We will focus on document conversion by using one of the popular libraries in this guide and provide a step-by-step process to convert VSDX to PDF in C#. Users can perform document transformation for Visio file without Microsoft Visio. Further, we develop sample code to generate PDF from VSDX using C# for this tutorial so you can use it in your projects.

Steps to Convert VSDX to PDF in C#

1. Install GroupDocs.Conversion for .NET package from the NuGet package manager in the project
2. Add a reference of GroupDocs.Conversion namespace for performing document conversion
3. Load the VSDX file by creating an object of the Converter class
4. Initialize the PdfConvertOptions class for setting attributes for the output PDF file
5. Consume the Convert method of the Converter class to convert VSDX to PDF using C#, pass PdfConvertOptions instance and output Visio file name as arguments to the Convert method

You can quickly implement the C# VSDX to PDF converter feature with a few lines of code if you follow the preceding instructions. You will not need to install Microsoft Visio for converting a Visio file to PDF document. Install the required package from the given URL and reference it in the code for implementation. After that, use the Converter class to load the input VSDX file and build a PdfConvertOptions object. Finally, use the Convert method to perform document conversion.

Code to Convert VSDX to PDF in C#

We have produced an example to show how to convert VSDX file to PDF in C# by following the above steps. This code serves the purpose of performing basic document conversion to PDF from the Visio file. For complex document transformation, you can set several properties for the output PDF document by consuming an instance of PdfConvertOptions class.

In this tutorial, we focused on the process for converting a Visio file to PDF and how to implement them. We explored document conversion to Excel from a CSV file in one of our recent post, see how to convert CSV to Excel in C# guide for more information.
