Hi,

My problem is the following. I am retrieving data from the database using Linq to sql and then binding that data to controls on my windows forms. The next part of my application I want to get the changes made to the data and serialize then to either XML or binary. Then when i load the application the second time i want to deserialize that data and commit the changes that where made in the previous "session".

I am trying to serialize my Linq to sql entities but it's no use. Maybe you guys can point me to an article or tutorial or provide some guidance as i tried many things and looking trough the internet for possible solutions and cant find anything.

Your help is greatly appreciated guys.

Thx a lot.

If you used Entity Framework, then all entity become serializable. So try serialization and De-serialization process:
C#
SomeModel model = ...
var serializer = new XmlSerializer(typeof(SomeModel));
using (var writer = XmlWriter.Create("foo.xml"))
{
    serializer.Serialize(writer, model);
}
and to deserialize back a XML to an existing model:

var serializer = new XmlSerializer(typeof(SomeModel));
using (var reader = XmlReader.Create("foo.xml"))
{
    var model = (SomeModel)serializer.Deserialize(reader);
}

Yes will this keep track of the inserts and updates that have been done? Because in my i case i want to temporary save the data and then commit the changes at a later time.

It's depend the how you are managing your DBContext object, fist look into this URL about the lifecycle of DBContext then you will able to implement your scenario:
