How to use Dataobject.net with WCF

Alexey Kulakov wrote

DataObject.Net has serialization of Entities...

I can find no reference to serialization in the DO documentation. How can an Entity object be serialized?

Accepted Answer

I've been experimenting with the "Simple example" code provided by Support, and from what I can tell, it doesn't work at all if the stream is not deserialized within the same process that serialized it to begin with. The stream appears to contain no actual data (perhaps it has a reference to a cached object in memory?). In other words, as far as I can tell, the object has not actually been serialized. Sending the serialized object to another process (sort of the whole point of serialization) won't work this way.

Hi TimB

Simple example for you


// formatter for serialization
BinaryFormatter formatter = new BinaryFormatter();
.....
//serialization
using (var session = Domain.OpenSession()) {
  using (var transactionScope = session.OpenTransaction()) {
    Company company = new Company {Name = companyName};
    //This is DO serialization context
    using (new SerializationContext(entity => SerializationKind.ByReference).Activate()) {
      // serialization to stream
      formatter.Serialize(stream, company);
    }
    transactionScope.Complete();
  }

//deserialization
using (var session = Domain.OpenSession()) {
  using (var transactionScope = session.OpenTransaction()) {
    stream.Position = 0;
    Company deserializedCompany = (Company) formatter.Deserialize(stream);
  }
}
