Adding Custom Document Properties in Word

Introduction

Welcome! If you’re exploring Aspose.Words for .NET and want to learn how to add custom document properties to your Word files, you’re in the right place. Custom properties are invaluable for storing additional metadata that built-in properties don’t cover. Whether you need to track document authorization, revision numbers, or specific dates, custom properties can help. In this tutorial, we’ll guide you through the steps to add these properties seamlessly using Aspose.Words for .NET. Let’s get started!

Prerequisites

Before diving into the code, ensure you have the following:

  1. Aspose.Words for .NET Library: Download it here.
  2. Development Environment: An IDE such as Visual Studio.
  3. Basic Knowledge of C#: Familiarity with C# and .NET will be helpful.
  4. Sample Document: Prepare a sample Word document named Properties.docx for modification.

Importing Namespaces

To access the functionalities of Aspose.Words, you’ll need to import the necessary namespaces at the beginning of your code:

using System;
using Aspose.Words;

Step 1: Setting Up the Document Path

Next, let’s define the path to your Word document. This step is essential for locating and opening your Properties.docx file.

// Specify the path to your documents directory.
string dataDir = "YOUR DOCUMENT DIRECTORY";
Document doc = new Document(dataDir + "Properties.docx");

Make sure to replace "YOUR DOCUMENT DIRECTORY" with the actual path to your document.

Step 2: Accessing Custom Document Properties

Now, let’s access the custom document properties of the Word document, where your custom metadata will reside.

CustomDocumentProperties customDocumentProperties = doc.CustomDocumentProperties;

This line gives you access to the collection of custom properties you’ll be working with.

Step 3: Checking for Existing Properties

Before adding new properties, it’s wise to check if a property already exists to avoid duplication.

if (customDocumentProperties["Authorized"] != null) return;

This code checks if the “Authorized” property already exists. If it does, the method exits early, preventing duplicates.

Step 4: Adding a Boolean Property

Let’s add a custom boolean property to indicate whether the document is authorized.

customDocumentProperties.Add("Authorized", true);

This line adds a property named “Authorized” and sets its value to true.

Step 5: Adding a String Property

Next, we’ll specify who authorized the document by adding a string property.

customDocumentProperties.Add("Authorized By", "John Smith");

Feel free to replace “John Smith” with any name you prefer.

Step 6: Adding a Date Property

To track when the document was authorized, let’s add a date property.

customDocumentProperties.Add("Authorized Date", DateTime.Today);

This line adds a property called “Authorized Date” and assigns it today’s date using DateTime.Today.

Step 7: Adding a Revision Number

For version control, we can add a property to keep track of the document’s revision number.

customDocumentProperties.Add("Authorized Revision", doc.BuiltInDocumentProperties.RevisionNumber);

Here, we add an “Authorized Revision” property that holds the document’s current revision number.

Step 8: Adding a Numeric Property

Finally, let’s add a numeric property to store an authorized amount, such as a budget figure.

customDocumentProperties.Add("Authorized Amount", 123.45);

This line adds a property named “Authorized Amount” with a value of 123.45. You can adjust this number as needed.

Conclusion

Congratulations! You’ve successfully added custom document properties to a Word document using Aspose.Words for .NET. These properties are a powerful way to store metadata tailored to your requirements, whether tracking authorization details, revision numbers, or specific amounts.
