If you want to respond to a post use the "Have a Question or Comment" link next to it, or the "Reply" link to a comment. Don't post questions as solutions - apart from the fact that very few people will bother to read it you will attract reports and downvotes

Solution 2

Using html agility pack you can easily do this.

C#

foreach (HtmlNode node in col)
{
     actuald=actualid + node.Value;
}
File.WriteAllText("E://text.csv",actuald);
Console.WriteLine("Data Converted");
Console.ReadKey();
