Serialization in SandBoxSolutions

Question

Hi,

I am building a SnadBox solution webPart that will store some data in SPWeb properties using spweb.AddProperty method.

I have build a custom configuration class and marked as serializable:

 

[Serializable]

public class MyConfig

{

public long size {get;set;}

public string text {get;set;}

}

 

I get the SPWeb from the current context but when calling web.AddProperty("Key",new MyConfig()) I get the following error:

System.Runtime.Serialization.SerializationException was unhandled  Message=Unable to find assembly ....

The method works just fine if I add the primitives dirrectly as string and long but not when I am trying to serialize my class.

It does seems like the serialization mechanism can't find the assembly so I wonder how the WF will find the assembly when is going to serialize/dehidrade.

Please advise.

My current solution would be to write methods that will manually serialize/deserialize the config class into a string but will require more code.

 

Answer 1

Is the MyConfig class defined in another dll ?

Answer 2

the Myconfig class is in the same dll with the webpart and is the only dll in the solution.
