To save you the math in the accepted answer:

var start = html.IndexOf("<body>") + "<body>".Length;
var end = html.IndexOf("</body>");
var result = html.Substring(start, end - start);

Mind that it's not 100% bulletproof:

  • It will fail on CDATA blocks containing <body>
  • It will fail if you have something like <body lang="en">

So all in all you are probably better off with the Agility Pack, unless you know for sure, which HTML you are working with.

Reading the Html Structure into Html String and Getting the Body Tag content using C# without HtmlAgility packages

       private void Button_Click(object sender, RoutedEventArgs e)
        {
            string filepath = @"C:\Users\Testing\Documents\sample1.txt";
            string htmlString = File.ReadAllText(filepath);
            string htmlTagPattern = "<.*?>";
            Regex oRegex = new Regex(".*?<body.*?>(.*?)</body>.*?", RegexOptions.Multiline);
            htmlString = oRegex.Replace(htmlString, string.Empty);
            htmlString = Regex.Replace(htmlString, htmlTagPattern, string.Empty);
            htmlString = Regex.Replace(htmlString, @"^\s+$[\r\n]*", "", RegexOptions.Multiline);
            htmlString = htmlString.Replace("&nbsp;", string.Empty);
        }

Check out the HTML Agility Pack to do all sorts of HTML manipulation

It gives you an interface somewhat similar to the XmlDocument XML handling interface:

 HtmlDocument doc = new HtmlDocument();
 doc.Load("file.htm");

 HtmlNode bodyNode = doc.DocumentNode.SelectSingleNode("/html/body");

 if(bodyNode != null)
 {
    // do something
 }

Use XML methods, XPath. For more advanced manipulation with html use HTML Agility pack.

If it happens to be XHTML, then you could use XPath.

Its easy enough to pull the page code into a string, and simply search for the occurrence of the string "<body" and the string "</body", and just do a little math to get your value...
