By using:

string strContent = YourText;
Regex urlregex = new Regex(@"(http:\/\/([\w.]+\/?)\S*)",
                 RegexOptions.IgnoreCase| RegexOptions.Compiled);
strContent = urlregex.Replace(strContent, 
             "<a href=\"$1\" target=\"_blank\">$1</a>");

You could use a regular expression here to identify where the hyperlink begins and ends (possibly based on the length of the match) Then add in your anchor tags before and after.

see this one, uses regex

private string ConvertUrlsToLinks(string msg) {
    string regex = @"((www\.|(http|https|ftp|news|file)+\:\/\/)[&#95;.a-z0-9-]+\.[a-z0-9\/&#95;:@=.+?,##%&~-]*[^.|\'|\# |!|\(|?|,| |>|<|;|\)])";
    Regex r = new Regex(regex, RegexOptions.IgnoreCase);
    return r.Replace(msg, "<a href=\"$1\" title=\"Click to open in a new window or tab\" target=\"&#95;blank\">$1</a>").Replace("href=\"www", "href=\"http://www");
}
