Importing Namespaces

Now that you have the prerequisites in place, you can start working with Aspose.HTML for .NET. Let’s import the necessary namespaces to get you started.

Step 1: Create a New .NET Project

If you haven’t already, create a new .NET project in your preferred development environment.

Step 2: Import Aspose.HTML Namespace

In your .NET project, you need to import the Aspose.HTML namespace. This allows you to access the classes and methods provided by Aspose.HTML.

using Aspose.Html;

Step 3: Initialize Configuration

To configure your Aspose.HTML document, you’ll need to set up some parameters. Here’s how you can do it:

string dataDir = "Your Data Directory";
Configuration configuration = new Configuration();
configuration.GetService<IUserAgentService>().UserStyleSheet = @"
    @page 
    {
        /* Page margins should be not empty to write content inside the margin-boxes */
        margin-top: 1cm;
        margin-left: 2cm;
        margin-right: 2cm;
        margin-bottom: 2cm;
        /* Page counter located at the bottom of the page */
        @bottom-right
        {
            -aspose-content: ""Page "" currentPageNumber() "" of "" totalPagesNumber();
            color: green;
        }
        /* Page title located at the top-center box */
        @top-center
        {
            -aspose-content: ""Document's title"";
            vertical-align: bottom;
        }    
    }";

Step 4: Initialize an Empty Document

Create a new HTML document with the given configuration.

using (HTMLDocument document = new HTMLDocument(configuration))
{
    // Your code for working with the HTML document goes here
}

Step 5: Initialize an Output Device

To render your HTML content, you’ll need to initialize an output device. In this example, we’ll use an XPS device.

using (XpsDevice device = new XpsDevice(dataDir + "output_out.xps"))
{
    // Your code for rendering the document goes here
}

Conclusion
