Question

I don’t know how to represent some XML as a C# class. Does anyone have any suggestions as to how to properly map this xml? Here’s my attempt below:

<authenticationResponse>
  <Accounts>
    <AccountId>1</AccountId>
    <AccountId>5</AccountId>
  </Accounts>
</authenticationResponse>


public class authenticationResponse
{
    [XmlElement("Accounts")]
    [DataMember]
    public List<Account> Accounts { get; set; }
}

public class Account
{
    public long id { get; set; }
}

You may load this data via LINQ to XML:

XElement x = XElement.Load("YourFile.xml");
List<Account> accounts = x.Element("Accounts")
                            .Elements("AccountId")
                            .Select(e => new Account { id = (long)e })
                            .ToList();

In this case authenticationResponse class is redundant.

If you’ve got the response in memory (not in a file on your harddrive), you may use this:

string response = ...
XElement x = XElement.Load(new StringReader(response));
