Introduction to caching

Here is a basic example of how to use caching:

using System;
using System.Threading;
using SixPack.ComponentModel;
namespace SixPack.Examples
{
	public class MainClass
	{
		public static void Main(string[] args)
		{
			MyTime myTime = new MyTime();

			for (int i = 0; i < 10; i++)
			{
				Console.WriteLine("{0:HH:mm:ss:fffff}", myTime.Get());
				Console.WriteLine("{0:HH:mm:ss:fffff}", myTime.GetNoCache());
				Thread.Sleep(600);
			}
		}
	}

	[Cached]
	public class MyTime : ContextBoundObject
	{
		[CachedMethod(1)]
		public DateTime Get()
		{
			Console.WriteLine("Get invoked.");
			return DateTime.Now;
		}
	
		public DateTime GetNoCache()
		{
			Console.WriteLine("GetNoCache invoked.");
			return DateTime.Now;
		}
	}
}

Result:

Notes

• Without an HttpContext loaded, the class uses a dictionary for caching, therefore cached items will not expire.
• You have to derive from ContextBoundObject to make the Cache work. For examples on how to use caching when you can't do this see AdvancedCaching.
• Your methods have to be non-static. For examples on how to use caching with static methods see AdvancedCaching.
