Sign Word Processing with Metadata

Introduction

In this tutorial, we’ll guide you through the process of signing a Word Processing document with metadata using GroupDocs.Signature for .NET. Metadata signing allows you to embed additional information into your document, such as the author’s name, creation date, document ID, and more.

Prerequisites

Before we begin, make sure you have the following:

  • GroupDocs.Signature for .NET library installed.
  • Access to a Word Processing document (e.g., .docx).
  • Basic knowledge of C# programming language.

Import Namespaces

First, you need to import the necessary namespaces to your C# project:

using System;
using System.IO;
using GroupDocs.Signature;
using GroupDocs.Signature.Domain;
using GroupDocs.Signature.Options;

Step 1: Set File Paths

Define the file path of the Word Processing document you want to sign and the output file path where the signed document will be saved.

string filePath = "sample.docx";
string outputFilePath = Path.Combine("Your Document Directory", "SignWordProcessingWithMetadata", "SignedWithMetadata.docx");

Step 2: Initialize Signature Object

Create a Signature object by passing the file path of the document you want to sign.

using (Signature signature = new Signature(filePath))
{
    // Signature operations will be performed here
}

Step 3: Define Metadata Sign Options

Now, let’s create Metadata sign options and add various types of metadata signatures.

MetadataSignOptions options = new MetadataSignOptions();
// Add metadata signatures
options
    .Add(new WordProcessingMetadataSignature("Author", "Mr.Sherlock Holmes")) // String value
    .Add(new WordProcessingMetadataSignature("CreatedOn", DateTime.Now))      // DateTime values
    .Add(new WordProcessingMetadataSignature("DocumentId", 123456))           // Integer value
    .Add(new WordProcessingMetadataSignature("SignatureId", 123.456D))        // Double value
    .Add(new WordProcessingMetadataSignature("Amount", 123.456M))             // Decimal value
    .Add(new WordProcessingMetadataSignature("Total", 123.456F));             // Float value

Step 4: Sign the Document

Now, let’s sign the document with the defined metadata options and save the signed document to the output file path.

SignResult result = signature.Sign(outputFilePath, options);
Console.WriteLine($"\nSource document signed successfully with {result.Succeeded.Count} signature(s).\nFile saved at {outputFilePath}.");

This concludes the process of signing a Word Processing document with metadata using GroupDocs.Signature for .NET.

Conclusion

In this tutorial, we’ve learned how to sign a Word Processing document with metadata using GroupDocs.Signature for .NET. Metadata signing adds valuable information to your documents, enhancing their authenticity and traceability.
