Dependencies

Assembly	Version
NET Core	6.0 (LTS)
NET Framework	4.8.1
System.Runtime.Caching	8.0.0.1

• A memory caching library which offers timed evictions for stored objects.

• I've also created my own version of Microsoft's memory cache to show how you could roll your own.

• This solution includes a console application for testing the DLL.

Usage

 // Instantiate
 var cache = new CacheHelper<string>();

 // Add an item
 cache.AddOrUpdate("key1", "value1", TimeSpan.FromSeconds(3));
 // Add an item to update
 cache.AddOrUpdate("key3", "value3", DateTime.Now.AddMinutes(1));
 // Update an item
 cache.AddOrUpdate("key3", "updated value3", DateTime.Now.AddMinutes(2));

 // Check expiry
 var dt = cache.GetExpiration("key3");
 Console.WriteLine($"key3 will expire at {dt.Value.ToLongTimeString()}");

 // Check if exists
 Console.WriteLine($"The current cache does {(cache.Contains("key1") ? "" : "not")} contain key1");

 // Refresh the expiration by fetching
 var temp = cache.Get("key1");

 // Delete an item
 cache.Remove("key1");

 // Check if exists after removal
 Console.WriteLine($"The current cache does {(cache.Contains("key1") ? "" : "not")} contain key1");

 // Fetching all keys
 var keys = cache.GetAllKeys();
 foreach (var key in keys) { /* do something */ }

 // Fetching all objects
 var objs = cache.GetCacheAsEnumerable();
 foreach (var obj in objs) { /* do something */ }

 // Clean-up
 cache.Dispose();
