serialize/deserialize problem [UnResolved]

[Techno]

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:

System.InvalidOperationException was unhandled
Message="An error message cannot be displayed because an optional resource assembly containing it cannot be found"
StackTrace:
at System.Xml.Serialization.XmlSerializer.Deserialize()
at System.Xml.Serialization.XmlSerializer.Deserialize()
at System.Xml.Serialization.XmlSerializer.Deserialize()
at SomeApp.IncomingData.DoHandleIncomingXml()
at SomeApp.IncomingData.DoAnalyzeData()
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

[Rattlerr]

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...

[Techno]

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!

[Rattlerr]

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

using (blahblah.xml)

[Techno]

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

[Rattlerr]

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;

// 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...

[Techno]

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

[Techno]

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:

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

[Rattlerr]

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

[Techno]

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????

[Rattlerr]

Example
Hope this Helps..

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

[Techno]

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

[Rattlerr]

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

[Techno]

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...

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

[Rattlerr]

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...

[Techno]

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
