Serialize Object

Question

I am new to serialization and I cannot for the life of me figure out how to fix this exception I am getting...

I have an object that has the following structure

[XmlRoot("MaxCut2")] public class MaxCut2File : IFile { public MaxCut2File() { MyJob = new Job(); Job.Reference = "MyRef"; } [XmlElement("JobDetails", typeof(Job))] public IJob MyJob { get; set; } }

An inteferface...

 public interface IJob { string Reference { get; set; } }

And an class

[Serializable()] public class Job : IJob { [XmlElement("Reference")] public string Reference { get; set; } }

When I try to serialize an instance of the MaxCut2File object I get an error

{"Cannot serialize member 'MaxCut2File.MaxCut2File.MyJob' of type 'MaxCut2BL.Interfaces.IJob', see inner exception for more details."} "There was an error reflecting type 'MaxCut2File.MaxCut2File'."

However if I change my property MyJob from the IJob type to the Job type it works fine...

Any ideas?

You cannot serialize an interface. How would the serializer know which type will be used? You simply said there's an interface.

Try adding:

public interface IJob : ISerializable
