"迫使"垃圾收集 [英] "forcing" garbage collection
问题描述
我正在尝试围绕C＃/ CLR垃圾收集。在一个
ASP.NET项目中，我遇到了问题，因为在我的代码完成很久之后，对象析构函数被另一个线程调用了。我想要
来知道我是否可以立即强制它（当对象超出范围时）
，而不需要返回并添加所有必需的
Dispose（）调用..
public方法（）
{
CustomClass o = new CustomClass（..）;
..
..
..
};
有没有办法强迫当对象超出范围时，与方法相同的线程调用CustomClass析构函数
？
谢谢。
I''m trying to wrap my ming around C#/CLR garbage collection. In an
ASP.NET project, I''m having a problem because an object destructor is
being called by another thread, long after my code is done. I''m wanting
to know if I can force it to happen immediately (when the object goes
out of scope) without going back and adding all of the required
Dispose() calls..
public Method()
{
CustomClass o = new CustomClass(..);
..
..
..
};
Is there a way to "force" the CustomClass destructor to be called right
when the object goes out of scope, by the same thread as the Method?
Thanks.

有办法。
但正确的方法解决这个问题就是调用Dispose（）。使用
使用声明（首选），或明确调用Dispose（）。
不要通过添加更多错误来修复错误代码。如果这意味着必须返回
并重写一堆没有正确处理的代码，那么就是
。

There is a way.
But the right way to solve this issue is to call Dispose(). Either use
the "using" statement (preferable), or call Dispose() explicitly.
Don''t fix buggy code by adding more bugs. If that means having to go back
and rewrite a bunch of code that wasn''t dispoing of things properly, so be
it.

destructor = finalizer？
destructor = finalizer ?
是
由另一个线程调用，
is
being called by another thread,
有些代码显式调用终结器吗？
Some code explicit calling a finalizer ?

没有返回并添加所有必需的
Dispose（）调用..
public方法（）
{
CustomClass o = new CustomClass（..）;
..

Dispose用于非托管资源。
垃圾收集用于托管资源。
如果对象只保存托管资源，那么让GC做它想要做的事情时它会做什么。
如果对象拥有非托管资源然后使用
Dispose模式。

Dispose is for unmanaged resources.
Garbage collection is for managed resources.
If the object only holds managed resources then let the GC do
what it wants to do when it want to do it.
If the object holds unmanaged resources then use the
Dispose pattern.

Dispose也很有用当管理时资源实际上是一个OS
资源，例如套接字。在这种情况下，明确地处理插座
可以在两台不同的机器上释放操作系统资源。
Mike。
Dispose is also useful when the "managed" resource is actually an OS
resource such as a socket. In this case explicitly disposing the socket
frees up OS resources on two different machines.
