C# Program to Add Two TimeSpan

The TimeSpan structure in C# represents a time interval and provides methods to perform arithmetic operations. You can add two TimeSpan objects using the Add() method or the + operator to get the combined duration.

Syntax

Following is the syntax for adding two TimeSpan objects using the Add() method −

TimeSpan result = timespan1.Add(timespan2);

You can also use the + operator for addition −

TimeSpan result = timespan1 + timespan2;

Using the Add() Method

The Add() method returns a new TimeSpan that represents the sum of two time intervals −

using System;

public class Demo {
   public static void Main() {
      TimeSpan t1 = TimeSpan.FromMinutes(1);
      TimeSpan t2 = TimeSpan.FromMinutes(2);
      Console.WriteLine("First TimeSpan: " + t1);
      Console.WriteLine("Second TimeSpan: " + t2);
      
      // Adding using Add() method
      TimeSpan res = t1.Add(t2);
      Console.WriteLine("Resultant TimeSpan: " + res);
   }
}

The output of the above code is −

First TimeSpan: 00:01:00
Second TimeSpan: 00:02:00
Resultant TimeSpan: 00:03:00

Using the + Operator

The + operator provides a more intuitive way to add TimeSpan objects −

using System;

public class Demo {
   public static void Main() {
      TimeSpan hours = TimeSpan.FromHours(2);
      TimeSpan minutes = TimeSpan.FromMinutes(30);
      TimeSpan seconds = TimeSpan.FromSeconds(45);
      
      Console.WriteLine("Hours: " + hours);
      Console.WriteLine("Minutes: " + minutes);
      Console.WriteLine("Seconds: " + seconds);
      
      // Adding using + operator
      TimeSpan total = hours + minutes + seconds;
      Console.WriteLine("Total Time: " + total);
   }
}

The output of the above code is −

Hours: 02:00:00
Minutes: 00:30:00
Seconds: 00:00:45
Total Time: 02:30:45

Adding Different TimeSpan Units

You can create TimeSpan objects from various time units and add them together −

using System;

public class Demo {
   public static void Main() {
      TimeSpan days = TimeSpan.FromDays(1);
      TimeSpan hours = TimeSpan.FromHours(5);
      TimeSpan minutes = TimeSpan.FromMinutes(30);
      
      Console.WriteLine("Days: " + days);
      Console.WriteLine("Hours: " + hours);
      Console.WriteLine("Minutes: " + minutes);
      
      TimeSpan totalTime = days + hours + minutes;
      Console.WriteLine("Combined Duration: " + totalTime);
      Console.WriteLine("Total Days: " + totalTime.TotalDays);
      Console.WriteLine("Total Hours: " + totalTime.TotalHours);
   }
}

The output of the above code is −

Days: 1.00:00:00
Hours: 05:00:00
Minutes: 00:30:00
Combined Duration: 1.05:30:00
Total Days: 1.2291666666666667
Total Hours: 29.5

Conclusion

Adding TimeSpan objects in C# can be done using either the Add() method or the + operator. Both approaches return a new TimeSpan representing the combined duration, making it easy to perform time calculations in your applications.
