推荐答案

您必须继承控件才能访问ViewState之类的东西。对于

示例，您希望扩展您要执行的页面类：


公共类ExtendedPage：System.Web.UI.Page

我不确定这是不是你问的问题，但这是我所理解的

你的问题

You have to inherit the control to access things like the ViewState. For
example you want to extend the page class you would do:

public class ExtendedPage : System.Web.UI.Page
I''m not sure if that''s what you''re asking but that''s what I understood from
your question

您好Alphonse，


从您的描述中，您的意思是如何引用一个页面或用户控件来自另一个类的
，这个类是否意味着一个类似于想要与b
隔离的实用类与网络相关的信息？


如果是这样，我认为有两种方法可以选择：

1.在某个类中定义一个函数，其中包含一个param类型

其中Page是或UserControl那么，你可以参考某些

页面或UserControl的成员：例如：

公共类...

public void processPage （页面页）

{

page.XXX。 = xxxx;

}


public void processUserControl（UserControl uc）

{

uc。 xxxx = xxx;

}

2.在ASP.NET web应用程序中，HttpContext.Current静态成员提供

对当前处理的引用请求'上下文，如果

请求'的处理程序是一个Page处理程序（或者从
System.Web.UI.Page派生的其他类），我们可以使用HttpContext.Current.Handler获取

当前页面的引用，例如：


public void processPage（）

{

页页=（页）HttpContext.Current.Handler;

page.XXX = xxx;

}


另外，这里有一些前线程讨论类似的

Hi Alphonse,

From your description, you means how to reference a page or user control
from another class, does the class you mean a utilitiy class which want to
be isolated with the web related infos?

If so, I think there are two means you can choose:
1. Define a function in the certain class which contains a param the type
of which is "Page" or "UserControl" then, you can reference the certain
Page or UserControl''s members: For example:
public class ...
public void processPage(Page page)
{
page.XXX. = xxxx;
}

public void processUserControl(UserControl uc)
{
uc.xxxx = xxx;
}
2. In ASP.NET web applicatoin the HttpContext.Current static member provide
the reference to the current processed Request''s Context and if the
request''s handler is a Page handler(or other classes derived from
System.Web.UI.Page), we can use the HttpContext.Current.Handler to get the
Current Page''s reference ,such as:

public void processPage()
{
Page page = (Page)HttpContext.Current.Handler;
page.XXX = xxx;
}

In addtion, here are some former threads discussing on the similar
questions:

感谢您的回复。


It看起来你已经为我钉了它Steven。


我应该提到我在VB.NET工作。虽然我很熟悉

的一些c＃语法，但我不太明白以下几行：

Page page =（Page）HttpContext.Current.Handler;

VB中的等价物是什么？


另外，使用方法1与方法2的性能有何不同？

Thanks both for the replies.

It looks like you have nailed it for me Steven.

I should have mentioned that I am working in VB.NET. While I am familiar
with some of the c# syntax, I don''t quite understand the following line:
Page page = (Page)HttpContext.Current.Handler;
What would be the equivalent in VB?

Also, is there any difference in performance using method 1 vs. method 2?
