Question

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#.

Thanks for the help beforehand.

Answer 1

Are you saying your starting out with separate values for hour, minute, and am/pm?

    public string Get24HourTime(int hour, int minute, string ToD)
    {           
        int year = DateTime.Now.Year;
        int month = DateTime.Now.Month;
        int day = DateTime.Now.Day;
        if (ToD.ToUpper() == "PM") hour = (hour  % 12) + 12;

        return new DateTime(year, month, day, hour, minute, 0).ToString("HH:mm");
    }
