How to Load Metadata from Password Protected Document in .NET

Introduction

In the world of .NET development, managing metadata within documents is crucial for various applications. GroupDocs.Metadata for .NET provides powerful tools to extract, edit, and manage metadata in a straightforward manner. This tutorial will walk you through the process of loading metadata from password-protected documents using GroupDocs.Metadata. ##Prerequisites Before diving into this tutorial, ensure you have the following prerequisites in place:

• Visual Studio: Make sure you have Visual Studio installed on your system.
• GroupDocs.Metadata for .NET: Download and install GroupDocs.Metadata for .NET from the download page.
• Basic Understanding of C#: Familiarity with C# programming language is required to follow along with the code examples.

Import Namespaces

Begin by including the necessary namespaces in your C# project:

using GroupDocs.Metadata.Options;
using System;
using GroupDocs.Metadata;

Step 1: Set Load Options for Password-Protected Document

To load metadata from a password-protected document, specify the load options with the document password:

var loadOptions = new LoadOptions
{
    Password = "YourDocumentPassword"
};

Replace "YourDocumentPassword" with the actual password of your document.

Step 2: Load Metadata from the Document

Now, use the Metadata class to load metadata from the document with the specified load options. Replace "YourInputFile" with the path to your document file (absolute or relative path):

using (var metadata = new Metadata("YourInputFile", loadOptions))
{
    // Extract, edit or remove metadata here
}

Within this using block, you can perform various operations on the loaded metadata. For instance, extracting, editing, or removing specific metadata properties.

Step 3: Access Metadata Properties

Within the using block, you can access metadata properties as needed. For example:

var documentMetadata = (DocMetadata)metadata.GetRootPackage();
Console.WriteLine("Author: " + documentMetadata.Author);
Console.WriteLine("Title: " + documentMetadata.Title);

Replace DocMetadata with the appropriate class based on your document format (e.g., PdfMetadata, WordProcessingMetadata, etc.).
