Introduction

In the realm of .NET development, GroupDocs.Watermark stands out as a powerful tool for managing watermarks, annotations, and more within various document formats. Whether you’re working with PDFs, Word documents, or images, GroupDocs.Watermark for .NET provides a seamless integration that empowers developers to manipulate documents with ease.

Prerequisites

Before diving into the intricacies of using GroupDocs.Watermark for .NET, ensure that you have the following prerequisites in place:

  1. Installation: Make sure you have installed GroupDocs.Watermark for .NET. You can download it from the release page.
  2. Document Preparation: Have a document ready on which you want to perform watermarking or other operations.
  3. Basic Knowledge of C#: Familiarize yourself with C# programming language basics as we’ll be using it to interact with GroupDocs.Watermark API.

Import Namespaces

Before starting with the implementation, it’s crucial to import the necessary namespaces to access the functionality of GroupDocs.Watermark. Below are the required namespaces:

using System;
using System.IO;
using GroupDocs.Watermark.Contents.Pdf;
using GroupDocs.Watermark.Options.Pdf;

Step 1: Load Document

string documentPath = "Your Document Path";
string outputDirectory = "Your Document Directory";
string outputFileName = Path.Combine(outputDirectory, Path.GetFileName(documentPath));
var loadOptions = new PdfLoadOptions();
using (Watermarker watermarker = new Watermarker(documentPath, loadOptions))

In this step, we specify the path to the document we want to work with and create a PdfLoadOptions object for loading PDF documents. Then, we initialize a Watermarker object with the document path and load options.

Step 2: Get PDF Content

PdfContent pdfContent = watermarker.GetContent<PdfContent>();

Here, we obtain the content of the PDF document using the GetContent<PdfContent>() method.

Step 3: Add Attachment

pdfContent.Attachments.Add(File.ReadAllBytes("Your Document Path"), "sample doc", "sample doc as attachment");

This step involves adding an attachment to the PDF document. You need to provide the attachment file bytes, name, and description.

Step 4: Save Changes

watermarker.Save(outputFileName);

Finally, we save the changes made to the document with the added attachment.

Conclusion

GroupDocs.Watermark for .NET offers a robust solution for managing document watermarks and attachments seamlessly. By following the steps outlined above, you can easily integrate watermarking and attachment functionalities into your .NET applications.
