How to a find date differences between two dates using c# datetime and timespan?

Hi Readers,

In this article, You will learn how to find a differences between two dates using c# datetime and timespan.

Scenario: Manger asked you to show how much time taken to finish the whole process of the application and here in application has 5 pages to process.

For this requirement, we are going to use Datetime and TimeSpan classes.

To simplify this scenario, Showing here with for loop,

Program.cs

using System;
using System.Threading;

namespace ConsoleAppNew
{
    class Program
    {
        static void Main(string[] args)
        {
         
           // Hold the startTime
            var startTime = DateTime.Now;

            // For 5 pages i am using for loop
            for(int index = 0; index <5;index++)
            {         
            // To differentiate the time, here used Sleep method.
            Thread.Sleep(1000);

            // Gets only time duration
            TimeSpan timeSpan = DateTime.Now.Subtract(startTime).Duration();

            // To see the timespan in terms of hours, minutes and seconds.
            Console.WriteLine(" Time taken to process the current page " + index + " is " + timeSpan.Hours +" hours "+ timeSpan.Minutes +" minutes "+ timeSpan.Seconds + " seconds.");
            }

    }
      }
}

Output for this program is:

 Time taken to process the current page 0 is 0 hours 0 minutes 1 seconds.
 Time taken to process the current page 1 is 0 hours 0 minutes 2 seconds.
 Time taken to process the current page 2 is 0 hours 0 minutes 3 seconds.
 Time taken to process the current page 3 is 0 hours 0 minutes 4 seconds.

 Time taken to process the current page 4 is 0 hours 0 minutes 5 seconds.

Hoping this article gives you a clear understaing on how to use datetime and timespan to get the required time in terms of hours, minutes and seconds.

How PDF Links works the same way of WebSite Links using ABCPDF Library?

Hi Readers,

Scenario: Read any web site/Page using AddImageUrl function in Abcpdf library but Page/Site has links. How in website links perform the same way in PDF also should work.

Solution: The below code performs the same.

Key Points:

1. If we are not using the below two lines then PDF Links are like normal Text.
  doc.HtmlOptions.AddLinks = true;
  doc.HtmlOptions.LinkPages();

2. An important point to remember is order and the place where to add,

   Either add before the following line like below,
   doc.HtmlOptions.AddLinks = true;
   doc.HtmlOptions.LinkPages();
   int theID = doc.AddImageUrl("https://techinuthan.blogspot.com/"); 
   
     Or the other option is the below sample code,

Sample Code:

using System;

using System.IO;
using WebSupergoo.ABCpdf11;
 
namespace Demos_on_abcpdf
{
    class Program
    {
        static void Main(string[] args)
        {
            string theBasePath = Directory.GetParent(Directory.GetCurrentDirectory()).Parent.FullName;
            string outputFolder = theBasePath + @"\Output\";


            // This Doc class is coming from WebSupergoo.ABCpdf11 namespace.

            Doc doc = new Doc(); 
  
            #region Demo 1 Starts -  Multiple Pages inside single PDF With Links action Perform
            doc.HtmlOptions.AddLinks = true;
            // Converts web page to multiple Images in PDF

            int theID = doc.AddImageUrl("https://techinuthan.blogspot.com/"); 
            while (true)
            {
                if (!doc.Chainable(theID))
                    break;
                doc.Page = doc.AddPage();
                doc.AddImageToChain(theID);
            }
 
            doc.HtmlOptions.LinkPages();
            doc.Save(outputFolder + "ConvertWebPageToMultiplePagesWithLinks.pdf");
            #endregion Demo 1 Ends - Multiple Pages inside single PDF With Links action Perform
 
 
            Console.WriteLine("PDF Generated Successfully");
