Convert XML String to Object

[Originally Posted By]: http://stackoverflow.com/questions/3187444/convert-xml-string-to-object

You have two possibilities.

Method 1. XSD tool


Suppose that you have your XML file in this location C:\path\to\xml\file.xml

  1. Open Developer Command Prompt
    You can find it in Start Menu > Programs > Microsoft Visual Studio 2012 > Visual Studio Tools Or if you have Windows 8 can just start typing Developer Command Prompt in Start screen
  2. Change location to your XML file directory by typing cd /D "C:\path\to\xml"
  3. Create XSD file from your xml file by typing xsd file.xml
  4. Create C# classes by typing xsd /c file.xsd

And that’s it! You have generated C# classes from xml file in C:\path\to\xml\file.cs

Method 2 – Paste special


Required Visual Studio 2012+ with .Net Framework >= 4.5 as project target

  1. Copy content of your XML file to clipboard
  2. Add to your solution new, empty class file (Shift+Alt+C)
  3. Open that file and in menu click Edit > Paste special > Paste XML As Classes
    enter image description here

And that’s it!

Usage


Usage is very simple with this helper class:

using System;
using System.IO;
using System.Web.Script.Serialization; // Add reference: System.Web.Extensions
using System.Xml;
using System.Xml.Serialization;

namespace Helpers
{
    internal static class ParseHelpers
    {
        private static JavaScriptSerializer json;
        private static JavaScriptSerializer JSON { get { return json ?? (json = new JavaScriptSerializer()); } }

        public static Stream ToStream(this string @this)
        {
            var stream = new MemoryStream();
            var writer = new StreamWriter(stream);
            writer.Write(@this);
            writer.Flush();
            stream.Position = 0;
            return stream;
        }


        public static T ParseXML<T>(this string @this) where T : class
        {
            var reader = XmlReader.Create(@this.Trim().ToStream(), new XmlReaderSettings() { ConformanceLevel = ConformanceLevel.Document });
            return new XmlSerializer(typeof(T)).Deserialize(reader) as T;
        }

        public static T ParseJSON<T>(this string @this) where T : class
        {
            return JSON.Deserialize<T>(@this.Trim());
        }
    }
}

All you have to do now, is:

public class JSONRoot
{
    public catalog catalog { get; set; }
}
// ...

string xml = File.ReadAllText(@"D:\file.xml");
var catalog1 = xml.ParseXML<catalog>();

string json = File.ReadAllText(@"D:\file.json");
var catalog2 = json.ParseJSON<JSONRoot>();
