问题描述

如何使用C＃删除asp.net中的缓存，cookie，隐藏字段请提供一些如何实现它的示例???

解决方案

在这里。 。

删除缓存：

 Response.Cache.SetExpires（DateTime.UtcNow.AddMinutes（-1） ）; 
 Response.Cache.SetNoStore（）; 
 Response.Expires = -1500; 

删除Cookie：

 cookie.Expires = DateTime.Now.AddYears（-30）; 
 context.Response.Cookies.Add（cookie）; 

删除HiddenField：

  HiddenField.Delete（） 
  //  抱歉，只是在这里开玩笑 

您无法删除HiddenField。相反，您可以将HiddenField的值设置为空。

 HiddenField.Value =  ;

hi，

 //在Cookie创建期间设置其到期时间。 
 HttpCookie cookie = new HttpCookie（test）; 
 // Cookie在1天后过期
 cookie.Expires = DateTime.Now.AddDays（1）; 
 //添加Cookie 
 Response.Cookies.Add（cookie）; 
 
 //你不能删除隐藏的字段。 
 //将隐藏字段的值设置为空白
 hdnData.Value =; 
 
 //对于缓存过期
 Response.Cache.SetExpires（DateTime.Now.AddSeconds（60））; 
 Response.Cache.SetCacheability（HttpCacheability.Public）; 
 Response.Cache.SetValidUntilExpires（true）;

How to delete cache,cookie,hiddenfield in asp.net using C# please provide some examples to how to implement it???

解决方案

Here you go..
Deleting Cache:

Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1));
Response.Cache.SetNoStore();
Response.Expires = -1500;

Deleting Cookie:

cookie.Expires = DateTime.Now.AddYears( -30 );
context.Response.Cookies.Add( cookie );

Deleting HiddenField:

HiddenField.Delete()
//Sorry, just kidding here

You cannot delete the HiddenField. Rather you can set the value of the HiddenField as empty.

HiddenField.Value = "";

hi,

// During the time of Cookie Creation Set its expiration time.
       HttpCookie cookie=new HttpCookie("test");
       // Cookie expire after 1 day
       cookie.Expires = DateTime.Now.AddDays(1);
       // Add Cookie
       Response.Cookies.Add(cookie);

       // you cann''t delete hidden field.
       // Set value of hidden  field to blank
       hdnData.Value = "";

       // For Cache Expiration
       Response.Cache.SetExpires(DateTime.Now.AddSeconds(60));
       Response.Cache.SetCacheability(HttpCacheability.Public);
       Response.Cache.SetValidUntilExpires(true);
