asp.net如何使用cookies

Question

asp.net如何使用cookies

Answer 1

Response.Cookie("username").value="aa" 写入
username=Request.Cookies("username").value 读取
最好用SESSION比较方便
session("username")="aa" 写入
username=session("username") 读取

Answer 2

C# :

方法1:
Response.Cookies["username"].Value="gjy";
Response.Cookies["username"].Expires=DateTime.Now.AddDays(1);

方法2:
System.Web.HttpCookie newcookie=new HttpCookie("username");
newcookie.Value="gjy";
newcookie.Expires=DateTime.Now.AddDays(1);
Response.AppendCookie(newcookie);

创建带有子键的cookies:
System.Web.HttpCookie newcookie=new HttpCookie("user");
newcookie.Values["username"]="gjy";
newcookie.Values["password"]="111";
newcookie.Expires=DateTime.Now.AddDays(1);
Response.AppendCookie(newcookie);

cookies的读取:

无子键读取:
if(Request.Cookies["username"]!=null)
{
Response.Write(Server.HtmlEncode(Request.Cookies["username"].Value));
}

有子键读取:
if(Request.Cookies["user"]!=null)
{
Response.Write(Server.HtmlEncode(Request.Cookies["user"]["username"].Value));
}

Answer 3

vb:
'COOKIE中设置
'帐号
Response.Cookies("userId") = userId
Response.Cookies("userId").Expires = 60 '保存时间，以天为单位
'密码
Response.Cookies("pw") = pw
Response.Cookies("pw").Expires = 60

'从COOKIE取得
Response.Cookies("userId")
Response.Cookies("pw")

如果Cookies中无值，取得为空字符串""
