IDisposable的问题 [英] IDisposable Question

问题描述

说我有以下几点：

public abstract class ControlLimitBase : IDisposable 
{
}

public abstract class UpperAlarmLimit : ControlLimitBase 
{
}

public class CdsUpperAlarmLimit : UpperAlarmLimit 
{
}

两个问题：

1。
我就当我IDisposable的成员实际上被调用有点困惑。将用在CdsUpperAlarmLimit实例超出范围，他们被调用？

1. I'm a little confused on when my IDisposable members would actually get called. Would they get called when an instance of CdsUpperAlarmLimit goes out of scope?

2。
我将如何处理在CdsUpperAlarmLimit类创建的对象的处置？如果这也从IDisposable接口派生？

2. How would I handle disposing of objects created in the CdsUpperAlarmLimit class? Should this also derive from IDisposable?

推荐答案

的Dispose（）从不自动调用 - 这取决于代码是如何实际使用

Dispose() is never called automatically - it depends on how the code is actually used.

1）的Dispose（）时被调用。你特别呼吁的Dispose（）：

1.) Dispose() is called when you specifically call Dispose():

myAlarm.Dispose();

2）的Dispose（）被称为在使用你的类型的实例的使用块的结尾。

2.) Dispose() is called at the end of a using block using an instance of your type.

using(var myAlarm = new CdsUpperAlarmLimit())
{

}

的

使用块是一个尝试/终于有一个呼叫阻塞<$ C $语法糖正在使用C>的Dispose（）的对象在finally块。

The using block is syntactic sugar for a try/finally block with a call to Dispose() on the object "being used" in the finally block.
