C# Weather App (Help please)...

Question

I'm trying to develop a very simple C# application that should be able to tell the user the current temperature using the zip-code or city name. I don't have any knowledge on how XML works. I can only work with C#. So can someone please guide me with this.
I've looked everywhere and the codes involve really complex methods. I just want the temperature for the user in a few lines of code if possible.
Thank you!

Here is code to serialize and deserialize the data.  There are lot of methods to read and write XML.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Xml;
using System.Xml.Serialization;
using System.Xml.Schema;
using System.IO;
namespace WindowsFormsApplication1
public partial class Form1 : Form
const string FILENAME = @"c:\temp\test1.xml";
Current current = null;
public Form1()
InitializeComponent();
current = new Current()
city = new City()
name = "London",
id = 2643743,
coord = new Coord() { lat = 51.51, lon = -0.13 },
country = "GB",
sun = new Sun() { set = DateTime.Parse("2015-02-09T17:04:38"), rise = DateTime.Parse("2015-02-09T07:24:47") }
temperature = new Temperature() { value = 275.75, unit = "kelvin", max = 275.75, min = 275.75}
XmlSerializer serializer = new XmlSerializer(typeof(Current));
StreamWriter writer = new StreamWriter(FILENAME);
serializer.Serialize(writer, current);
writer.Flush();
writer.Close();
writer.Dispose();
XmlSerializer xs = new XmlSerializer(typeof(Current));
XmlTextReader reader = new XmlTextReader(FILENAME);
Current readCurrent = (Current)xs.Deserialize(reader);
[Serializable, XmlRoot("Current")]
public class Current
public City city {get;set;}
public Temperature temperature { get; set; }
[XmlRoot(ElementName = "city")]
public class City
[XmlAttribute("name")]
public string name {get;set;}
[XmlAttribute("id")]
public int id {get;set;}
public Coord coord { get; set; }
public string country { get; set; }
public Sun sun { get; set; }
[XmlRoot(ElementName = "coor")]
public class Coord
[XmlAttribute("lat")]
public double lat {get;set;}
[XmlAttribute("lon")]
public double lon {get;set;}
[XmlRoot(ElementName = "sun")]
public class Sun
[XmlAttribute("set")]
public DateTime set {get;set;}
[XmlAttribute("rise")]
public DateTime rise {get;set;}
[XmlRoot(ElementName = "temperature")]
public class Temperature
[XmlAttribute("value")]
public double value { get; set; }
[XmlAttribute("unit")]
public string unit { get; set; }
[XmlAttribute("max")]
public double max { get; set; }
[XmlAttribute("min")]
public double min { get; set; }
