C# Code Samples

Copy the C# code lines from the section below 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 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 EvoPdf.HtmlToPdfClient; statement to make available the EVO HTML to PDF Client API for your .NET application.

// add this using statement at the top of your C# file
using EvoPdf.HtmlToPdfClient;

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;

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 EVO PDF !", null);

HttpResponse httpResponse = HttpContext.Current.Response;
httpResponse.AddHeader("Content-Type", "application/pdf");
httpResponse.AddHeader("Content-Disposition",
