Import Namespaces

To start using GroupDocs.Comparison for .NET, you need to import the necessary namespaces into your project. Here’s how you can do it:

In your project, add the following namespace references at the top of your code file:

using System;
using System.IO;

These namespaces provide access to essential classes and methods required for document comparison tasks.

Step 1: Check License File Existence

if (File.Exists(Constants.LicensePath))
{

This step checks if the license file exists in the specified path.

Step 2: Set License from Stream

using (FileStream stream = File.OpenRead(Constants.LicensePath))
{
    License license = new License();

Step 3: Handle License Absence

Console.WriteLine("License set successfully.");

If the license is set successfully, this step prints a success message.

                  "\nVisit the GroupDocs site to obtain either a temporary or permanent license. " +
                  "\nLearn more about licensing at https://purchase.groupdocs.com/faqs/licensing. " +
