在 C# 中内联或在静态构造函数中初始化静态变量的区别

Difference initializing static variable inline or in static constructor in C#(在 C# 中内联或在静态构造函数中初始化静态变量的区别)

问题描述

我想知道初始化静态成员内联有什么区别:

I would like to know what is the difference between initializing a static member inline as in:

class Foo
{
    private static Bar bar_ = new Bar();
}

或在静态构造函数中对其进行初始化，如下所示:

or initializing it inside the static constructor as in:

class Foo
{
    static Foo()
    {
        bar_ = new Bar();
    }
    private static Bar bar_;
}

推荐答案

如果你的类型中有一个静态构造函数，它会因为 beforefieldinit 标志不再被应用.

If you have a static constructor in your type, it alters type initialization due to the beforefieldinit flag no longer being applied.

它也会影响初始化顺序 - 变量初始化器都在静态构造函数之前执行.

It also affects initialization order - variable initializers are all executed before the static constructor.

据我所知就是这样.
