提问by user516883
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.
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，则创建它并存储值，但如果它确实修改了它。
if(cookieExist)
{
cookiename = "value";
}
else
{
create a new cookie
then store the value;
}
Thanks for any help

You have to use Request.Cookiesto get cookie value and Response.Cookiesto add cookies
您必须使用Request.Cookies来获取 cookie 值并Response.Cookies添加 cookie
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
}
