C# - Check Compile Time That Type Is Marked With The Serializable Attribute?
Jan 26, 2011Specifically we're making our application compatible with the Out Of Process Session State server where all types saved in session must be serializable. Is there a way to see at compile time that any type put into HttpSessionState is marked with the Serializable attribute. Something along the lines of this 'non-valid' code
public static void Put<T>( string key, T value ) where T : IsMarkedWitheSerializableAttribute
{
HttpContext.Current.Session[key] = value;
}

View 1 RepliesDetermine Which Classes Are Serializable?
Aug 16, 2010I am changing my ASP.NET app to use a web farm. To do this, I need to change the session state from in-proc to a State Server. To do this, it is my understanding that the classes that are used must be marked as serializable. How can you tell if that is possible with a class? Will you get an error at compile time if it is not possible?

View 1 RepliesReturn Serializable Object From FileStream?
Dec 30, 2010I'm a little green when it comes to streaming and serialization...but what i wanna do is make the Upload method on the server return a serializable object to the client (it is void right now). I have a public class ServiceResult that i decorate with [Serializable], and a public class FileTransferService that implements IFileTransferService
[ServiceContract()]
public interface IFileTransferService
{
[OperationContract(IsOneWay = false)]
string Upload(FileTransferRequest request);
}
The implementation does its thing, and then at the end i create and serialize the object and try to return the string
return ServiceResultSerializer.SerializeAnObject(result);
On the client side i call this service using this class
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")]
[System.ServiceModel.ServiceContractAttribute(ConfigurationName = "IFileTransferService")]
public interface IFileTransferService
{
// CODEGEN: Generating message contract since the wrapper name (FileTransferRequest) of message FileTransferRequest does not match the default value (Upload)
[System.ServiceModel.OperationContractAttribute(IsOneWay = false, Action = "http://tempuri.org/IFileTransferService/Upload")]
string Upload(FileTransferRequest request);
}
I'm basically taking this project found on this blog: [URL] And trying to make it return a value that the client caller can use I get an error right now that says: The operation 'Upload' could not be loaded because it has a parameter or return type of type System.ServiceModel.Channels.Message or a type that has MessageContractAttribute and other parameters of different types. When using System.ServiceModel.Channels.Message or types with MessageContractAttribute, the method must not use any other types of parameters. Which i have no idea what it means :P I think cuz im trying to change the Service paramaters.
C# - Object Serializable For AJAX - WCF And ViewState
Jun 30, 2010consider the following class and struct
public class Entity {
public IdType Id {get;set;}
public string Data {get;set;}
}
[TypeConverter(IdTypeConverter))]
public struct IdType {
... any data ...
}
The IdTypeConverter can convert the IdType struct from and to string. Now, what I want is this class to be serializable for AJAX, WCF and ViewState. The senario could be a WCF web service which provides as array of Entity[] to a DataSource. And a custom control which binds to the datasource, saves this class to it's ViewState and sends the data to client side code. This could be achieved easily by simply adding a [Serializable] attribute to all serialized types. But I don't want the IdType to be serialized, but to be converted to a string. Thus the JSON representation should be
{ 'Id'=>'StringRepresentationOfId', 'Data'=>'foo' }
This would analogously be the optimal serialization for WCF and ViewState. Another solution would be to write another class
public class JsonEntity {
public JsonEntity(Entity from) {
Id = from.Id;
Data = from.Data;
}
public string Id {get;set;}
public string Data {get;set;}
}
and use this for JsonSerialization. But I don't like this, because this would imply that the control which is sending the data to the client knows about the Entity type. The actual question is: Is it possible to customize JsonSerialization with attributes without breaking WCF and ViewState serialization? DIT: An answer like "That' impossible" would satify me, since I'd stop trying.

View 1 RepliesC# - To Be XML Serializable, Types Which Inherit From ICollection Must Have An Implementation Of Add?
Nov 10, 2010I have CSLA (1.x framework) objects from an existing project that I'm trying to use in a new .Net 4.0 project. The objects are being used in production and I really can't convert them to 2.x or EF without having 2 sets of objects.
In my c# webservice (when I try to run it) I am getting the following error:
To be XML serializable, types which inherit from ICollection must have an implementation of Add(objectname.object) at all levels of their inheritance hierarchy. objectname.objectList does not
implement Add(objectname.object).
Like I said these objects are CSLA objects written in vb.net. I don't know where to look on this one. Is it an issue of .Net 4.0 trying to talk to CSLA 1.x or is it a web service issue (as these objects never used web services originally)?
Does anyone have an idea about where I should look to figure out this issue? Should I suggest converting to CSLA 2.x?
