对静态变量的任何锁定机制？ [英] Any lock machanism to static variables ?

问题描述

是否存在锁定静态变量的机制，而其他用户访问它以克服concurreny问题。

例如： - User1访问静态变量，User2& User3应该等到User1释放它。

请帮助。



我尝试过： < br $>


尝试了不同的选项但是需要静态变量但是在并发用户时面临问题。

Is there any machanism to lock static variable while other user accessing it to overcome concurreny issue.
Ex:- User1 accessing static variable, User2 & User3 should wait until it is released by User1.
Please help.

What I have tried:

Tried different options but static variable is required but facing issue while concurrent users.

推荐答案

通常，使用静态变量是一个很好的信号，表明你的设计存在缺陷，但偶尔也需要它们。



最简单的方法是使用lock语句（C＃参考）| Microsoft Docs [ ^ ] - 但请注意，您将对任何致命的拥抱或类似问题负责。



我仔细看看您的代码/设计以及您为什么使用静态变量来代替我自己使用静态变量。

Normally, using a static variable is a good sign that your design is flawed, but they are very occasionally necessary.

The simplest way to do it is to use a lock Statement (C# Reference) | Microsoft Docs[^] - but do be aware that you will be responsible for any deadly embrace or similar problems.

I'd have a close look at your code / design and why exactly you are using static variables for multiuser access instead myself.

您可以使用 Mutex 类。

You can use Mutex class.
