-
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.
// 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();
