How to serialize a List into XML? [closed]

Answer 1

You can use Linq-to-XML

List Branches = new List();
Branches.Add(1);
Branches.Add(2);
Branches.Add(3);

var branchesXml = Branches.Select(i => new XElement("branch",
                                                    new XAttribute("id", i)));
var bodyXml = new XElement("Branches", branchesXml);
System.Console.Write(bodyXml);

Or create the appropriate class structure and use XML Serialization.

[XmlType(Name = "branch")]
public class Branch
{
    [XmlAttribute(Name = "id")]
    public int Id { get; set; }
}

var branches = new List();
branches.Add(new Branch { Id = 1 });
branches.Add(new Branch { Id = 2 });
branches.Add(new Branch { Id = 3 });

// Define the root element to avoid ArrayOfBranch
var serializer = new XmlSerializer(typeof(List),
                                   new XmlRootAttribute("Branches"));
using(var stream = new StringWriter())
{
    serializer.Serialize(stream, branches);
    System.Console.Write(stream.ToString());
}
