Step 2: Import System.IO Namespace

using System.IO;

Now that you have set up the prerequisites and imported the required namespaces, let’s dive into rendering a specified number of consecutive pages from a document using GroupDocs.Viewer for .NET.

Step 1: Define Output Directory

string outputDirectory = "Your Document Directory";

Specify the directory where you want the rendered pages to be saved.

Step 2: Define Page File Path Format

string pageFilePathFormat = Path.Combine(outputDirectory, "page_{0}.html");

Set the format for the file paths of the rendered pages. In this example, the pages will be saved as HTML files with names like “page_1.html”, “page_2.html”, etc.

Step 3: Define Page Range

int[] range = Enumerable.Range(1, 3).ToArray();

Specify the range of consecutive pages you want to render. In this case, we are rendering pages 1 to 3.

using (Viewer viewer = new Viewer(TestFiles.SAMPLE_DOCX))
{
    HtmlViewOptions options = HtmlViewOptions.ForEmbeddedResources(pageFilePathFormat);
    viewer.View(options, range);
}

Create an instance of the Viewer class, passing the path to the document file as a parameter. Then, configure HTML view options and call the View method, specifying the page range to render.

Step 5: Display Rendered Output

Console.WriteLine($"\nSource document rendered successfully.\nCheck output in {outputDirectory}.");
