有关GC的基本问题 [英] Basic question on GC

问题描述

using System;

class Calci
{

    public int Add(int a, int b)
    {

        return (a + b);

    }

    public int Sub(int a, int b)
    {

        return (a - b);

    }

    public int Multi(int a, int b)
    {

        return (a * b);

    }

    public int Divide(int a, int b)
    {

        return (a / b);

    }

}



class GCExample3
{

    public static void Main(string[] args)
    {

        Calci oCalci = new Calci();

        Console.WriteLine("Calci object is now on " + GC.GetGeneration(oCalci) + " Generation");
        Console.WriteLine("call to GC.Collect(0):");
        GC.Collect(0);
        Console.WriteLine("Garbage Collection Occured in 0th Generation:" + GC.CollectionCount(0));
        Console.WriteLine(oCalci.Add(9, 0));
        Console.ReadLine();
    }

}

输出:

output :

Calci object is now on 0 Generation
 call to GC.Collect(0):
Garbage Collection Occured in 0th Generation:1
9

我的问题是:
如果我的calci对象在第0代中被垃圾回收，那么之后它如何调用calci类的方法?

My question is that:
If my calci object is garbage collected in 0th generation then how after that it calls to methods of calci class?

因为您的oCalci对象不是空，所以垃圾收集器无法收集oCalci对象.而且我认为收集的对象是在后台仍未收集的对象，并且我认为收集的对象不是您的oCalci对象，因为如果我不声明oCalci对象，如果我进行垃圾收集，GC也会收集1个对象.

Because your oCalci object is not null, the garbage collector cann''t collect the oCalci object. And I think the collected object is an object in the background, that''s not still collected, and I think the collected object isn''t your oCalci object because if I don''t declare the oCalci object, and if I do a garbace collection, the GC collected 1 object also.
