Can I serialize an object if I didn't write the class used to instantiate that object?
- by Richard77
Hello,
I've a simple class
[Serializable]
public class MyClass
{
public String FirstName { get; set: }
public String LastName { get; set: }
//Bellow is what I would like to do
//But, it's not working
//I get an exception
ContactDataContext db = new ContactDataContext();
public void Save()
{
Contact contact = new Contact();
contact.FirstName = FirstName;
contact.LastName = LastName;
db.Contacts.InsertOnSubmit(contact);
db.SubmitChanges();
}
}
I wanted to attach a Save method to the class so that I could call it on each object. When I introduced the above statement which contains ContactDataContext, I got the following error "In assembly ... PublicKeyToken=null' is not marked as serializable"
It's clear that the DataContext class is generated by the framework (). I checked and did not see where that class was marked serialize.
What can I do to overcome that? What's the rule when I'm not the author of a class? Just go ahead and mark the DataContext class as serializable, and pretend that everything will work?
Thanks for helping
