[C＃]在块内部制作对象的实例也在块之外工作？

问题描述

您好。我想知道这是如何工作的：

Hi. Im wondering how this worked:

using System;

namespace ConsoleApplication2
{
    class Program
    {
        public static void Main()
        {
            A kick = null;

            {
                kick = new A();
            } // End of the block 

            kick.HelloFromA(); // How I am able still to access it ? 
        }
    }

    class A
    {
        public void HelloFromA()
        {
            Console.WriteLine("Hello from A");
        }
    }
}

垃圾收集器不应该破坏A对象我的A型参考变量指向？



我尝试过的事情：



在CodeProject.com中提出问题

Shouldn't the gerbage collector destroy the A object to which my reference variable of type A is pointing to ?

What I have tried:

推荐答案

public static void Main()
{
    {
        A kick = null;
        kick = new A();
    }
 
    kick.HelloFromA(); // Here you can't access kick...
}

垃圾收集器在超出范围后清除踢，但你不知道何时（很可能不是立即）。

The garbage collector cleans up kick after it goes 'out of scope' but you just don't know when (most likely not immediately).
