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 −
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 −
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
