普通单例模式

饿汉模式

public class EHan {//创建私有静态对象private static EHan e = new EHan();//私有构造方法private EHan() {}//公共静态，返回值是自身的方法public static EHan GetInsance() {return e;}
}

懒汉模式

public class LanHan {//声明私有静态对象private static LanHan e = null;//私有构造方法	private LanHan() {}//公共静态，返回值是自身的方法public static LanHan GetInstance() {if (e==null){e = new LanHan();}return e;}}

Unity特有单例模式

public class UnityDanLi : MonoBehaviour {//Unity特有单例模式public static UnityDanLi ud = null;//访问方式:(UnityDanLI.ud.Life)public int Lifes = 10;void Start () {ud = this;}// Update is called once per framevoid Update () {}
}
