How to serialize a non-serializable class in .Net

Ok jean im not for sure if this helpful, but this is code sample of what im doing, Im going to post various ways you can do it.

    private List TestObjectEventTableList = new List();

     public static class Extensions
    {

        public static void WriteAllToConsole(this IEnumerable junk)
        {
            int counter = 0;
            foreach (var item in junk)
            {
                Console.Write(counter++ + ". ");

                Console.WriteLine(item);
            }

       }

    }



        public class TestObjectEvent
        {
            public Int32 TPC_ID;
            public Int32 TestSequenceNumber;
            public Int32 TestObjectEventNumber;
            public string TestObjectName;
            public DateTime Start_Time;
            public DateTime Stop_Time;
            public string TOE_Status;
            public override string ToString()
            {
                return string.Format("{0}, {1}, {2}, {3}, {4}, {5}, {6}",
                                     TPC_ID,
                                     TestSequenceNumber,
                                     TestObjectEventNumber,
                                     TestObjectName,
                                     Start_Time,
                                     Stop_Time,
                                     TOE_Status);
            }

        }

       then I call the WriteAllToConsoleFunction I created at the top,

       TestObjectEventTableList.WriteAllToConsole();


       I cut out the code  where im filling the TestObjectEventTableList. but this just a ideal, like I said also lookup the objectdumper

Im doing something similiar to what you are doing, but im storing the list or should i say well the record into mdb file,
im using a Dictionary TestClass :
                 List example ; etc...........
        
also lookup something call objectdumper I havent using it in along time, where you actually dump your object in the ocean if you want or whatever you want to dump it to.
Let me see if I still have a code sample I did a  long time ago and I will post a sample

Dude.

Read your initial post for this thread; I did. You said "a list". You did not say the data is complicated.

Your problem description is very incomplete.

Dude.
My list contains objects of Employee, Item, Category etc.. which are having different properties.  So for storing into a text file as a record I need to do lot of code and rework whenever the properties get changed.
Also the Employee can have properties of type Project which is another class and Project can be connected to Manager that is another Employee.
