Start Using HiQPdf

Before using the client library it is necessary to install the HiQPdf Server. The server can run as a Windows Service or as an Azure Cloud Service. The server can be accessed with an IP address and a port number which are assigned when the server is installed.

HiQPdf Server Installation

You can Download HiQPdf Server as a ZIP file and extract it in a root folder on your computer. Follow the detailed instructions in the Installation Guide.pdf document to install the server and get the server IP address that you will use in the client applications. For quick testing you can install the Windows Service on localhost with default options and in this case the assigned IP address is 127.0.0.1.

After server installation you are ready to use the client library in your .NET applications. You can start by copying the C# code below in your application or you can start with the demo applications for .NET from the downloadable product packages.

C# Code Samples for HTML to PDF

The C# code samples below show how to quickly produce PDF documents from HTML pages or HTML code and save the resulting PDF to a memory buffer, to a PDF file or send it to the browser for download when created in ASP.NET applications.

At the top of your C# source file you have to add the using HiQPdfClient; instruction to make the HiQPdfClient namespace available to your application code.

// Include the HiQPdfClient namespace at the top of your C# file
using HiQPdfClient;

You can use the C# code below to convert HTML code or an HTML page from a given URL to a PDF file.

// Create the HTML to PDF converter object
string server_ip_address = "127.0.0.1";
HtmlToPdf converter = new HtmlToPdf(server_ip_address);

// Convert the HTML code to a PDF file
converter.ConvertHtmlToFile("<b>Hello World</b> from HiQPdf !", null, "html_to_file.pdf");

// Convert the HTML page from URL to a PDF file
string urlToConvert = "https://www.hiqpdf.com";
converter.ConvertUrlToFile(urlToConvert, "url_to_file.pdf");

Alternatively you can produce the PDF document in a memory buffer that you can further save to a file on the server.

// Create the HTML to PDF converter object
string server_ip_address = "127.0.0.1";
HtmlToPdf converter = new HtmlToPdf(server_ip_address);

// Convert the HTML code to memory
byte[] htmlToPdfData = converter.ConvertHtmlToMemory("<b>Hello World</b> from HiQPdf !", null);

// Save the PDF data to a file
System.IO.File.WriteAllBytes("html_to_memory.pdf", htmlToPdfData);

// Convert the HTML page from URL to memory
string urlToConvert = "https://www.hiqpdf.com";
byte[] urlToPdfData = converter.ConvertUrlToMemory(urlToConvert);

// Save the PDF data to a file
System.IO.File.WriteAllBytes("url_to_memory.pdf", urlToPdfData);

The C# code below can be used in your ASP.NET Core and ASP.NET MVC applications to convert HTML code to PDF in a memory buffer and then send the PDF data for download to the browser.

// Create the HTML to PDF converter object
string server_ip_address = "127.0.0.1";
HtmlToPdf converter = new HtmlToPdf(server_ip_address);

// Convert the HTML code to memory
byte[] htmlToPdfData = converter.ConvertHtmlToMemory("<b>Hello World</b> from HiQPdf !", null);

FileResult fileResult = new FileContentResult(htmlToPdfData, "application/pdf");
fileResult.FileDownloadName = "html_to_pdf.pdf";
return fileResult;

The C# code below can be used in your ASP.NET Web Forms applications to convert HTML code to PDF in a memory buffer and then send the PDF data for download to the browser.

// Create the HTML to PDF converter object
string server_ip_address = "127.0.0.1";
HtmlToPdf converter = new HtmlToPdf(server_ip_address);

// Convert the HTML code to memory
byte[] htmlToPdfData = converter.ConvertHtmlToMemory("<b>Hello World</b> from HiQPdf !", null);

HttpResponse httpResponse = HttpContext.Current.Response;
httpResponse.AddHeader("Content-Type", "application/pdf");
httpResponse.AddHeader("Content-Disposition",
    String.Format("attachment; filename=html_to_pdf.pdf; size={0}",
    htmlToPdfData.Length.ToString()));
httpResponse.BinaryWrite(htmlToPdfData);
httpResponse.End();
