How to save and retrieve Cookie as single cookie or Collection of cookies in ASP.Net MVC

Hi florenz,

You cant simply store cookies in a collection if you want to assign list of values to a single cookie refer below

//Like below you can add mulitple values to single cookie.
HttpCookie cookie = new HttpCookie("YourCookieName");
cookie.Values.Add("YourCookieParameterName", "Your Value");
cookie.Values.Add("YourCookieParameterName", "Your Value");
cookie.Values.Add("YourCookieParameterName", "Your Value");
cookie.Values.Add("YourCookieParameterName", "Your Value");
Response.SetCookie(cookie);

//Like below you can retreive it by cookie name.
Request.Cookies["YourCookieName"]

//Like below you can retreive particular cookie value by cookie name and cookie Key.
Request.Cookies["YourCookieName"]["YourCookieParameterName"]

and if you want to have multiple cookies and assign them different values then you can do like below

//Like below you can add mulitple values to single cookie.
HttpCookie cookie = new HttpCookie("YourCookieName");
cookie.Values.Add("YourCookieParameterName", "Your Value");
cookie.Values.Add("YourCookieParameterName", "Your Value");
Response.SetCookie(cookie);

HttpCookie cookie1 = new HttpCookie("YourCookieName");
cookie1.Values.Add("YourCookieParameterName", "Your Value");
cookie1.Values.Add("YourCookieParameterName", "Your Value");
Response.SetCookie(cookie);

//Like below you can retreive it by cookie name.
Request.Cookies["YourCookieName"]

//Like below you can retreive particular cookie value by cookie name and cookie Key.
Request.Cookies["YourCookieName"]["YourCookieParameterName"]
