Below is the corrected version of this code: public string AutoParseURLAndEmail(string psText) { string lsStrContent = psText; Regex loURLRegex = new Regex(@"(http:\/\/([\w.]+\/?)\S*)", RegexOptions.IgnoreCase | RegexOptions.Compiled); lsStrContent = loURLRegex.Replace(lsStrContent, "<a href="http://$2" rel="nofollow">http://$2</a>"); Regex loEmailRegex = new Regex(@"([a-zA-Z_0-9.-]+\@[a-zA-Z_0-9.-]+\.\w+)", RegexOptions.IgnoreCase | RegexOptions.Compiled); lsStrContent = loEmailRegex.Replace(lsStrContent, "<a href="mailto:$1" rel="nofollow"></a>"); return lsStrContent; } Actually, the code above is incorrect, because it doesn’t grab the original URL and Email to include in the hyperlink (it just creates blank hyperlink).

Below is the corrected version of this code:

public string AutoParseURLAndEmail(string psText)
{
string lsStrContent = psText;
Regex loURLRegex = new Regex(@”(http:\/\/([\w.]+\/?)\S*)”, RegexOptions.IgnoreCase | RegexOptions.Compiled);

lsStrContent = loURLRegex.Replace(lsStrContent, “http://$2“);

Regex loEmailRegex = new Regex(@”([a-zA-Z_0-9.-]+\@[a-zA-Z_0-9.-]+\.\w+)”, RegexOptions.IgnoreCase | RegexOptions.Compiled);

lsStrContent = loEmailRegex.Replace(lsStrContent, ““);
return lsStrContent;
}
