TimeSpan.Subtract() Method in C#


The TimeSpan.Subtract() method in C# is used to return a new TimeSpan object whose value is the difference between the specified TimeSpan object and this instance.

Syntax

The syntax is as follows −

public TimeSpan Subtract (TimeSpan span);

Above, the parameter span is the time interval to be subtracted.

Example

Let us now see an example −

 Live Demo

using System;
public class Demo {
   public static void Main(){
      TimeSpan span1 = TimeSpan.FromTicks(1);
      TimeSpan span2 = new TimeSpan(1);
      TimeSpan span3 = TimeSpan.FromHours(1);
      TimeSpan span4 = TimeSpan.FromMilliseconds(1);
      TimeSpan span5 = TimeSpan.FromMinutes(1);
      TimeSpan span6 = TimeSpan.FromMinutes(1);
      Console.WriteLine("TimeSpan1 = "+span1);
      Console.WriteLine("TimeSpan2 = "+span2);
      Console.WriteLine("TimeSpan3 = "+span3);
      Console.WriteLine("TimeSpan4 = "+span4);
      Console.WriteLine("TimeSpan5 = "+span5);
      Console.WriteLine("Result (Comparison of span1 and span2) = "+TimeSpan.Compare(span1, span2));
      Console.WriteLine("Result (Comparison of span2 and span3) = "+TimeSpan.Compare(span2, span3));
      Console.WriteLine("Result (Comparison of span1 and span3) = "+TimeSpan.Compare(span1, span3));
      Console.WriteLine("Result (Comparison of span3 and span4) = "+TimeSpan.Compare(span3, span4));
      Console.WriteLine("Result (Comparison of span4 and span5) = "+TimeSpan.Compare(span4, span5));
      TimeSpan res1 = span1.Subtract(span2);
      TimeSpan res2 = span2.Subtract(span2);
      Console.WriteLine("Result = "+res1);
      Console.WriteLine("Result = "+res2);
   }
}

Output

This will produce the following output −

TimeSpan1 = 00:00:00.0000001
TimeSpan2 = 00:00:00.0000001
TimeSpan3 = 01:00:00
TimeSpan4 = 00:00:00.0010000
TimeSpan5 = 00:01:00
Result (Comparison of span1 and span2) = 0
Result (Comparison of span2 and span3) = -1
Result (Comparison of span1 and span3) = -1
Result (Comparison of span3 and span4) = 1
Result (Comparison of span4 and span5) = -1
Result = 00:00:00
Result = 00:00:00

Example

Let us now see another example −

 Live Demo

using System;
public class Demo {
   public static void Main(){
      TimeSpan span1 = TimeSpan.FromTicks(1500);
      TimeSpan span2 = new TimeSpan(2, 40, 55);
      TimeSpan span3 = TimeSpan.FromHours(5);
      TimeSpan span4 = TimeSpan.FromMilliseconds(1000);
      TimeSpan span5 = TimeSpan.FromMinutes(50);
      TimeSpan span6 = TimeSpan.FromMinutes(50);
      Console.WriteLine("TimeSpan1 = "+span1);
      Console.WriteLine("TimeSpan2 = "+span2);
      Console.WriteLine("TimeSpan3 = "+span3);
      Console.WriteLine("TimeSpan4 = "+span4);
      Console.WriteLine("TimeSpan5 = "+span5);
      Console.WriteLine("Result (Comparison of span1 and span2) = "+TimeSpan.Compare(span1, span2));
      Console.WriteLine("Result (Comparison of span2 and span3) = "+TimeSpan.Compare(span2, span3));
      Console.WriteLine("Result (Comparison of span1 and span3) = "+TimeSpan.Compare(span1, span3));
      Console.WriteLine("Result (Comparison of span3 and span4) = "+TimeSpan.Compare(span3, span4));
      Console.WriteLine("Result (Comparison of span4 and span5) = "+TimeSpan.Compare(span4, span5));
      TimeSpan res1 = span1.Subtract(span2);
      TimeSpan res2 = span2.Subtract(span2);
      Console.WriteLine("Result = "+res1);
      Console.WriteLine("Result = "+res2);
   }
}

Output

This will produce the following output −

TimeSpan1 = 00:00:00.0001500
TimeSpan2 = 02:40:55
TimeSpan3 = 05:00:00
TimeSpan4 = 00:00:01
TimeSpan5 = 00:50:00
Result (Comparison of span1 and span2) = -1
Result (Comparison of span2 and span3) = -1
Result (Comparison of span1 and span3) = -1
Result (Comparison of span3 and span4) = 1
Result (Comparison of span4 and span5) = -1
Result = -02:40:54.9998500
Result = 00:00:00
