Introduction

Welcome to the comprehensive guide on using GroupDocs.Annotation for .NET to enhance your document annotation capabilities. Whether you’re a seasoned developer or just starting out, this tutorial will walk you through each step, ensuring you harness the full potential of this powerful tool.

Prerequisites

Before diving into the tutorial, ensure you have the following prerequisites in place:

  1. GroupDocs.Annotation for .NET: Make sure you have downloaded and installed GroupDocs.Annotation for .NET from the download link.
  2. License: Obtain a valid license for GroupDocs.Annotation. You can either purchase one from here or request a temporary license here.
  3. Documentation: Familiarize yourself with the documentation for GroupDocs.Annotation. It provides detailed insights into the API functionalities.

Import Namespaces

First, let’s import the necessary namespaces to start using GroupDocs.Annotation in your .NET project:

using System;
using System.IO;

Step 1: Check License Path

Ensure that the license file path is correctly set in your project. It should point to the location where your license file is stored.

Step 2: Set License

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

In this step, the code checks if the license file exists at the specified path.

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

If the license file exists, it reads the file stream and sets the license using the SetLicense method.

    Console.WriteLine("License set successfully.");
}
else
{

If the license file does not exist, it prompts the user to obtain a license from the GroupDocs site.

    Console.WriteLine("\nWe do not ship any license with this example. " +
                      "\nVisit the GroupDocs site to obtain either a temporary or permanent license. " +
                      "\nLearn more about licensing at https://purchase.groupdocs.com/faqs/licensing. " +
                      "\nLear how to request temporary license at https://purchase.groupdocs.com/temporary-license.");
