GlynnTucker.Cache QuickStart


The GlynnTucker.Cache assembly provides a data structure for caching slow data retrievals, for example data retrieved from a database server over the network. Think of it as a Hashtable that can automatically expire its data after a set amount of time or a specified period of inactivity, on a per-object basis. It is written in C# and dual licensed under the GPL/MPL, it should work with any .NET language.


As with any other assembly, add the assembly as a reference to your project. Add the statement

using GlynnTucker.Cache;
to your source files as needed.

Usage: static methods.

The easiest way to use the cache is by calling the static methods provided.

	Cache.AddContext("sample"); // Create a cache to store data
	string exampledotcom = new System.IO.StreamReader(
	Cache.Add("sample", "", exampledotcom); // Add a simple string
	Cache.Add("sample", 2, "string2", DateTime.Now.AddHours(1)); // Add a string with an expiration time. The entry will be removed in one hour.
	Cache.Add("sample", 3, "string3", TimeSpan.FromMinutes(5)); // Add a string with a sliding expiration. The entry will be removed once it hasn't been accessed for 5 minutes.

	Cache.Add("sample", 10, new System.Text.StringBuilder()); // Any type can be added.
	string s = (string)Cache.Get("sample", 3); // Example of retrieval
	Cache.ClearContext("sample"); // Delete all entries immediately.

Usage: create an instance.

For a cleaner design on complex projects, you can create an instance of an ICache.

	ICache c = new GlynnTucker.Cache.SimpleMemoryCache();
	string example = new System.IO.StreamReader(

	c.Add(1, "string1");
	c.Add(2, example, DateTime.Now.AddHours(1));
	string s2 = (string)c.Get(2);
