asp.net操作cookie

//方式1:
Response.Cookies["username"].value="gggg";
Response.Cookies["username"].Expires=DateTime.MaxValue; 

//方式2:
HttpCookie acookie = new HttpCookie("last");
acookie.Value="a";
acookie..Expires=DateTime.MaxValue; 
Response.Cookies.Add(acookie);

//多值Cookie的写法 

//方式1:
Response.Cookies["userinfo1"]["name"].value="aaa";
Response.Cookies["userinfo1"]["last"].value="a";
Response.Cookies["userinfo1"].Expires=DateTime.MaxValue; 

//方式2:
HttpCookie cookie = new HttpCookie("userinfo1");
cookie.Values["name"]="aaa";
cookie.Values["last"]="a";
cookie.Expires=DateTime.MaxValue; 
//cookie.Expires = System.DateTime.Now.AddDays(1);//设置过期时间  1天
Response.Cookies.Add(cookie);

		

if (Request.Cookies["userName"]!=null)
...{
  string str = Request.Cookies("userName").Value; 
}

//多值Cookie的读取
if (Request.Cookies["userInfo1"]!=null )
...{
  string name=Request.Cookies["userInfo1"]["name"];
  string last=Request.Cookies["userInfo1"]["last"]; 
}


//读取 Cookie 集合
for(int i = 0 ;i<Request.Cookies.Count ;i++)
...{
    HttpCookie cookies = Request.Cookies;
    Response.Write("name="+cookies.Mame+"<br/>");
    if (cookies.HasKeys )//是否有子键
    ...{
        System.Collections.Specialized.NameValueCollection NameColl 
                                             = aCookie.Values ;
        for(int j=0;j<NameColl.Count;j++)
        ...{
            Response.Write("子键名="+ NameColl.AllKey[j] +"<br/>");
            Response.Write("子键值="+ NameColl[j] +"<br/>");
        }

    }
    else
    ...{
        Response.Write("value="+cookies.Value+"<br/>");        
    }
}

		

//删除cookie下的属性


 HttpCookie acookie=Request.Cookies["Info"];
 acookie.Values.Remove("userid");
 acookie.Expires = DateTime.Now.AddDays(1);
 Response.Cookies.Add(acookie);        

//删除所有cookie，就是设置过期时间为现在就行了

 ...{
     acookie = Request.Cookies(i)
     acookie.Expires = DateTime.Now.AddDays(-1)
