What you need is a data contract serializer to push data across the
pipe (the example below is only for outgoing). If it see's an
uninitialized proxy, it will skip serialization on it.
using System;
using System.CodeDom;
using System.Reflection;
using System.Runtime.Serialization;
using System.Collections.ObjectModel;
using log4net;
using NHibernate.Proxy;
namespace MyNamespace.ServiceModel {
public class NhDataContractSurrogate : IDataContractSurrogate {
private static readonly ILog log = LogManager.GetLogger(typeof
(NhDataContractSurrogate));
#region IDataContractSurrogate Members
public object GetObjectToSerialize(object obj, Type
targetType) {
log.Debug("Checking object");
var proxy = obj as INHibernateProxy;
if (proxy != null) {
log.Debug("Hibernate proxy found");
var li = proxy.HibernateLazyInitializer;
if (li.IsUninitialized) {
log.Debug("Hibernate proxy is not initialized and
will not be serialized");
obj = null;
}
else {
obj = li.GetImplementation();
log.DebugFormat(
"Hibernate proxy was initialized and has been
casted to its implementation of type '{0}'",
obj.GetType().FullName
);
}
}
return obj;
}
public object GetCustomDataToExport(Type clrType, Type
dataContractType) {
return null;
}
public object GetCustomDataToExport(MemberInfo memberInfo,
Type dataContractType) {
return null;
}
public Type GetDataContractType(Type type) {
return type;
}
public object GetDeserializedObject(object obj, Type
targetType) {
return obj;
}
public void GetKnownCustomDataTypes(Collection<Type>
customDataTypes) {
}
public Type GetReferencedTypeOnImport(string typeName, string
typeNamespace, object customData) {
return null;
}
public CodeTypeDeclaration ProcessImportedType
(CodeTypeDeclaration typeDeclaration, CodeCompileUnit compileUnit) {
return typeDeclaration;
}
#endregion
}
}
