使用混合类型的对象从XML文件生成C＃类

Question

I have classes like below

public abstract class MainDTO
{
   public string Id;
   public string CreatedBy;
}

public class SubDTO : MainDTO
{
   public string SubKey;
}

public class LockDTO : SubDTO
{
   public string LockKey;
}

I need to create a function that returns List<MainDTO> . My xml file is like below.

<MainDTOList>  
  <SubDTO>
    <Id>ABC</Id>
    <CreatedBy>XXX</CreatedBy>
    <SubKey>123045</SubKey>
  </SubDTO>
  <LockDTO>
    <Id>GERTE</Id>
    <CreatedBy>VGINA</CreatedBy>
    <SubKey>123045</SubKey>
    <LockKey>L123045</SubKey>
  </LockDTO>
</MainDTOList>

I got the code to read XML file and return collection of objects when all objects are off same type by using XmlSerializer. But in my case they are different. Can you please let me know how to do it.

The simple way I can think of that you can achieve the above is to look at your XML structure, haven't use this in a bit, so forgive my small assumption mistakes

The idea is to create a class that looks like your XML, if the values only apear once, the use a class that looks like this(as a sample)

[XmlRoot("MainDTOList")]
public class SomeClass
{
    [XmlElement("SubDTO")]
    public SubDTO SubDTO{get;set;}

    [XmlElement("SubDTO")]
    public LockDTO LockDTO{get;set;}

    ....

}

Then doing a simple XmlSerializer. Deserialize to deserialize your specific XML
