How to implement Xml Serialization with inherited classes in C#

Question

I have two classes : base class name Component and inheritd class named DBComponent

[Serializable]
public class Component
{
    private string name = strin         


        

Answer 1

Two options for different scenrios: tell the base-class

[XmlInclude(typeof(DBComponent))]
public class Component
{
    private string name = string.Empty;
    private string description = string.Empty;  
}

Or: tell the collection:

[XmlArray]
[XmlArrayItem("Component", typeof(Component))]
[XmlArrayItem("DBComponent", typeof(DBComponent))]
public List Components {...}

Actually, you can also use [XmlElement(...)] in place of [XmlArrayItem] if you don't want the outer node (Components). Also: you don't need [Serializable].
