This basic tutorial focuses on how to merge HTML files to PDF in C#. It covers how to configure the library in your environment and the step-by-step process followed by a working sample code to combine HTML to PDF in C#. Moreover, you do not need to install any other tool or application to work with this feature.
Steps to Merge HTML Files to PDF in C#
- Install Aspose.HTML for .NET API to merge the HTML files
- Load multiple HTML files using a separate HTMLDocument class object for each file
- Create an HTMLRenderer class object
- Initialize a PdfDevice class instance
- Merge the source HTML files into one PDF document
These steps present the complete process to merge multiple HTML files into one PDF in C#. First of all, configure the system environment to process the HTML files. Then proceed to load the source HTML files and append them together as a PDF document.
Code to Merge HTML Files to PDF in C#
| using Aspose.Html; | |
| using Aspose.Html.Rendering; | |
| using Aspose.Html.Rendering.Pdf; | |
| namespace AsposeProjects | |
| { | |
| class Program | |
| { | |
| static void Main(string[] args) // Main function to merge HTML files in C# | |
| { | |
| // Initialize license | |
| License lic = new License(); | |
| lic.SetLicense("Aspose.Total.lic"); | |
| // Load HTML documents to merge | |
| using (var document1 = new HTMLDocument("page1.html")) | |
| using (var document2 = new HTMLDocument("page2.html")) | |
| using (var document3 = new HTMLDocument("page3.html")) | |
| { | |
| // Create HTML Renderer class object | |
| using (HtmlRenderer renderer = new HtmlRenderer()) | |
| { | |
| // Initialize PdfDevice | |
| using (var device = new PdfDevice("Combine.pdf")) | |
| { | |
| // Merge HTML documents to PDF | |
| renderer.Render(device, document1, document2, document3); | |
| } | |
| } | |
| } | |
| System.Console.WriteLine("Done"); | |
| } | |
| } | |
| } |
The code snippet above is a bare-minimum sample to demonstrate the feature to combine multiple HTML files into one PDF in C#. Whereas, you can change the number of input files to any other number of files as required into a single PDF file. The Render() method has several overload constructors where different parameters like a maximum time limit or the list of input files can be specified as per your requirements.
