多值Cookie

  保存单值Cookie：
               HttpCookie SingelValueCookie=new HttpCookie("test1","单值Cookie");
               SingleValueCookie.Expires=DateTime.Now.AddDays(1);
               Response.Cookies.Add(SingleValueCookie);
                 等价于：
               HttpCookie SingleValueCookie=new HttpCookie("test1");
               SingleValueCookie.Value="单值Cookie";
               SingleValueCookie.Expires=DateTime.Now.AddDays(1);
               Response.Cookies.Add(SingleValueCookie);
        保存多值Cookie：
               HttpCookie MultiValueCookie=new HttpCookie("test2");
               MultiValueCookie.Values.Add("key1","value1");
               MultiValueCookie.Values.Add("key2","value2");
               MultiValueCookie.Expiress=DateTime.Now.AddDays(1);
               Response.Cookies.Add(MultiValueCookie);
                 等价于：
               HttpCookie MultiValueCookie=new HttpCookie("test2");
               MultiValueCookie.Values["key1"]="value1";
               MultiValueCookie.Values["key2"]="value2";
               MultiValueCookie.Expires=DateTime.Now.AddDays(1);
               Response.Cookies.Add(MultiValueCookie);

 

 

  **读取Cookie：
       读取单值Cookie：
              HttpCookie SingleValueCookie=Request.Cookies["test1"];
              string CookieValue= SingleValueCookie.Value;
              string CookieExpires=SingleValueCookie.Expires.ToString();
       读取多值Cookie：
              HttpCookie MultiValueCookie=Request.Cookies["test2"];
              MultiValue.value==>结果为：key1=value1&key2=value2;
              foreach(string subkey in MultiValueCookie.Values.AllKeys)
              {
                  string value1=MultiValueCookie.Values["subkey"];
                  string Expires=MultiValueCookie.Expires;
              }
