如何使用GC.KeepAlive()以及用于什么目的? [英] How to use GC.KeepAlive() and for what purpose?

问题描述

我们如何使用 GC.KeepAlive() 目的是什么?

How can we use GC.KeepAlive() and what is the purpose?

我使用套接字将文件从终端(Windows-CE)传输到服务器.传输所需时间为8分钟. 5分钟后，Windows-CE关闭(如果未按触摸屏)

I transfer files from terminal (Windows-CE) to Server using Socket. The time needed for transfer is 8 minutes. After 5 minutes the Windows-CE shuts down (if touch screen not pressed)

如果我为此使用GC.KeepAlive()，是否可以解决我的问题?

If I use GC.KeepAlive() for this, does this solve my problem?

推荐答案

您很少需要使用GC.KeepAlive-非常.例如，如果您想防止终结器的副作用过早发生，则可以使用它.我最经常看到它用于 Mutex -保持互斥锁处于活动状态，直到应用程序结束为止，以确保只有一个实例. (在这里using语句实际上更好，但这是另一回事.)

You very rarely need to use GC.KeepAlive - very rarely. You'd use it if you wanted to prevent the side-effect of a finalizer from occurring too early, for example. I've most often seen it used for Mutex - keeping mutex alive until the end of an app to make sure there's only one instance. (A using statement is actually better here, but that's a separate matter.)

不，这听起来与您的情况无关.

And no, it doesn't sound like it's relevant in your situation.
