public partial class Cookies : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
//清除cookies
// Request.Cookies..clear();
//将cookies["username"]置空
HttpCookie usercookie = Request.Cookies["username"];
usercookie.Expires = System.DateTime.Now.AddDays(-10);
// usercookie.Expires=.AddDays(-1.0);
Response.Cookies.Add(usercookie);
}
protected void Button2_Click(object sender, EventArgs e)
{
//读取cookies
HttpCookie mycookie = Request.Cookies["username"];
Response.Write(mycookie.Value);
}
protected void Button3_Click(object sender, EventArgs e)
{
//写入cookies
HttpCookie usercookie = new HttpCookie("username", "test");
//usercookie.Expires = System.DateTime.Now.AddMinutes(1);
usercookie.Expires = System.DateTime.Now.AddDays(1);
Response.Cookies.Add(usercookie);
}
}
