Cookies create object as list

A cookie stores only string data. The only way to do that would be to serialize it as a string (xml, json, base-64 of arbitrary binary).

@
{
string val = "";
if (Request.Cookies["myObjectKey"] != null)
{
List<string> myObject = new JavaScriptSerializer().Deserializestring>>(Request.Cookies["CookieName"].Value);
}
}
public void StoreCookie()
{
// create our list
List<string> data = new List<string>();
data.Add("one");
data.Add("two");
string myObjectJson = new JavaScriptSerializer().Serialize(data);
var cookie = new HttpCookie("myObjectKey", myObjectJson)
{
Expires = DateTime.Now.AddYears(1)
};
HttpContext.Response.Cookies.Add(cookie);
}
