Sorry But I was looking for Non - WPF version of code.. Is there a way to do it using file streams ?? Youtube videos are in .flv format so if we can convert a youtube url into a .flv file then we need some player to play that file.. but its a big procedure and very complex.. I dont think pure c# code can work out on this issue.. Do you have any other suggestion or any idea?? using WebRequest and WebResponse Classes of System.Net namespace we can only extract the html contents of the youtube video page.. how do we extract only video..??

You can generate a small wrapper html page and load it in the web-browser control. The html page would only contain the <object> tag that is used by youtube page to host Flash player plugin.
As for the actual video data, i suggest that you use Wireshark to capture sample video download session and it would tell you the format of the url that the flash player uses to fetch the data. Opening that url and saving data using WebRequest should give you the flv file.
In short, all you need is to figure out the right url to download.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

This is along the lines of what abmience suggested above:
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;

namespace WindowsFormsApplication1
{
	public class Form1 : Form
	{
		private WebBrowser browser;
		private System.ComponentModel.IContainer components = null;

		protected override void Dispose(bool disposing)
		{
			if (disposing && (components != null))
			{
				components.Dispose();
			}
			base.Dispose(disposing);
		}

		private void InitializeComponent()
		{
			this.browser = new System.Windows.Forms.WebBrowser();
			this.SuspendLayout();
			// 
			// browser
			// 
			this.browser.Dock = System.Windows.Forms.DockStyle.Fill;
			this.browser.Location = new System.Drawing.Point(0, 0);
			this.browser.MinimumSize = new System.Drawing.Size(20, 20);
			this.browser.Name = "browser";
			this.browser.Size = new System.Drawing.Size(284, 262);
			this.browser.TabIndex = 0;
			// 
			// Form1
			// 
			this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
			this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
			this.ClientSize = new System.Drawing.Size(284, 262);
			this.Controls.Add(this.browser);
			this.Name = "Form1";
			this.Text = "Form1";
			this.Load += new System.EventHandler(this.Form1_Load);
			this.ResumeLayout(false);

		}

		public Form1()
		{
			InitializeComponent();
		}

		private void Form1_Load(object sender, EventArgs e)
		{
			browser.DocumentText =@"<html><head><body>
<object style=""height: 344px; width: 425px""><param name=""movie"" value=""http://www.youtube.com/v/trmG0mgrkM8?version=3""><param name=""allowFullScreen"" value=""true""><param name=""allowScriptAccess"" value=""always""><embed src=""http://www.youtube.com/v/trmG0mgrkM8?version=3"" type=""application/x-shockwave-flash"" allowfullscreen=""true"" allowScriptAccess=""always"" width=""425"" height=""344""></object>
			</body></html>";
		}

...note that I just dropped a WebBrowser control named "browser" on my form, then added the code in Form1_Load.

1) There's a couple places the URL appears in the HTML code.
2) These URL's are specifically for embedding the YouTube player in HTML; the URL you get from Internet Explorer when you visit the YouTube web pages is different.
3) You probably want some function, like below, to accept an easy to provider parameter - like the video's ID - and return the complete HTML.

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;

namespace WindowsFormsApplication1
{
	public class Form1 : Form
	{
		private WebBrowser browser;
		private System.ComponentModel.IContainer components = null;

		protected override void Dispose(bool disposing)
		{
			if (disposing && (components != null))
			{
				components.Dispose();
			}
			base.Dispose(disposing);
		}

		private void InitializeComponent()
		{
			this.browser = new System.Windows.Forms.WebBrowser();
			this.SuspendLayout();
			// 
			// browser
			// 
			this.browser.Dock = System.Windows.Forms.DockStyle.Fill;
			this.browser.Location = new System.Drawing.Point(0, 0);
			this.browser.MinimumSize = new System.Drawing.Size(20, 20);
			this.browser.Name = "browser";
			this.browser.Size = new System.Drawing.Size(284, 262);
			this.browser.TabIndex = 0;
			// 
			// Form1
			// 
			this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
			this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
			this.ClientSize = new System.Drawing.Size(284, 262);
			this.Controls.Add(this.browser);
			this.Name = "Form1";
			this.Text = "Form1";
			this.Load += new System.EventHandler(this.Form1_Load);
			this.ResumeLayout(false);

		}

		public Form1()
		{
			InitializeComponent();
		}

		private void Form1_Load(object sender, EventArgs e)
		{
			ShowVideo("Hf5cJDUwMp8");
		}

		private void ShowVideo(string VideoId)
		{
			browser.DocumentText = String.Format(@"<html><head><body>
<object style=""height: 344px; width: 425px""><param name=""movie"" value=""http://www.youtube.com/v/{0}?version=3""><param name=""allowFullScreen"" value=""true""><param name=""allowScriptAccess"" value=""always""><embed src=""http://www.youtube.com/v/{0}?version=3"" type=""application/x-shockwave-flash"" allowfullscreen=""true"" allowScriptAccess=""always"" width=""425"" height=""344""></object>
			</body></html>", VideoId);
		}
	}
}

Great this thing works 4 me.. Can we get a list of such Video Ids on You Tube on a ListBox Control? I think it would be a good Idea to populate many Video Ids on a list box control and then play a video which we want by selecting it from the listbox control.. Overall it was a nice experience for me to remember.. Thanks a lot man! :)
