Examples

The following example demonstrates how to use to define eviction policies for cache entries.

using System;
using Cuemon.Runtime.Caching; // for CacheInvalidation

namespace MyApp.Examples;

public class CacheInvalidationExample
{
    public void Demonstrate()
    {
        // Absolute expiration at a specific UTC time
        var absolute = new CacheInvalidation(new DateTime(2025, 12, 31, 23, 59, 59, DateTimeKind.Utc));
        Console.WriteLine(absolute.UseAbsoluteExpiration); // True
        Console.WriteLine(absolute.AbsoluteExpiration);    // 12/31/2025 23:59:59
        Console.WriteLine(absolute.UseSlidingExpiration);  // False
        Console.WriteLine(absolute.UseDependency);         // False

        // Sliding expiration (entry expires after 30 minutes of inactivity)
        var sliding = new CacheInvalidation(TimeSpan.FromMinutes(30));
        Console.WriteLine(sliding.UseSlidingExpiration); // True
        Console.WriteLine(sliding.SlidingExpiration);    // 00:30:00
        Console.WriteLine(sliding.UseAbsoluteExpiration); // False

}
}
