Prerequisites

Before diving into Aspose.HTML for .NET, you’ll need to ensure that you have the following prerequisites in place:

  1. Development Environment: Make sure you have a .NET development environment set up on your machine. You can download and install Visual Studio or use Visual Studio Code for development.

  2. Aspose.HTML for .NET: Download and install the Aspose.HTML for .NET library from here. You can also get a free trial or purchase a license from here.

  3. Data Directory: Prepare a directory where you will store your HTML files, such as “Your Data Directory” mentioned in the code example.

Import Namespaces

To work with Aspose.HTML for .NET, you need to import the following namespaces into your project:

using Aspose.Html.Rendering.Xps;
using Aspose.Html.Rendering.EpubRenderer;
using System.IO;

These namespaces provide access to the rendering capabilities of Aspose.HTML for .NET and enable you to manipulate HTML and EPUB documents.

Creating and Rendering HTML Documents

Now, let’s break down the provided code example into multiple steps and explain each step:

string dataDir = "Your Data Directory";

// Step 1: Open the EPUB document for reading
using (var fs = File.OpenRead(dataDir + "document.epub"))

// Step 2: Create an XPS rendering device
using (var device = new XpsDevice(dataDir + "document_out.xps"))

// Step 3: Create an EPUB renderer
using (var renderer = new EpubRenderer())
{
    // Step 4: Render the EPUB document to XPS format
    renderer.Render(device, fs);
}

  1. Open the EPUB document for reading: In this step, we open an EPUB document (specified by the file path) for reading using a FileStream. This document will be the source for rendering.

  2. Create an XPS rendering device: We create an XPS rendering device using the XpsDevice class. This device will be used to render the content from the EPUB document into XPS format.

  3. Create an EPUB renderer: We create an instance of the EpubRenderer class. This class provides rendering capabilities specifically tailored for EPUB documents.

  4. Render the EPUB document to XPS format: Finally, we call the Render method of the EpubRenderer class to perform the rendering. The rendered output will be saved as an XPS file at the specified location.

Congratulations! You’ve successfully created and rendered an HTML document using Aspose.HTML for .NET.

Conclusion

In this tutorial, we’ve explored the essential steps to create and render HTML documents using Aspose.HTML for .NET. By following these steps and importing the required namespaces, you can harness the power of Aspose.HTML for .NET in your .NET applications.
