设置：

HttpCookie cookie = new HttpCookie("cookieName"); 
cookie.Value = "name1"
HttpContext.Current.Response.Cookies.Add(cookie);

读取：

HttpContext.Current.Request.Cookies["cookieName"].Value

判断cookie是否存在：

if(HttpContext.Current.Request.Cookies["cookieName"]==null){
//do something
}

设置cookie有效期

cookie.Expires = DateTime.Now.AddDays(1);
