I need to extract a date of birth from a given string. The format is always "ddMMMyy" (for example "22NOV83").

The problem is that there could be other chars before and after the dob. possible inputs are : "DOB: 22NOV83", "CUSTOMER A DOB: 22NOV", "22NOV83 BLA BLA"

I think that by using this Regex:


I can check if a string mathces a date , But how to check if a part of a string mathces a date and than extract it ?

Any help would be appreciated.

Hi Takeshi,

var extractedDates = new List<DateTime>();

  foreach (var s in inputs) {

    var m = Regex.Match(s, @"(\d{2}[A-Za-z]{3}\d{2})");

    if (m.Groups.Count == 1) {

      // No match



    try {


    } catch (FormatException) {

      // Regex matched but something else was wrong, i.e. 98ALS98
