Using following methods you can download youtube videos directly from your browser without using any software.
1. Retrieve the id video from the link (the code after ‘v=’)
example: http://www.youtube.com/watch?v=NegsNQy1ZoU => NegsNQy1ZoU
2. In your favourite browser go to http://youtube.com/v/{ID video}
example: http://youtube.com/v/NegsNQy1ZoU
3. Link in the address bar will change. Replace ’swf/l.swf’ with ‘get_video’ and press Enter

Just experienc it in your browser.
Do It Progrmatically:
Now we will do it programaticaly using asp.net. Just follow followin steps
1. Create a page named as DownloadUTube.aspx
<body>
<form id=”form1″ runat=”server”>
<div>
<table>
<tr>
<td>YouTube URL: <asp:TextBox ID=”txtUrl” runat=”server”></asp:TextBox></td>
<td><asp:Button ID=”btnSubmit” runat=”server” Text=”Submit” OnClick=”btnSubmit_Click” /></td>
</tr>
<tr>
<td align=”center” colspan=”2″>Example: http://www.youtube.com/watch?v=NegsNQy1ZoU </td>
</tr>
<tr>
<td colspan=”2″><asp:Literal ID=”litResult” runat=”server”></asp:Literal></td>
</tr>
</table>
</div>
</form>
</body>
You have successfully completed 1st step now proceed to 2nd one.
Step 2:
Now in your cSharp file you have to go as follow.
// First of all we will change our utube link to our desired format.
string URL = this.txtUrl.Text;
string VideoId = URL.Substring(URL.IndexOf(‘=’)+1);
URL = @”http://youtube.com/v/” + VideoId;
// Now we will send request to server which will create new link.
WebRequest MyRequest = HttpWebRequest.Create(URL);
WebResponse MyResponse = MyRequest.GetResponse();
// we get newly create link into string RealURL
string RealURL = MyResponse.ResponseUri.ToString();
// Creates an HttpWebRequest with the specified URL.
HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(RealURL);
// Sends the HttpWebRequest and waits for the response.
HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
// Gets the stream associated with the response.
Stream receiveStream = myHttpWebResponse.GetResponseStream();
Encoding encode = System.Text.Encoding.GetEncoding(“utf-8″);
// Pipes the stream to a higher level stream reader with the required encoding format.
StreamReader readStream = new StreamReader(receiveStream, encode);
// Now we will write whole stream to specified. It is the path within your website.
StreamWriter writer = new StreamWriter(Server.MapPath(@”Contents\Videos\YourVideoName.flv”), true);
writer.Write(readStream.ReadToEnd());
writer.Close();
Just go on specified path and u will see the video.
Final saying, if you have any problem about this. write to me. I will try my best to solve it.

Hey Bro you have created a good program………..also there is another way to minimize the code i.e.
string videoID = txtPath.Text.Substring(txtPath.Text.IndexOf(‘=’) + 1);
WebRequest wReq = HttpWebRequest.Create(@”http://youtube.com/v/” + videoID);
WebResponse wRes = wReq.GetResponse();
string originalVdo = wRes.ResponseUri.OriginalString.Replace(“swf/l.swf”, “get_video”);
WebClient wc = new WebClient();
wc.DownloadFile(originalVdo, @”c:\fileName.flv”);
ur work is dam good…………….
