How to serialize only objects id

I have two classes

[Serializable]
public class SimpleClass
{
    public ComplexClass Parent { get; set; }
}

public class ComplexClass
{
    public Guid Id { get; set; }
    // Lots of stuff
}

... 
// and somewhere    
public static List<ComplexClass> ClassesList;

How to serialize SimpleClass so that only Guid is saved from complex class? How to deserialize it afterwards? Suppose I already have collection of ComplexClasses and only need to pick one by id.

I'm using XmlSerializer for serialization

It would be possible to make a custom serialization of course using ISerializable, but if you want to keep it simple then something like this might work:

public class SimpleClass
{
    [XmlIgnore]
    public ComplexClass Parent { get; set; }

    public Guid ComplexClassId { 
        get { return Parent.Id; } 
        set { Parent = new ComplexClass(value); } 
    }
}

Or just mark the unwanted fields in ComplexClass using XmlIgnore.

I have changed my answer to use XmlIgnore instead of NonSerialized based on comment from L.B. Left the answer here because I think it still adds some info to Andypopa.

Include the Namespace System.Xml.Serialization and adding the attribute [XmlIgnore] over the field or property that you want to be excluded in Serialization.
