销毁C＃中的结构对象？ [英] Destroying a struct object in C#?

问题描述

我担心的是，在C＃中只引用类型得到垃圾回收有点糊涂了。
这意味着GC挑选只有参考类型的内存取消分配。
那么与值类型发生，因为他们也占用内存堆栈？

I am a bit confused about the fact that in C# only the reference types get garbage collected. That means GC picks only the reference types for memory de-allocation. So what happens with the value types as they also occupy memory on stack ?

推荐答案

一开始，他们是否再堆的堆或部分取决于什么情况下他们的一部分 - 如果他们是引用类型之内，他们将在堆上反正。 （你应该考虑多少你真的关心栈/堆鸿沟无论如何 - 作为埃里克利珀写，这是的基本上实现细节。）

For a start, whether they're on the stack or part of the heap depends on what context they're part of - if they're within a reference type, they'll be on the heap anyway. (You should consider how much you really care about the stack/heap divide anyway - as Eric Lippert has written, it's largely an implementation detail.)

不过，基本值类型的内存回收时上下文被回收 - 所以当栈是由你从方法返回弹出，认为回收整个堆栈帧。同样，如果值类型值实际上是对象的一部分，则当垃圾收集的对象的内存被回收。

However, basically value type memory is reclaimed when the context is reclaimed - so when the stack is popped by you returning from a method, that "reclaims" the whole stack frame. Likewise if the value type value is actually part of an object, then the memory is reclaimed when that object is garbage collected.

简短的回答是，你不必担心它:)（这是假设你没有任何的其他的比内存的后顾之忧，当然 - 如果你已经有了结构与需要发布到本机的手柄引用，这是一个有所不同的场景。）

The short answer is that you don't have to worry about it :) (This assumes you don't have anything other than the memory to worry about, of course - if you've got structs with references to native handles that need releasing, that's a somewhat different scenario.)
