Regular Expression Regex/Match fails if regular expression returns a null

[tdmailbox@yahoo.com]

I have the following regular expression. It works fine if the regex
code returns a match. However if not the .match code fails.

How can I code this so that it skips the match if the regular
expression does not find anything?


Regex reg_unit_num = new Regex("L_unit_n um.*?>(.*?)</td>",
RegexOptions.Ig noreCase);

string unit_num = reg_unit_num.Ma tch(strHTMLPage ).Result("$1");

Regex reg_unit_num = new Regex("L_unit_n um.*?>(.*?)</td>",
RegexOptions.Ig noreCase);
Match m = reg_unit_num.Ma tch(strHTMLPage );
string unit_num = "";
if (m.Success)
{
unit_num = m.Result("$1");
}
