推荐答案

最常见的模式是使用Singleton模式.由于您还没有表示语言，所以我假设您在这里指的是C#-如果不是，则大多数OO语言的原理仍然相同.

The most common pattern for doing this is to use the Singleton pattern. As you haven't indicated a language, I'm going to assume that you are referring to C# here - if not, the principles are still the same in most OO languages.
