title: Converting AM/PM time to standard time format hh:mm in C#
body: <p>In my ASP.NET web form I have 3 fields - hour, minute and am/pm drop down. How can I get the values of those 3 fields into one variable and then convert the am/pm hour to standard 24 hour time like 05:20PM = 17:20. This needs to be done in C#.</p>
  
  <p>Thanks for the help beforehand.</p>
