Cookie问题 [英] Problem with cookies
本文介绍了Cookie问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
这是我第一次尝试使用cookies，尽管阅读了一些
tutotials，但我真的很难让它正常工作。我的饼干
阅读代码在Master Page中。当我点击一个测试按钮（在aspx页面内的WEb
用户控件中）时，cookie值显示在Master
Page中，但是如果我转到另一个页面，没有显示任何价值...
我需要能够在整个网站上使用cookie的价值......我是什么？
做什么错误？
WebUser控件中的代码，这个代码点击按钮事件：
8< --------- ------------
HttpContext.Current.Response.Cookies [" TestValue"]。Value = mstrMyValue;
HttpContext.Current.Response.Cookies [" TestValue"]。Expires =
DateTime.Today.AddDays（365）;
----- ----------------> 8
此代码在我母版页的OnPreRender中：
8< ---------------------
if（Request.Cookies [" TestValue"]！ = null）{
litCookieTest.Text = Response.Cookies [" TestValue"]。值;
}其他{
litCook ieTest.Text = Request.Cookies [" TestValue"]。Value;
}
----------------- ----> 8
This is the first time I try to use cookies, and despite of reading some
tutotials, I''m have real trouble to make it work correctly. My cookie
reading code is in Master Page. When I click on a test button (in a WEb
User Control inside the aspx page), cookie value is displayed in Master
Page but if I go to another page, no value is displayed...
I need to be able tu use cookie''s value across all the site... What am I
doing wrong ?
Code in WebUser control, this code on a button click event:
8<---------------------
HttpContext.Current.Response.Cookies["TestValue"].Value = mstrMyValue;
HttpContext.Current.Response.Cookies["TestValue"].Expires =
DateTime.Today.AddDays(365);
--------------------->8
And this code in OnPreRender of my Master page:
8<---------------------
if (Request.Cookies["TestValue"] != null){
litCookieTest.Text = Response.Cookies["TestValue"].Value;
}else{
litCookieTest.Text = Request.Cookies["TestValue"].Value;
}
--------------------->8
推荐答案
Patxi，
如果在OnPreRender中放置断点事件处理程序是否一直调用
它不会一直调用。是因为缓存？

Patxi,
If you put a breakpoint in the OnPreRender event handler does it get called
all the time
It is not called all the time. Is it due to caching??

Kevin，
即使mstrMyValue =" SomeValue"它仍然不起作用
页面之间的Cookie值丢失。
谢谢

Kevin,
Even if mstrMyValue = "SomeValue" it still does not work
the Cookie value is lost between pages.
Thanks
