How to serialize HtmlElement object in file stream??

use this code to serialize any object into a file stream ... in your case replace the Object type into HtmlElement

Object obj=new Object();
     XmlSerializer sw = new XmlSerializer(typeof(Object));
     FileStream fs = new FileStream("**Full FilePath**", FileMode.OpenOrCreate);
     sw.Serialize(fs, obj);

hope this helped,good luck.

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.IO;
using System.Runtime.Serialization;
using System.Xml.Serialization;

namespace WindowsFormsApplication1
public partial class Form1 : Form
HtmlElement obj;
public Form1()

private void button1_Click(object sender, EventArgs e)

XmlSerializer sw = new XmlSerializer(typeof(HtmlElement ));
FileStream fs = new FileStream("1.txt", FileMode.OpenOrCreate);
sw.Serialize(fs, obj);

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
HtmlElementCollection col = webBrowser1.Document.GetElementsByTagName("a");
foreach (HtmlElement htmlel in col)
if (htmlel != null)
obj = htmlel;

private void Form1_Load(object sender, EventArgs e)

please see the code.

i am getting error....
System.Windows.Forms.HtmlElement cannot be serialized because it does not have a parameterless constructor.

please help me out. its very urgent.........
thanks a lot, i will check it out.
hmmmmm ... yeah XML serialization is not gonna work for you if the class does not have parameterless constructor :sigh: one way to go around that is to create a wrapper class for the HTMLElement class like the code below and serialize the wrapper class
public class HtmlElementWrapper
           public HtmlElementWrapper()
           { }

           public HtmlElementWrapper(HtmlElement htmlElement)
               this.HtmlElement = htmlElement;

           public HtmlElement HtmlElement
           { get; set; }

or you can use Binary Serialization check out this article for that

Object Serialization using C#

good luck

poooh ... don't know at this point tried it on binary serialization as well and unfortunately HTMLElement is not marked as serializable. at this point the only thing I can ask you is "what is the need for you to serialize an Xml element?? " I mean you can use the HtmlElement.OuterHtml to get the element as plain string and save it, because that is what XMLSerialization basically is going to do.

other than that I hope one of those fine .net developers in here would resolve this issue for you"
