In this code snippet, we will see how to calculate the difference between two dates in C#. We will use DateTime.Subtract() method to calculate the difference between two dates as shown below,

using System;
 
public class Example
{
    public static void Main()
    {
        DateTime date1 = new DateTime(2020, 11, 12);
        DateTime date2 = new DateTime(2020, 11, 15);
        // Calculate difference between date 1 and date 2
        TimeSpan timeSpan = date2.Subtract(date1);
        // Print result
        Console.WriteLine(timeSpan);
        Console.WriteLine("Days difference = {0} ", timeSpan.TotalDays);        
        Console.ReadKey();
    }
}

Output:

3.00:00:00
Days difference = 3
