Performance Testing with Large PowerPoint Files
The following example shows how you can test the performance of the GemBox.Presentation component with large presentation files using the Free version of the component.
using BenchmarkDotNet.Attributes;
using BenchmarkDotNet.Engines;
using BenchmarkDotNet.Jobs;
using BenchmarkDotNet.Running;
using GemBox.Presentation;
using System.Collections.Generic;
using System.IO;
[SimpleJob(RuntimeMoniker.Net80)]
[SimpleJob(RuntimeMoniker.Net48)]
public class Program
{
private PresentationDocument presentation;
private readonly Consumer consumer = new Consumer();
public static void Main()
{
BenchmarkRunner.Run<Program>();
}
[GlobalSetup]
public void SetLicense()
{
// If using the Professional version, put your serial key below.
ComponentInfo.SetLicense("FREE-LIMITED-KEY");
// If using Free version and example exceeds its limitations, use Trial or Time Limited version:
// https://www.gemboxsoftware.com/presentation/examples/free-trial-professional/901
this.presentation = PresentationDocument.Load("RandomSlides.pptx");
}

public PresentationDocument Reading()
{

}

End Class
If the Free version limits are exceeded, the component will continue to work in Trial mode if the FreeLimitReached event is handled as shown in the example.
For more information about Trial mode limitations, see the Evaluation and Licensing page.
