How to convert PowerPoint PPTX to PDF using C# in .NET Framework

Sometimes a PDF is just more convenient than a clunky PowerPoint file. Converting between the two has never been easier. Today we will accomplishing this in just a couple of easy steps. First let’s install our Convert Client using NuGet:

Install-Package Cloudmersive.APIClient.NET.DocumentAndDataConvert -Version 1.3.4

Then we just have to call ConvertDocumentPptxToPdf:

using System;
using System.Diagnostics;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Api;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Client;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Model;
namespace Example
{
    public class ConvertDocumentPptxToPdfExample
    {
        public void main()
        {
            // Configure API key authorization: Apikey
            Configuration.Default.AddApiKey("Apikey", "YOUR_API_KEY");
            // Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
            // Configuration.Default.AddApiKeyPrefix("Apikey", "Bearer");
var apiInstance = new ConvertDocumentApi();
            var inputFile = new System.IO.Stream(); // System.IO.Stream | Input file to perform the operation on.
try
            {
                // PowerPoint PPTX to PDF
                byte[] result = apiInstance.ConvertDocumentPptxToPdf(inputFile);
                Debug.WriteLine(result);
            }
            catch (Exception e)
            {
                Debug.Print("Exception when calling ConvertDocumentApi.ConvertDocumentPptxToPdf: " + e.Message );
            }
        }
    }
}

And it’s as simple as that! This function is the most efficient for PPTX to PDF, but if you need more flexibility, you may also use ConvertDocumentAutodetectToPdf, which supports a variety of document and image formats.
