需要C#代码的说明 [英] Need with explanation for C# Code

问题描述

提供2个班级:

Given 2 classes:

public class SomePublisher
{
public event EventHandler SomeEvent;
}
 
public class SomeSubscriber
{
public static int Count;
 
public SomeSubscriber(SomePublisher publisher)
{
publisher.SomeEvent += new EventHandler(publisher_SomeEvent);
}
 
~SomeSubscriber()
{
SomeSubscriber.Count++;
}
 
private void publisher_SomeEvent(object sender, EventArgs e)
{
// TODO: something
}
}

执行以下操作后将显示什么以及原因:

What would be printed after executing the following and why:

SomePublisher publisher = new SomePublisher();
 
for (int i = 0; i < 10; i++)
{
SomeSubscriber subscriber = new SomeSubscriber(publisher);
subscriber = null;
}
 
GC.Collect();
GC.WaitForPendingFinalizers();
 
Console.WriteLine(SomeSubscriber.Count.ToString());

推荐答案

C#编译器可以帮助您解决这一问题.只需下载visual studio(用作编译器的简易包装)并进行以下操作即可:

祝你好运！

The c# compiler can help you out with that. Just download visual studio (to use as an easy wrapper for the compiler) and give it a go:
