Convert XML to PDF in C# and VB.NET

C# XML to PDF directly can be a complex challenge. We've found that to convert XML to PDF in C#, it is best to start with XSLT as a transformation temple. XML may be rendered to PDF via HTML(5) using XLST transformations. XLST documents define how XML from a given schema may be converted to an accurate HTML representation and are a well established standard. In short, XLST act as a custom translator from XML to HTML.

Convert XML to PDF in C# and VB.NET

How to Convert XML to PDF in C#

  1. Install XML to PDF Converter C# library
  2. Use Load method to import XSLT transformer template
  3. Convert XML to HTML in C# utilizing Transform method
  4. Render the HTML to PDF with custom rendering options
  5. Export the PDF document to desired location

The resultant HTML string or file may then be rendered as a PDF using the .NET PDF Generator:
