Member not found error when serializing a Dictionary<> derived object

Question

I am trying to serialize a class that inherits from Dictionary<string, anObject> and am getting a SerializationException…

 

"Member 'Version' was not found."

 

My object does not contain a “Version” member. I assume that it is a private member of the Dictionary<>.  I would be grateful for any help in correctly implementing an object derived from Dictionary<>.

 

TIA

Here is how I am implementing the object:

 

    [Serializable()]

    public sealed class InputData : Dictionary<string, MmpControlDataBase>, ISerializable

    {

        #region Member Variables

        private int numberOfFlights;

        private int numberOfRuns;

        private double h2oFactor;

        private double co2Factor;

        private double soxFactor;

        private string database;

        private string date;

 

        // create the single instance

        private static InputData inputData = new InputData();

        #endregion Member Variables

 

        private InputData()

        {

        }

 

        private InputData(

            System.Runtime.Serialization.SerializationInfo info,

            System.Runtime.Serialization.StreamingContext context)

            : base(info, context)

        {

            numberOfFlights = info.GetInt32("numberOfFlights");

            numberOfRuns = info.GetInt32("numberOfRuns");

            h2oFactor = info.GetDouble("h2oFactor");

            co2Factor = info.GetDouble("co2Factor");

            soxFactor = info.GetDouble("soxFactor");

            database = info.GetString("database");

            date = info.GetString("date");

        }

 

        void ISerializable.GetObjectData(

SerializationInfo info,

StreamingContext context)

        {

            if (info == null)

                throw new ArgumentNullException("info");

 

            info.AddValue("numberOfFlights", numberOfFlights);

            info.AddValue("numberOfRuns", numberOfRuns);

            info.AddValue("h2oFactor", h2oFactor);

            info.AddValue("co2Factor", co2Factor);

            info.AddValue("soxFactor", soxFactor);

            info.AddValue("database", database);

            info.AddValue("date", date);

        }

 

Answer 1

As often happens, after the post I found the error. I did not make a call to base.GetObjectData() in my GetObjectData() method.
