程序集如何找到开发人员编写的命名空间？ ??

I''m confused about the proper use and usefulness of namespaces. I beleive I
understand the purpose is so the developer can put classes within namespaces
to essentially organize your code. And I understand that you declare your
intention to use a namespace within a page through the "Inherits" attribute.
I know that using "Inherits" isn''t absolutely necessary, it''s just
recommended so the developer doesn''t have to type out the entire namespace
in code. I know that namespaces have to appear in the project assembly,
however...

How does the assembly find a namespace that the developer has written????
In all the examples I''ve seen, namespaces have been written in codebehind
pages. How does this make them accessible to the entire project? What''s to
prevent a duplicate namespace from being written in a different codebehind
page? Is there a better place to write all the project namespaces for more
centralized accessibility?

And finally, how do namespaces DIFFER from classes?

推荐答案

首先，命名空间可以与''Imports''关键字一起使用，所以不能

必须为每个类写出完整的命名空间，而不是''Inherits''

属性。


想想名称空间作为文件系统中的文件夹，类作为文件

。因此，命名空间本身不仅仅是一个组织

容器的类 - 就像文件夹只是文件的容器一样。

类是实际的东西你实例化，并调用方法。


我真的不明白你的问题。我认为它们都源于不了解命名空间实际上是什么。

First of all, namespaces can be used with the ''Imports'' keyword, so as not
have to write out the full namespace for every class, not the ''Inherits''
attribute.

Think of namespaces as folders in your file system, and classes as the files
in them. So a namespace itself isn''t anything but an organizational
container for classes - just as a folder is just a container for files.
Classes are the actual things that you instantiate, and call methods on.

I didn''t really understand your questions. I think they all stem from not
understanding what a namespace actually is.

嗯。我正在尝试从示例，教程和书籍中自学。

特别是在这种情况下，我正在尝试从MS PortalStarterKit学习。

具体来说，该示例中的默认页面为第一行

default.aspx：


<％@ Page CodeBehind =" Default.aspx.vb" ;语言= QUOT; VB" AutoEventWireup =" false"

Inherits =" ASPNET.StarterKit.Portal.CDefault" ％>


代码隐藏页面包含：


命名空间ASPNET.StarterKit.Portal

公共类CDefault

继承System.Web.UI.Page

Private Sub Page_Load（ByVal sender As System.Object，ByVal e As

System.EventArgs）Handles MyBase.Load

< code here>

End Sub

End Class

End Namespace


我试图找出它的工作方式和原因。这比教程和书籍给出的例子更复杂。


再次，我想弄清楚命名空间是如何声明的这里是

它进入大会的方式。并且因为它确实在某种程度上使整个项目可以获得
？

Hmm. I''m trying to teach myself from examples and tutorials and books.
Specifically in this case, I''m trying to learn from the MS PortalStarterKit.
Specifically, the default page in that example has as the first line in
default.aspx:

<%@ Page CodeBehind="Default.aspx.vb" language="vb" AutoEventWireup="false"
Inherits="ASPNET.StarterKit.Portal.CDefault" %>

The codebehind page has:

Namespace ASPNET.StarterKit.Portal
Public Class CDefault
Inherits System.Web.UI.Page
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
<code here>
End Sub
End Class
End Namespace

I''m trying to find out how and why this works the way that it does. It''s
more complex than the examples given by tutorials and books.

And again, I''m trying to figure out how the namespace declared here makes
it''s way into the assembly. And because it does, somehow, does that make it
available through the entire project?
