c#Cookie的使用

創建

 HttpCookie cookie = new HttpCookie("name");
            cookie.Value = HttpUtility.UrlDecode("豬剛烈", Encoding.GetEncoding("UTF-8"));   //HttpUtility   這個是用來編碼 解碼的
            cookie.Expires = DateTime.Now.AddDays(1);    //設置過期時間
            Response.Cookies.Add(cookie);

讀取

TextBox1.Text = HttpUtility.UrlDecode(HttpContext.Current.Request.Cookies["name"].Value, Encoding.GetEncoding("UTF-8"));

刪除     只要將過期時間設為負數就刪除了。。

HttpCookie cookie = new HttpCookie("name");
            cookie.Expires = DateTime.Now.AddDays(-21);
            Response.Cookies.Add(cookie);
