关于静态成员变量范围的问题 [英] Question about scope of static member variable

问题描述

全部，


当我创建一个带有静态成员变量的类并且在控制台应用程序中引用

类时，它看起来好像每个实例都是

应用程序有自己独立的成员变量副本。


因此，看起来静态类成员的范围是

仅限于在机器上运行的应用程序的特定实例。


这是正确的吗？

All,

When I create a class with a static member variable and reference that
class in a console applicaton it appears as though each instance of the
application has its own separate copy of the member variable.

Therefore, it would appear that the scope of a static class member is
limited to a specific instance of an application that happens to be
running on the machine.

Is this correct?

Thanks,

--Jonathan

每个应用程序都在自己的地址空间中运行，并带有自己的变量，
除非你努力工作（通过共享内存或其他技术）制作

否则。

Every application runs in its own address space with its own variables,
unless you work hard (via shared memory or some other technique) to make
it otherwise.

静态var的范围可以通过ThreadStaticAttribute限制在线程的范围内。

Scope of static var can be limited to the scope of the thread via ThreadStaticAttribute.

OPs问题涉及到多个控制台应用程序的实例

不共享静态变量的值。


- Barry

The OPs question relates to multiple instances of a console application
not sharing the value of a static variable.
