Regex - Dealing with Groups, C#

Just say you have a string like this one....

Job Posting: 10 Jul 2020 - Closing Date: 26 Jul 2020 Land Administration Legal and Justice Regulatory and Compliance Central & North Coasts Job Title: Senior Analyst Native Title Job Grade / Classification: Clerk Grade 9/10 Employment Type: Temporary role for 24 months Location: Negotia... 

and you want to insert a new line after the date, 26 Jul 2020. 

Details = "Job Posting: 10 Jul 2020 - Closing Date: 26 Jul 2020 Land Administration Legal and Justice Regulatory and Compliance Central & North Coasts Job Title: Senior Analyst Native Title Job Grade / Classification: Clerk Grade 9/10 Employment Type: Temporary role for 24 months Location: Negotia... "; 

  Regex r1 = new Regex(@"(.*Closing Date: \d\d [A-Za-z]* \d\d\d\d)(.*)");

Match match = r1.Match(Details);

if (match.Success && match.Groups.Count == 3 )

{

j.JobDates = match.Groups[1].Value.Trim();

j.Details = match.Groups[2].Value.Trim();

}else{

j.Details = Details ; 

}

Assuming you've created a j object with JobDates and Details properties, you'll end up with something like 

Note, the Groups array element at position 0 is the full text, that's why it starts at element 1. 

JobDates
