DateTimeOffset.Compare() Method in C#

The DateTimeOffset.Compare() method in C# is used to compare two DateTimeOffset objects and indicates whether the first is earlier than the second, equal to the second, or later than the second. It returns an integer value,

• <0 − If val1 is earlier than val2
• 0 − If val1 is the same as val2
• >0 − If val1 is later than val2

Syntax

Following is the syntax −

public static int Compare (DateTimeOffset val1, DateTimeOffset val1);

Above, val1 is the 1^st object to compare, whereas val2 is the 2^nd.

Example

Let us now see an example to implement the DateTimeOffset.Compare() method −

using System;
public class Demo {
   public static void Main() {
      DateTimeOffset dateTimeOffset1 = new DateTimeOffset(2019, 09, 09, 8, 20, 10, new TimeSpan(-5, 0, 0));
      DateTimeOffset dateTimeOffset2 = new DateTimeOffset(2019, 10, 09, 8, 20, 10, new TimeSpan(-5, 0, 0));
      Console.WriteLine("DateTimeOffset1 = {0}", dateTimeOffset1);
      Console.WriteLine("DateTimeOffset2 = {0}", dateTimeOffset2);
      int res = DateTimeOffset.Compare(dateTimeOffset1, dateTimeOffset2);
      // returns <0 since DateTimeOffset1 is earlier than DateTimeOffset2
      Console.WriteLine(res);
   }
}

Output

This will produce the following output −

DateTimeOffset1 = 9/9/2019 8:20:10 AM -05:00
DateTimeOffset2 = 10/9/2019 8:20:10 AM -05:00
-1

Example

Let us now see another example to implement the DateTimeOffset.Compare() method −

using System;
public class Demo {
   public static void Main() {
      DateTimeOffset dateTimeOffset1 = new DateTimeOffset(2019, 09, 09, 8, 20, 10, new TimeSpan(-5, 0, 0));
      DateTimeOffset dateTimeOffset2 = new DateTimeOffset(2019, 09, 09, 8, 20, 10, new TimeSpan(-5, 0, 0));
      Console.WriteLine("DateTimeOffset1 = {0}", dateTimeOffset1);
      Console.WriteLine("DateTimeOffset2 = {0}", dateTimeOffset2);
      int res = DateTimeOffset.Compare(dateTimeOffset1, dateTimeOffset2);
      // returns 0 since DateTimeOffset1 is equal to DateTimeOffset2
      Console.WriteLine(res);
   }
}

Output

This will produce the following output −

DateTimeOffset1 = 9/9/2019 8:20:10 AM -05:00
DateTimeOffset2 = 9/9/2019 8:20:10 AM -05:00
