Introduction

In the realm of digital documentation, ensuring authenticity and integrity is paramount. GroupDocs.Signature for .NET provides a robust solution for verifying barcodes within documents. This tutorial delves into the process of verifying barcodes using GroupDocs.Signature for .NET, offering step-by-step guidance for seamless implementation.

Prerequisites

Before embarking on this tutorial, ensure you have the following prerequisites in place:

  1. GroupDocs.Signature for .NET SDK: Download and install the SDK from here.
  2. .NET Framework: Ensure you have the appropriate .NET framework installed on your system.
  3. Document File: Prepare a sample document containing barcodes for verification.

Import Namespaces

Before diving into the implementation, import the necessary namespaces to access the functionalities of GroupDocs.Signature for .NET.

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

Step 1: Set Document File Path

Set the file path of the document that contains the barcodes for verification.

string filePath = "sample_multiple_signatures.docx";

Step 2: Initialize Signature Object

Initialize a Signature object by passing the document file path as a parameter.

using (Signature signature = new Signature(filePath))
{
    // Your code goes here
}

Step 3: Define Verification Options

Define options for barcode verification, such as text to match and match type.

BarcodeVerifyOptions options = new BarcodeVerifyOptions()
{
    AllPages = true, // Verify barcodes on all pages
    Text = "12345", // Text to match within the barcode
    MatchType = TextMatchType.Contains // Match type
};

Step 4: Verify Signatures

Invoke the Verify method on the Signature object, passing the verification options.

VerificationResult result = signature.Verify(options);

Step 5: Handle Verification Result

Handle the verification result to determine the validity of the document signatures.

if (result.IsValid)
{
    // Document verification succeeded
    foreach (BarcodeSignature item in result.Succeeded)
    {
        Console.WriteLine($"\nValid signature is found with text: {item.Text} and type: {item.EncodeType.TypeName}.");
    }
}
else
{
    // Document verification failed
    Helper.WriteError($"\nDocument {filePath} failed verification process.");
}

Conclusion

In conclusion, GroupDocs.Signature for .NET offers a seamless solution for verifying barcodes within documents. By following the steps outlined in this tutorial, you can ensure the authenticity and integrity of your digital documents with ease.
