处理问题 [英] Disposing question
问题描述
我一直在看一个例子，有些东西我不会理解。
给定：form1调用form2
---------
问题：在form2中使用这些行有什么用？
---- ----------
使用System.ComponentModel;
....
private System.ComponentModel.Container组件= null;
....
protected override void Dispose（bool Disposing）
{
if（处理）
{
components.Dispose（）;
}
base.Dispose（disposing）; < br $>
}

它们是必需的，因为System.Windows.Forms .Form继承自Component
，这要求Dispose过度使用deen for Garbage Collection（在外行人的
条款......）;）

使用System.ComponentModel;

protected override void Dispose（ bool Disposing）

我明白如果你需要一个Dispose，你需要覆盖和
重新定义Dispose。但我不明白为什么我需要它，因为C＃
自动收集垃圾，除非我去外面
.NET框架

I have been looking at an example, and there is something I don''t
inderstand.
Given: form1 calls form2
---------
Question: What is the use of having these lines in form2
--------------
using System.ComponentModel;
....
private System.ComponentModel.Container components = null;
....
protected override void Dispose(bool Disposing)
{
if(disposing)
{
components.Dispose();
}
base.Dispose(disposing);
}

which requires Dispose to be overrideen for Garbage Collection (in layman''s
terms...) ;)

I do understand that if you need a Dispose, you need to override and
redefine Dispose. But I don''t understand why I need it because C#
looks after the garbage collecting automatically, unless I go outside
the .NET framework
