在asp.net C#中创建简单的cookie [英] creating simple cookies in asp.net c#

问题描述

我的应用程序需要存储cookie.当用户登录时，我想确保如果cookie不存在，请创建它并存储它的值，但是如果它确实对其进行了修改.

My application needs to store cookies. When a user logs on I want to make sure that if the cookie does not exist create it and store value, but if it does modify it.

if(cookieExist)
 {
    cookiename = "value";
 }
else
 {
   create a new cookie 
   then store the value;
 }

推荐答案

您必须使用 Request.Cookies 获取cookie值，并使用 Response.Cookies 添加cookie

You have to use Request.Cookies to get cookie value and Response.Cookies to add cookies

 string cookievalue ;
 if ( Request.Cookies["cookie"] != null )
 {
    cookievalue = Request.Cookies["cookie"].ToString();
 }
 else
 {
    Response.Cookies["cookie"].Value = "cookie value";
     Response.Cookies["cookie"].Expires = DateTime.Now.AddMinutes(1); // add expiry time
 }
