要实现一个Singleton Class, 至少需要做以下四个步骤: 1. 为Singleton Object实现一个静态实例, 初始化, 然后设置成nil. 2. 实现一个实例构造方法(通常命名为 sharedInstance 或者 sharedManager)检查上面声名的静态实例是否为nil, 如果是则新建并返回一个本类实例. ...

instance = new SingletonPattern1();这一块可以扩展，直接创建类，也可以创建借口，或直接载入dll等 单例模式是我们学习设计模式的第一课，这个代码已经无懈可击了，代码参考 using System; namespace SingletonPattern { public class SingletonPattern1 { /// ///单例锁对象 /// private static...
