C＃static和const变量内存 [英] C# static and const variables memory

问题描述

得到就怀疑到C＃静态/ const成员/局部变量。只是想知道发生了什么，以分配给未使用的静态/ const成员/地方在C＃中的变量的记忆，是如何在下面的示例场景回收内存？

Got doubts with respect to C# static/const member/local variables. Just want to know what happens to the memory allocated to unused static/const member/local variables in C#, how is the memory reclaimed in the following example scenario?

问题是约相对于静态和常量记忆行为[考虑每个应用程序域的内存块 - 静态存储]这个问题是不是垃圾收集。它是关于内存上发生了什么（也）有记忆

Question is about memory behavior with respect to static and const variables [considering per-App-Domain piece of memory - static storage]? This question is NOT about Garbage Collection. It is about memory and what happens to unused static and const variables that (also) have memory?

意粉代码片段未使用的静态和常量：

Spaghetti Code Snippet:

/// <summary>
/// Skew your data with every-second-and-annoyed updates
/// </summary>
class Skewgle
{
    static Skewgle cloneApele = new Skewgle();
    const Skewgle patentMoto = default(dynamic);
    static int? dontBeEvilMotto = 1998;
    const int ditchMotoToBeEvil = 2014;

    static void Main()
    {
        const Skewgle findYourMailsAlreadyReadBetweenSpamTabs = patentMoto;

        if (findYourMailsAlreadyReadBetweenSpamTabs == null)
        {
            System.Console.WriteLine("findYourMailsAlreadyReadBetweenSpamTabs and patentMoto are null");
        }

        if (cloneApele != null)
        {
            System.Console.WriteLine("cloneApele is not null");
        }

        System.Console.WriteLine("What about dontBeEvilMotto? ditchMotoToBeEvil?");
    }
}

推荐答案

的所有的一个类的静态字段将在类的任何实例/静态方法第一次使用（<初始化之前A HREF =HTTP ：//msdn.microsoft.com/en-us/library/aa645758%28v=vs.71%29.aspx>在C＃规范静态字段初始化）

All static fields of a class will be initialized before first usage of any instance/static method of the class (static field initialization in C# spec ).

静态字段每应用程序域和值将不会被标记为GC到的AppDomain卸载。

Static fields are per Application Domain and value will not be marked for GC till unloading of AppDomain.
