GC.KeepAlive（）取消注释时，仍然只有一个实例，怎么办？ [英] GC.KeepAlive() when this is uncommented, still there is only one instance, how ?

问题描述

在下面的参考线程上，即使我注释了GC.KeepAlive（），我也没有发现任何区别，它阻止了任何其他实例的创建。作者为什么明确提到它的重要方面？

On against to the reference thread below, even if I comment the GC.KeepAlive() there is no difference I find and it blocks the creation of any other instance. Why is it the author explicitly mentioned its important line ?

仅确保一个应用程序实例

推荐答案

如果不这样做，互斥体将在垃圾回收时被销毁，但这不是保证的事件立即发生，这就是为什么它仍然可以长时间工作的原因。

If you don't do this the mutex will be destroyed on garbage collection but this isn't a guaranteed event to happen instantly that's why it can still work for a long time.

我本来会用一个静态的自我来查看第二个答案。

I would have used a static my self see the second answer.
