Deserialize nested XML element into class in C#

Building on Ilya's answer:

This can be optimized slightly, since there is already a loaded node: there is no need to pass the xml down to a string (using vehicle.ToString()), only to cause the serializer to have to re-parse it (using a StringReader).

Instead, we can created a reader directly using XNode.CreateReader:

private static T Deserialize<T>(XNode data) where T : class, new(){    if (data == null)        return null;    var ser = new XmlSerializer(typeof(T));    return (T)ser.Deserialize(data.CreateReader());}

Or if data is a XmlNode, use a XmlNodeReader:

private static T Deserialize<T>(XmlNode data) where T : class, new(){    if (data == null)        return null;    var ser = new XmlSerializer(typeof(T));    using (var xmlNodeReader = new XmlNodeReader(data))    {        return (T)ser.Deserialize(xmlNodeReader);    }}

We can then use:

var vehicle = XDocument.Parse(xml)                       .Descendants("Vehicle")                       .First();Vehicle v = Deserialize<Vehicle>(vehicle);

I'm not aware of the full context of your problem, so this solution might not fit into your domain. But one solution is to define your model as:

[XmlRoot("Vehicle")] //<-- optionalpublic class Vehicle{    public string Colour { get; set; }    public string NumOfDoors { get; set; }    public string BodyStyle { get; set; }}

and pass specific node into Deserialize method using LINQ to XML:

var vehicle = XDocument.Parse(xml)                       .Descendants("Vehicle")                       .First();Vehicle v = Deserialize<Vehicle>(vehicle.ToString());//display contents of v Console.WriteLine(v.BodyStyle);   //prints HatchbackConsole.WriteLine(v.Colour);      //prints BlueConsole.WriteLine(v.NumOfDoors);  //prints 3
