Timespan shows the length of time.To get the minimum value of TimeSpan, use the following property.TimeSpan.MinValueExample Live Demousing System; using System.Linq; public class Demo {    public static void Main() {       Console.WriteLine(TimeSpan.MinValue);    } }Output-10675199.02:48:05.4775808

Set two dates.DateTime date1 = new DateTime(2018, 7, 15, 08, 15, 20); DateTime date2 = new DateTime(2018, 8, 17, 11, 14, 25);Now, get the difference between two dates.TimeSpan ts = date2 - date1;Get the result i.e. the difference in hours.ts.TotalHoursLet us see the complete code.Example Live Demousing System; using System.Linq; public ...
