serialize/deserialize problem [UnResolved]

Hi!

ok, new to this. awesome stuff!

I am basically serializing objects in xml from a Server app to a client app. the client app takes this xml serialized object and deserializes it.

yes, both ends have the EXACT SAME class I am working with.

when the client tries to deserialize the object, I get an invalidoperationexception (nullreference) - no idea why.

this is the stack trace:

Quote:

---

System.InvalidOperationException was unhandled

at SomeApp.Communication.DoListenToIncomingPort()

I have only chosen to serialize some properties but not all, however this should be ok no?


This problem has been resolved, this is the new problem:

how do you read a string into a stream in order to pass it to the deserializer? Opening and writing to a file is not an option unfortunatly :)

Since your Serializing only a few..Try Serializing all of them...

Also in your using System do you have

using System.Web; or using System.Web.UI; ?
Might want to include "using System.Net;" also
Check your "using"

Also you might want too add ::
using System.Diagnotics;

in their if you dont already have it...

all the name spaces are there

tried to serialize all objects (Except for arraylist otherwise exception will be thrown when serializing it) and i still get the exception!

Ok what about your References? is System.Web in their?? I have noticed even if you have the using and dont include what your using in the References it will cause problems..

From what your saying it sounds like your missing a Reference...Add the
System.Web into ther References folder itself..

Also might want to make a Folder for the xml file if you havent already and include into the project...example

Code:

---

using (blahblah.xml)

---

im not using ASP.NET, just a standard C# winform application
ive also tried the suggestion but did not work

ok what type of Serialization are you using??

BinaryFormatter
SoapFormatter
XmlSerialization???

here are some using examples

using System.Runtime.Serialization.Formatters.Binary;

using System.Xml.Serialization;

Code:

---

// Example

public interface IFormatter
{
SerializationBinder{get; set;}
StreamingContext Context {get; set;}
ISurrogateSelector SurrogateSelector {get; set;}
object Deserialize(System.IO.stream serializationStream);
void Serialization(System.IO.Stream serializationStream, object graph);
}

---

The System.Runtime.Serialization.IFormatter defines the core Serialize() and Deserialize() methods,which do the grunt work...

hmmm think i solved the problem but that was testing stuff... moving away

tell me, how would YOU Deserialize xml? Give me your code to deserialize an xml object.

im using XmlSerialization

nevermind solved it

it was the way i was reading etc.. was reading the saved xml serialized file to a memoryReader and then doing other stuff... bleh.

this is the way to do it:

Code:

---

StreamReader sr = new StreamReader("blah.xml");
YourClass temp = new YourClass();
XmlSerializer serializer = new XmlSerializer(YourClass.GetType());
temp = (YourClass)serializer.Deserialize(sr);
sr.Close();

---

[CODE]
public interface IFormatter
{
object Deserialize(System.IO.Stream serializationStream);
void Serialize(System.IO.Stream serializationStream, object //put your object here);
}

actually for a minute lets reopen this thread. Stupid me, forgot what I was doing in the first place!!!!!!

since I am serializing xml over the networkstream, client recieves it in a string.

so how can I deserialize the string????

Example
Hope this Helps.. :)

Code:

---

[Serializable]
class MoreData
{
public string dataItemOne, dataItemTwo;
[OnDeserializing]
internal void OnDeserializing(StreamingContext context)
{
dataItemOne = dataItemOne.ToLower();
dataItemTwo = dataItemTwo.ToLower();
}
}
// Either [OnDeserializing] or [OnDeserialized]

---

whats this example for? :)

I need one where I can deserialize a string given to me since the serializer will be writing to a networkstream, so i need to deserialize the string given

Post up the Code you need Deserialized so i can see what i'm working with...lol

The Server uses the xml serialize to WRITE TO NETWORKSTREAM, not a file.
The Client recieves the content in string.
The Client then calls a method to deserialize the xml - the string that has been sent:

ok...

Code:

---

private void DoDeserializeXml(string theDataSentFromServer)
{
  //thats it! the entire code lol.
}

---

Well m8 i tried my best the only thing i can think of to cause the exception is its not reading the NetworkStream....Because the Exception mentions a Resource Assembly....That tells me its not seeing the Source Assembly...

Thanks mate but that's not what the problem is ;)
I have SOLVED the exception, but need to know HOW to convert string into a format I can give the deseralizer (i.e a Stream)

thanks tho! Much appreciated
