How to set Date Time format in 24 hours in c#?

Question

Hello,

I have to set date time format in 24 hours.

DateTime dtDeadline = (DateTime)currentResume.PositionDeadlineTime;
dateDeadLine = dtDeadline.ToString("dd MMM yyyy hh:mm:ss");

This will give the results as "03 Dec 2019 01:30:00"  // 12 hours

But I need the results as "03 Dec 2019 13:30:00"   // 24 hours
