Memcache use in. Net

First, Memcache basic concept (socket server) Essence: Is a hash table stored in memory,the maximum value for key is 255 characters and the longest expiration time is 30 days features: Lazy deletion, no monitoring of data expiration mechanism, to achieve the most basic key-value storage,as soon as the memcache is restarted, the data disappears. Build a cluster: Cluster configuration is implemented through client-side drives, and memcache clusters do not communicate with each other How the client implements the cluster: In the Memcache configuration of multiple servers IP and port list, the client to the key hash processing to get hashcode, this hashcode to the number of machines to take the remainder, the data exist on the corresponding machine, read the same algorithm (simple remainder method, the shortcomings of expansion, Using Redis instead of better)

Basic concept: Memcache is the name of the project, Memcached is the name of the Memcache server that can execute the file

second, how to use: 　 1th Step:(administrator) folder where CD memcache is installed: memcached-d Install start: memcached-d start Uninstall: memcached-d stop memcached-d Uninst All2nd Step:Add Reference bottom is a Memche help class (Forget where copy, not the source forgive me)

Easy to use in your code

 Static voidMain (string[] args) {            //Add, save one dayMemchehelper.set ("TestKey","TestValue", DateTime.Now.AddDays (1)); //Take valueMemchehelper.get ("TestKey"); //DeleteMemchehelper.delete ("TestKey"); }
