if you want to remove the html tags then one option is to remove the Regex like given below

                //Your html input
		string htmlsource = "<b>Sample Code!</b><br /><i>this text! </i>";
		//Regex to remove the html tags
		string htmltagsremoved =   Regex.Replace(htmlsource, "<[^>]*>", string.Empty);

Hi slm3003,

This function converts HTML code to plain text.

Any step is commented to explain it better.

You can change or remove unnecessary parts to suite your needs.

public string HTMLToText(string HTMLCode)
{
	// Remove new lines since they are not visible in HTML
	HTMLCode = HTMLCode.Replace("\n", " ");

	// Remove tab spaces
	HTMLCode = HTMLCode.Replace("\t", " ");

	// Remove multiple white spaces from HTML
	HTMLCode = Regex.Replace(HTMLCode, "\\s+", " ");

	// Remove HEAD tag
	HTMLCode = Regex.Replace(HTMLCode, "<head.*?</head>", ""
						, RegexOptions.IgnoreCase | RegexOptions.Singleline);

	// Remove any JavaScript
	HTMLCode = Regex.Replace(HTMLCode, "<script.*?</script>", ""
		 , RegexOptions.IgnoreCase | RegexOptions.Singleline);

	// Replace special characters like &, <, >, " etc.
	StringBuilder sbHTML = new StringBuilder(HTMLCode);
	// Note: There are many more special characters, these are just
	// most common. You can add new characters in this arrays if needed
	string[] OldWords = {"&nbsp;", "&amp;", "&quot;", "&lt;",
   "&gt;", "&reg;", "&copy;", "&bull;", "&trade;"};
	string[] NewWords = { " ", "&", "\"", "<", ">", "®", "©", "•", "™" };
	for (int i = 0; i < OldWords.Length; i++)
	{
		sbHTML.Replace(OldWords[i], NewWords[i]);
	}

	// Check if there are line breaks (<br>) or paragraph (<p>)
	sbHTML.Replace("<br>", "\n<br>");
	sbHTML.Replace("<br ", "\n<br ");
	sbHTML.Replace("<p ", "\n<p ");

	// Finally, remove all HTML tags and return plain text
	return System.Text.RegularExpressions.Regex.Replace(
			sbHTML.ToString(), "<[^>]*>", "");
}
