To retrieve Year, Month and Day

How to retrieve year, month and day from the file name like MONTUE-API-202310031200340313.TXT

Below is the pattern which will not changed

MONTUE-API-{YEAR}{MONTH}{DAY}{TIMESTAMP}.TXT

Solution

  • I have used substring as commented by Johnathan Barclay in the question to achieve my desired result

    var output = input.Substring(11, 8);
