Hi
Here is some
dummy xml and
dummy xml schema I made.

Serialization Class
using System;
using System.Collections.Generic;
using System.Xml;
using System.Xml.Serialization;
[XmlRoot("vehicles")]
public class MyClass
{
public MyClass()
{
Cars = new List<Information>();
Trucks = new List<Information>();
SUVs = new List<Information>();
}
[XmlElement(ElementName = "owner")]
public string Owner { get; set; }
[XmlElement("Car")]
public List<Information> Cars { get; set; }
[XmlElement("Truck")]
public List<Information> Trucks { get; set; }
[XmlElement("SUV")]
public List<Information> SUVs { get; set; }
}
public class CarInfo
{
public CarInfo()
{
Info = new List<Information>();
}
[XmlElement("Information")]
public List<Information> Info { get; set; }
}
public class Information
{
[XmlElement(ElementName = "CarName")]
public string CarName { get; set; }
[XmlElement("CarPassword")]
public string CarPassword { get; set; }
[XmlElement("CarEmail")]
public string CarEmail { get; set; }
}
Now I think this should all validate. If not assume it is write as my real file does work and this is what this
dummy one is based off. Now my problem is this. I want to enforce as much as I can from my schema. Such as the "owner" tag must be the first element and should show up one time and only one time ( minOccurs="1" maxOccurs="1").
Right now I can remove the owner element from my
dummy xml file and deseriliaze it and it will go on it's happy way and convert it to object and will just put that property as null. I don't want that I want it to throw an exception or something saying this does match what was expected.
I don't want to have to validate things like that once deserialized. Same goes for the <car></car> tag I want that to appear always even if there is no information yet I can remove that too and it will be happy with that.
So what tags do I have to add to make my serialization class know that these things are required and if they are not found throw an exception.
