IDisposable的 [英] Idisposable

问题描述

用于实现IDisposable的VB.Net文档有：


受保护的可覆盖过载Sub Dispose（ByVal disposing As Boolean）

如果处置那么

''免费其他州（管理对象）。

结束如果

Tag.Dispose（）

''免费赠送你自己的state（非托管对象）。

''将大字段设置为null。

结束Sub


我无法理解评论：

什么是状态（托管对象）意思是

什么是状态（非托管对象）意思是

我理解托管对象和非托管对象，比如com对象，某些

GDI对象是不受管理的，应该放在这里。但

" state"是什么意思？

丹尼斯在休斯顿

VB.Net Documentation for implementing IDisposable has:

Protected Overridable Overloads Sub Dispose(ByVal disposing As Boolean)
If disposing Then
'' Free other state (managed objects).
End If
Tag.Dispose()
'' Free your own state (unmanaged objects).
'' Set large fields to null.
End Sub

I am having trouble understanding the comments:
What does "state (managed objects)" mean
What does "state (unmanaged objects)" mean
I understand managed objects and unmanaged objects like com objects, certain
GDI objects are unmanaged and should be disposed here. But what does the
"state" mean?

推荐答案

它只是意味着该对象将从其持有的任何资源中解脱出来，因​​此它将不再是有状态的。不要让措辞

挂起你。

It just means that the object would free itself from whatever resources it
was holding, thus it would no longer be statefull. Don''t let the wording
hang you up.

谢谢。我想状态只是意味着它的实例存在并且

托管对象将释放自己（有时），而我必须释放所有我自己的状态非托管对象GDI笔等等。


" Scott M."写道：

Thanks. I guess the State just means that the instance of it exists and the
managed objects will free themselves (sometime) whereas I have to free all my
own state unmanaged objects like the GDI pens, etc.

Scott，它会如果你能给我一个例子，那将非常有帮助：


a状态管理对象和你自己的状态非托管对象。例如，

是GDI Pen状态管理对象。或者我自己的州管理对象


我真的很感谢你帮助我理解这一点。


Dennis"写道：

Scott, it would be very helpful if you could give me an example of :

a State Managed Object and a "your own State unmanaged object. For example,
is a GDI Pen "state managed object" or my own state managed object"

I really appreciate you helping me to understand this.
