Getting Started

Before starting to use the EVO PDF Client for .NET Core in your applications you first have to install the EVO PDF 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.

EVO PDF Server

EVO PDF Server can be downloaded from http://www.evopdf.com/download.aspx#client_server page of the website. EVO PDF Server package contains the server files and detailed installation instructions for each platform. You can start by installing EVO PDF 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 EVO PDF Server was installed, you are ready to use the EVO PDF Client Library for .NET Core in your applications.

C# Code Sample

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 to 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 EvoPdfClient;' statement to make available the EVO PDF Client API for your .NET application.

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

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 EVO PDF !", null, "HtmlToFile.pdf");

// convert HTML page from URL to a PDF file
string htmlPageURL = "http://www.evopdf.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 EVO PDF !", 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.evopdf.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 application 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 EVO PDF !", null);

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