| Before starting to use the Winnovative HTML to PDF 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 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
which is also the default IP address in the demo client applications from software package.

Getting Started |
|
|
|
After the Winnovative Server was installed, you are ready to use the Winnovative Client Library for .NET in your applications. You can quickly start with
the demo applications from the Demo folder of this package or you can integrate the library in your own project.
To start with your own project, first add a reference to
Winnovative.Client NuGet package. Alternatively you can reference the WinnovativeClient_NetCore.dll library directly
from the Bin folder of the client library ZIP package for .NET Core or the WinnovativeClient.dll library from the Bin folder of the client library ZIP package for .NET Framework.
After the reference to library was added to your project you are now ready to start writing code to convert HTML to PDF in your .NET application

the resulted PDF to a memory buffer for further processing, to a PDF file or send it to browser for download in ASP.NET Core 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.

// 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");

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);
