Hi,
This is something we are willing to resolve but it is not easy. Anyway, we'll found a solution ;-)

Hi,
I just ran into the same problem.
Is there an easier workaround than creating a new model yet ?

Except for this issue karvonite has been a dream to use,
Thanks!

Overview
Karvonite is an object persistence framework for the .NET platform. Karvonite's goal is to relieve the developer from all serialization related programming tasks in a non-invasive way. It can save you from writing a lot of boring and thus error-prone code for moving the in-memory objects to and from the data storage. The Karvonite API is very simple and provides a gradual learning curve with a very low entry point.

Despite the fact that .NET serialization and XML files are ideal for storing data easily and effectively, in several cases they are not a viable replacement for a data engine. In contrast, not all applications require the horsepower and the excessive functionality and optimization of an enterprise database or a SQL engine; databases are a skill unto themselves and the learning curve is not as fast as expected.

Hi,
Workaround, try this:

private Dictionary<int, string> testDict = new Dictionary<int, string>();

public Dictionary<int, string> TestDict
{
get { return testDict; }
set { testDict = value; }
}

Any news on that update? I do not see a new build on the downloads tab.

Does anybody have any ideas? It's been a couple days now and I'm kind of stuck. :)

NEW POST: serialization issue

jdsmith2816 — Fri, 09 Oct 2009 15:53:01 GMT

I set up a very simple test case this morning that does not work either.. In the example code below I simply left the deserializatin commented.. ran the code to create and add the testClass.. commented out that code the uncommented the deserialization.. and inside of the returned testClass the testDict was null.

public class TestClass
{
public TestClass()
{
}

public Dictionary<int, string> TestDict { get; set; }
}

if (!File.Exists(@"d:\test.dat")) {
_os.CreateObjectLibrary(ExistingFileAction.DoNotOverwrite);
}

_os.Open();

/*
var testClass = new TestClass();
testClass.TestDict = new Dictionary<int, string>();
testClass.TestDict0 = "omg";
_os.Add(testClass);
_os.SaveAndClose();
*/

var testClass = _os.OfType<TestClass>().First();

I switched over to a standard Dictionary and I'm still showing the _tiles dictionary as null upon deserialization. I did confirm that, at the time of calling _os.Add(level); and _os.Save(); that the _tiles dictionary most definately as populated.

Greetings again!

I'm trying to serialize my level structure. Currently my Level class contains a private SerializableDictionary<int, LevelSquare> _tiles; this is failing to serialize/deserialize.

SerializableDictionary is simply a dictionary that implements IXmlSerializable which allows the standard serialization/deserialization functions in .Net to work on it.

LevelSquare is a very simple class containing two shorts, one string, and one bool.

Upon de-serialization the _tiles member of my Level class is coming back with a null exception when I inspect it after breaking directly following the load process. What am I doing wrong?

Now that I'm using Karvonite I guess it no longer needs to be a SerializableDictionary so I'll try switching that back to a standard Dictionary but I don't think that's the problem?

Multidimensional arrays are not supported. All supported types are explained in the Karvonite Overview documentation document.
