问题描述

什么是单例，我应该在什么时候使用它?

What is a Singleton and when should I use it?

推荐答案

单例是一个类，它只允许创建自己的一个实例 - 并提供对所述实例的简单、轻松的访问.单例前提是跨软件开发的一种模式.

A singleton is a class which only allows one instance of itself to be created - and gives simple, easy access to said instance. The singleton premise is a pattern across software development.

有一个 C# 实现在 C# 中实现单例模式"，涵盖了大部分您需要了解的内容 - 包括一些关于线程安全的好建议.

There is a C# implementation "Implementing the Singleton Pattern in C#" covering most of what you need to know - including some good advice regarding thread safety.

老实说，您很少需要实现单例 - 在我看来，它应该是您应该注意的事情之一，即使它不经常使用.

To be honest, It's very rare that you need to implement a singleton - in my opinion it should be one of those things you should be aware of, even if it's not used too often.
