C#单例设计模式的运用《一个小游戏的例子》

由于我在游戏中创建了N个类，有可能完本插入代码，Bety不够，下面就插入《单例设计模式》的代码，及个别类的代码，如果哪里有错误，希望高手指教！
下面插入一个Games类的代吗，也是游戏的主要部分《单例设计模式》

public class Games
{
private Games()

}
private static volatile Games instance;//，Volatile禁止系统微调代码间的调用。这个也很关健。
private static object lockHelper =new object();//这个是一个辅助对象为，单例设计模式加一个双保险、
public static Games GetInstance()
{
if (instance == null)
{
lock (lockHelper)//双保险的实现，经过两层的过虑，还要注意上面《volatile Games instance;>>关健字，Volatile禁止系统微调代码间的调用。
