Import Namespaces

In order to utilize GroupDocs.Viewer for .NET effectively, you need to import the necessary namespaces into your project. Follow these steps to import the required namespaces:

using System;
using System.IO;
using GroupDocs.Viewer.Options;

Let’s break down the provided example into multiple steps to understand each component and its functionality.

Step 1: Set Output Directory and File Path

string outputDirectory = "Your Document Directory";
string filePath = Path.Combine(outputDirectory, "output.html");

In this step, we define the output directory where the rendered document will be saved and specify the file path for the output HTML file.

Step 2: Instantiate Viewer Object

using (Viewer viewer = new Viewer(TestFiles.SAMPLE_EML))

Here, we create a new instance of the Viewer class, passing the path of the document to be viewed (in this case, a sample EML file) as a parameter.

Step 3: Define HTML View Options

HtmlViewOptions options = HtmlViewOptions.ForEmbeddedResources(filePath);

In this step, we configure the HTML view options for the document rendering, specifying the output file path for the rendered HTML document.

Step 4: Set DateTime Format and Time Zone Offset

options.EmailOptions.DateTimeFormat = "MM d yyyy HH:mm tt zzz";
options.EmailOptions.TimeZoneOffset = new TimeSpan(1, 0, 0);

Here, we customize the date and time format for email messages and set the time zone offset according to the desired timezone.

Step 5: Render Document

viewer.View(options);

Finally, we call the View method of the Viewer object, passing the configured HTML view options to render the document into HTML format.

Step 6: Display Output Directory

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

This step simply displays a message indicating the successful rendering of the document and provides the path to the output directory where the rendered HTML document is located.
