Deserialize XML to object (need to return a list of objects)

Question

Started practicing with XML and C# and I have an error message of "There is an error in XML document (3,2)". After looking at the file, I can't see anything wrong with it (Mind you, I probably missed something since I'm a noob). I'm using a Console Application for C# right now. I'm trying to return a list of Adventurers and just a side note, the GEAR element is optional. Here is what I have so far:

XML File - Test1

<?xml version="1.0" encoding="utf-8"?>
<Catalog>
    <Adventurer>
        <ID>001</ID>
        <Name>John Smith</Name>
        <Address>123 Fake Street</Address>
        <Phone>123-456-7890</Phone>
        <Gear>
            <Attack>
                <Item>
                    <IName>Sword</IName>
                    <IPrice>15.00</IPrice>
                </Item> 
                <Item>
                    <IName>Wand</IName>
                    <IPrice>20.00</IPrice>
                </Item>         
            </Attack>
            <Defense>
                <Item>
                    <IName>Shield</IName>
                    <IPrice>5.00</IPrice>
                </Item>
        </Defense>  
        </Gear>
    </Adventurer>
    <Adventurer>
        <ID>002</ID>
        <Name>Guy noone likes</Name>
        <Address>Some Big House</Address>
        <Phone>666-666-6666</Phone>
        <Gear></Gear>
    </Adventurer>
</Catalog>

C# Classes

public class Catalog
{
    List<Adventurer> Adventurers { get; set; }
}

public class Adventurer
{
    public int ID { get; set; }
    public string Name { get; set; }
    public string Address { get; set; }
    public string Phone { get; set; }
    public Gear Gear { get; set; }
}

public class Gear
{
    public List<Item> Attack { get; set; }
    public List<Item> Defense { get; set; }
}

public class Item
{
    public string IName { get; set; }
    public decimal IPrice { get; set; }
}

Serialize Function - Where the Problem Occurs at Line 5

Catalog obj = null;
string path = @"C:\Users\Blah\Desktop\test1.xml";
XmlSerializer serializer = new XmlSerializer(typeof(Catalog));
StreamReader reader = new StreamReader(path);
obj = (Catalog)serializer.Deserialize(reader);
reader.Close();

Console.ReadLine();

Answer 1

The issue is the list of Adventurers in Catalog:

<?xml version="1.0" encoding="utf-8"?>
<Catalog>
    <Adventurers> <!-- you're missing this -->
        <Adventurer>
        </Adventurer>
        ...
        <Adventurer>
        </Adventurer>
    </Adventurers> <!-- and missing this -->
</Catalog>

You don't have the wrapping element for the Adventurers collection.

EDIT: By the way, I find the easiest way to build the XML structure and make sure it's compatible is to create the object(s) in C#, then run through the built-in XmlSerializer and use its XML output as a basis for any XML I create rather than forming it by hand.

Answer 2

First, "Adventurers" property is not public, it's inaccessible, I think that the best way to find the error is to serialize your object and then compare the result with your xml file.
