A TimeSpan value can be represented as [-]d.hh:mm:ss.ff, where the optional minus sign indicates a negative time interval, the d component is days, hh is hours as measured on a 24-hour clock, mm is minutes, ss is seconds, and ff is fractions of a second. The value of the TimeSpan.Hours property is the hours component, hh.

The TimeSpan.Hours property represents whole hours, whereas the TimeSpan.TotalHours property represents whole and fractional hours.

This example demonstrates using the TimeSpan.Hours property.

using System;
public class TimeSpanPropertiesExampleOne {
   public static void Main() {
      TimeSpan ts = new TimeSpan((Int64)10e12+3456789);
      Console.WriteLine(ts.ToString());
      Console.WriteLine("Hours: {0}", ts.Hours );
   }
}

The output is
