设计模式总结

一、单例模式

namespace DesignPattern{    public class Single_Pattern    {        private static Single_Pattern single_Pattern = null;        private static object syncObject = new object();        public static Single_Pattern  Instance        {            get            {                lock (syncObject)                {                    if (single_Pattern == null)                    {                        single_Pattern = new Single_Pattern();                    }                }                return single_Pattern;            }        }    }}
