How to Convert SVG to PDF Using C# and VB.NET in ASP.NET Core?

The Syncfusion Essential^® PDF is a feature-rich and high performance .NET PDF library used to create, read, and edit PDF documents programmatically without Adobe dependencies. This guide provides a comprehensive approach to converting SVG files to PDFs using both C# and VB.NET.

Steps to convert SVG to PDF programmatically:

1. Create a New Project: Start a new Console application in .NET Core to facilitate the HTML-to-PDF conversion process.
   
   
2. Install Required Packages: Add the Syncfusion.HtmlToPdfConverter.Net.Windows NuGet package from Nuget.org to your project.
   
   
3. Set Up Your Environment: In the Program.cs file, include these namespaces.
   C#

using Syncfusion.HtmlConverter;
using Syncfusion.Pdf;

VB.NET

Imports Syncfusion.HtmlConverter
Imports Syncfusion.Pdf

4. Implement Conversion Logic: Use the following code example in Program.cs to convert SVG files into PDF documents:
   C#

//Initialize HTML to PDF converter
HtmlToPdfConverter htmlConverter = new HtmlToPdfConverter();
string url = Path.GetFullPath(@"Sample.svg");
//Convert a SVG file to PDF with HTML converter
PdfDocument document = htmlConverter.Convert(url);
//Save the PDF document
// Save the document to a memory stream
MemoryStream stream = new MemoryStream();
document.Save(stream);
// Close the document and release all resources
document.Close(true);
// Write the contents of the memory stream to a file
File.WriteAllBytes("SvgToPDF.pdf", stream.ToArray());

VB.NET

' Initialize HTML to PDF converter
Dim htmlConverter As New HtmlToPdfConverter()
' Get the full path of the SVG file
Dim url As String = Path.GetFullPath("Sample.svg")
' Convert the SVG file to a PDF document using the HTML converter
Dim document As PdfDocument = htmlConverter.Convert(url)
' Create a memory stream to save the PDF document
Dim stream As New MemoryStream()
' Save the PDF document to the memory stream
document.Save(stream)
' Close the PDF document and release all resources
document.Close(True)
' Write the contents of the memory stream to a PDF file
File.WriteAllBytes("SvgToPDF.pdf", stream.ToArray()) 

A complete working sample can be downloaded from SVG_To_PDF.zip
