Regular expression to detect exactly “071-XXXXXXX” where X is a digit

Here your are:

Regex regEx = new Regex(@"^071-[0-9]{7}$");

But it will not execute // do something for your sample code, because it's missing the hyphen.

Answer 2

try this

string phoneNumber = "071-2954900";
Regex regEx = new Regex(@"071[-][\d]{7}");
if (regEx.IsMatch(phoneNumber))
{
      //do something
}

^071-.{7,7}$ This regex will match 071-&7digit number for ex:071-9864527

Answer 4

This will match the phone number even with or without the "-"

 Regex regEx = new Regex(@"^\d{3}\-?\d{7}$");
