Getting Started

Before starting to use the Winnovative Client for .NET in your applications you first have to install the Winnovative Server. The server can be installed as Azure Cloud Service Worker Role, Azure Cloud Service Web Role, Azure Service Fabric Application, IIS ASP.NET Web Application or Windows Service.

Winnovative Server

Winnovative Server can be downloaded from Winnovative Software Downloads page of the website. Winnovative Server package contains the server files and detailed installation instructions for each platform. You can start by installing Winnovative Server as a Windows Service on the local development machine with default options. In this case the assigned IP address is 127.0.0.1.

After the Winnovative Server was installed, you are ready to use the Winnovative Client Library for .NET Framework in your applications.

C# Code Samples

Copy the C# code lines from the section below to use the HTML to PDF Converter component to create a PDF document from a web page or from a HTML string and save the resulted PDF to a memory buffer for further processing, to a PDF file or send it to browser for download in ASP.NET applications.

The server IP address is assigned during server installation and it can be omitted from HtmlToPdfConverter constructor if the server was installed on the localhost IP address 127.0.0.1 . There are also variants of the constructor accepting an URL instead of IP address if the server was installed as a web service in Azure or in IIS.

At the top of your C# source file add the using WinnovativeClient; statement to make available the Winnovative Client API for your .NET application.

// add this using statement at the top of your C# file
using WinnovativeClient;

To convert a HTML string or an URL to a PDF file you can use the C# code below.

// create the converter object in your code where you want to run conversion
// change the serverIP value if the server was installed on a remote machine
string serverIP = "127.0.0.1";
HtmlToPdfConverter converter = new HtmlToPdfConverter(serverIP);

// convert the HTML string to a PDF file
converter.ConvertHtmlToFile("<b>Hello World</b> from Winnovative !", null, "HtmlToFile.pdf");

// convert HTML page from URL to a PDF file
string htmlPageURL = "http://www.winnovative-software.com";
converter.ConvertUrlToFile(htmlPageURL, "UrlToFile.pdf");

To convert a HTML string or an URL to a PDF document in a memory buffer and then save it to a file you can use the C# code below.

// create the converter object in your code where you want to run conversion
// change the serverIP value if the server was installed on a remote machine
string serverIP = "127.0.0.1";
HtmlToPdfConverter converter = new HtmlToPdfConverter(serverIP);

// convert a HTML string to a memory buffer
byte[] htmlToPdfBuffer = converter.ConvertHtml("<b>Hello World</b> from Winnovative !", null);

// write the memory buffer to a PDF file
System.IO.File.WriteAllBytes("HtmlToMemory.pdf", htmlToPdfBuffer);

// convert an URL to a memory buffer
string htmlPageURL = "http://www.winnovative-software.com";
byte[] urlToPdfBuffer = converter.ConvertUrl(htmlPageURL);

// write the memory buffer to a PDF file
System.IO.File.WriteAllBytes("UrlToMemory.pdf", urlToPdfBuffer);

To convert in your ASP.NET Core and ASP.NET MVC applications a HTML string or an URL to a PDF document in a memory buffer and then send it for download to browser you can use the C# code below.

// create the converter object in your code where you want to run conversion
// change the serverIP value if the server was installed on a remote machine
string serverIP = "127.0.0.1";
HtmlToPdfConverter converter = new HtmlToPdfConverter(serverIP);

// convert a HTML string to a memory buffer
byte[] htmlToPdfBuffer = converter.ConvertHtml("<b>Hello World</b> from Winnovative !", null);

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

To convert in your ASP.NET Web Forms application a HTML string to a PDF document in a memory buffer and then send it for download to browser you can use the C# code below.

// create the converter object in your code where you want to run conversion
// change the serverIP value if the server was installed on a remote machine
string serverIP = "127.0.0.1";
HtmlToPdfConverter converter = new HtmlToPdfConverter(serverIP);

// convert a HTML string to a memory buffer
byte[] htmlToPdfBuffer = converter.ConvertHtml("<b>Hello World</b> from Winnovative !", null);

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