nich just pointed the solution for you.

I am trying to find a solution that will allow me to use XmlSerializer to serialize/deserialize a collection of objects where a given object is shared between two or more other objects, and not create duplicate XML representations of the shared object, but instead use IDREFs to refer to the shared object.
The XML I'm trying to produce is as follows (where "href" is an IDREF):

Hi
I've been reading using the XmlSerializer with custom collections.
I've discovered that when serializing a custom collection (a class that
implements ICollection, IList etc.) the XmlSerializer will only serialize
the collection items - with the default root as ArrayofMyItems etc.
My custom collection class has some additional public properties that I
would like to include in the serialization above the items element array (in

I, too, am getting nasty FileNotFound exceptions. I've read, and
